Chapter 5 10

The two detectives Jindai and Higashi returned to Tokyo, feeling tired.I originally planned to talk to Shibamura directly in the third step, but now I have lost my courage. However, is it possible for a married woman who entered a hotel in Kyoto with her lover, left her luggage the next night and left without saying goodbye, and returned to Tokyo as a dead body? At the same time, her husband was driving a 20-foot yacht in the sea off the seven islands of Izu, and Ueda, who was on the same boat, listened to the sound of the wind and watched the waves and spray.What happened on both sides, although the time is the same, the space is separated.

No one knows where Miyako was when Shibamura's Seabird suffered an unfortunate accident in Sagami Bay where Ueda fell into the sea.But she was on land for sure.This is also far apart in space. Even so, Jindai and Dong still have doubts that cannot be relieved.Because they inadvertently tried to connect the operation of Miyako who disappeared from the roof of the hotel in Kyoto with the misfortune of the Seabird that killed Goro Ueda.They try to make homework that seems unnatural and unreasonable in their hearts.They look for adhesives for joining. Ihara, the general director of the Rugby Club, said that the turning of the mast is an irresistible force.Ihara is the general manager of the club, so it is right to comfort the players.Even so, his tone still reveals that the buckling of the sail mast was caused by a bit of steering error.

Steering mistakes are man-made, and man-made has a subtle difference between negligence and forgery.Besides, in the sea where no one can see.Of course, there were only two people involved in the boat. The two detectives started with this first.Even so, don't expect to see the whole thing clearly.But anyway, it must be carefully thought out. However, no one can judge whether it was caused by negligence or falsification.Because there are no witnesses, and it cannot be inferred from the circumstances after the accident.So it can only be based on what Shibamura said, but of course I will not have any unfavorable explanations for myself.

Detective Jindai thought that he might be able to infer from Ueda Goro's body, so Detective Wadato went to Yokohama again. The Forensic Section of the Kanagawa Prefectural Police Station maintains forensic photos of all the corpses of abnormal deaths that have occurred recently.Ueda Goro is also one of them.Ueda's naked body is placed on a straw mat and photographs are taken from various angles.The most important thing is the photo of the back. The back of the head has a strong laceration, which is shaped like a headband.Although the two criminal policemen are not expert in forensics, they can also see that this scar cannot be caused by ordinary wooden knife attacks.

However, according to the explanation of the forensic class teacher, the blow was not a fatal injury, and he was not dead when he fell into the sea.The cause of death was drowning.This is further confirmation of the explanation I heard last time.However, it is impossible to judge from this photo whether the buckling of the mast that caused Ueda's death was the fault of Shibamura's steering, or whether it was a forgery. The office of the forensics class is quite large, and the class members are busy with their own work.The young East detective still didn't give up on Ueda's on-site photos, but Jindai had given up hope. He walked to the window to look at the cold weather, and let his tired soul temporarily rest.Despite the desire to connect Kyoto with the space of Sagami Bay, reality stubbornly scoffed at his attempt.

When Jindai left the window, he suddenly saw an open photography magazine on the desk of the class.Photography seems to be one of the jobs of the forensics class, so photography magazines are needed as a reference for further study.As a criminal policeman, he does not have such reference books.At most, there are only boring books such as search guide essentials or criminal procedure law essentials.Jindai smiled unconsciously, standing and looking down at the photo in the photo magazine. It was a good picture, with the sky evenly divided, the sky above with clouds hanging down, the trees and lush weeds below, and the sea in between.The location of the weeds is higher than the water level, so it may be shot from above the cliff.There is a narrow path among the lush weeds. A small figure walks on the path with his head down, as if he is heading towards the cliff on the other side of the sea.This is a landscape reminiscent of boyhood.The Shindai detective used to walk around the country lanes in his hometown like this when he was a child.

Good photo, Jindai praised in his heart.Take a look at the title below, printed with Manazuru Cape Morning. At this time, the East detective also gave up hope and walked over, standing side by side with Jindai to look at the photo.But he was anxious because the search could not progress, and the poetic and picturesque pictures on the photos did not meet his eyes. The two walked out of the county police headquarters, both of them were silent, with heavy expressions on their faces. After buying two tickets to Tokyo at Sakuragicho Station, Shindai pushed Higashi Detective on the shoulder and said:

Hello, come here. On the wall of the waiting room is a map of Kanagawa Prefecture, including parts of the neighboring Tokyo Metropolis and Shizuoka Prefecture. Cape Manazuru is here.Komyo pointed to a point on the map and said: The oil pot is over here. The east criminal policeman looked at the map, and then at the senior criminal policeman's face. He didn't understand what the other party meant? Shibamura's yacht should have broken down here. The finger of Jindai pointed to the place in the middle of Sagami Bay, which is between Cape Manazuru and Oil Pot, and just to the north is Chigasaki or Hiratsuka.The connecting line between the real crane and the oil pot is a horizontal line on the map.

Yes.East Detective replied, but he still didn't understand the meaning of Jindai. There is also the Big Island here. The big island mentioned by Jindai is to the east, and the blue line indicates that it is 139 degrees and 30 minutes east longitude. Miyake Island is on the line of 139°30 east longitude, so most of the boats going around Miyake Island half a circle back to Oilpot go straight north along this line of 139°30.Didn't Director Ihara of the rugby club say that?When going from Oilpot to Miyake Island, due to the headwind, the routes of the ships took a zigzag shape.The return voyage was with a fair wind, so there was no need for it, so it was a straight sail.Because of this, the return journey takes half the time of the outbound journey.So, the seabird's course was sailing at a place quite west of this one hundred and thirty-nine degrees thirty because that was the place of the wreck.

But isn't it subject to wind and tide? There are several factors.But what does it mean for the Seabird to sail west, where the terminal oiler is almost there? After listening to Jindai's explanation, East Criminal Police remained silent for a while. Did you see the photos in the photography magazine just now?That's a good photo. There's a person walking towards the prominence of Cape Manazuru. Don't go back to Tokyo. Go to Cape Manazuru. It's very close to Sagami Bay where Shibamura's Seabird died.It is not certain that he has been to Cape Manazuru.Don't you think it took too long for him to return to the oiler?Anyway, go to Cape Manazuru to see if there are any clues to look for?

11 It was two o'clock in the afternoon when Detective Shindai and Detective Higashi arrived at Manazuru Station. The taxi they took in front of the station took them to the low-lying urban area on the other side of the sea, and the police station was on the road that smelled like fish.They stopped in front of the police station and asked for the assistance of a police officer familiar with the local terrain.The policeman in his forties was called Yoshioka, and he led two criminal policemen up the road along the north coast.On one side was a hilly country full of orange groves, surrounded by cliffs. Shibamura said the place where his boat's mast capsized was off the Inamura Sea in Sagami Bay.It was thirty-five degrees seven minutes north latitude and one hundred thirty-nine degrees eleven minutes east longitude.It is conjectured that the cape of Manazuru, where Shibamura may have landed secretly, is at latitude 35°8 north.Five minutes, one hundred thirty-nine degrees and ten minutes east longitude.Or at the same latitude slightly west of the Cape, east longitude 139°9.Five points is called the inner pocket. There are no cliffs on the west side of the northern tip of the Manazuru Peninsula, only a straight coast, so there are fishing villages there, and there are many sightings when boats dock. Therefore, if you want to go to the shore, it is more likely to choose a protruding cape with no one else, or near the inner bag.The two detectives had the same idea, and the Yoshioka policeman nodded and said after hearing the content of the matter: Yes, if you don't want to be seen, that area is ideal. The three of them let the taxi drive to the prominence of the cape, then got out of the car and walked to the top of the cliff to look down. Countless small island-like rough rocks and reefs were scattered in the sea, and no ships were seen. The reef over there is called Sanshi, and it is a slightly famous place in this area.Yoshioka Police explained. When the weather is clear, you can see the Boso mountain on the other side of the sea, but today it is so hazy that you can't see it clearly.The road where they were standing was surrounded by forests of miscellaneous trees and bamboo groves, and there were no houses except summer oranges and small fruit juice shops for tourists. The Yoshioka police questioned the middle-aged woman in the small shop. She said that she came to open the shop at ten o'clock every morning, and closed the stall at five o'clock and went back to the city.When asked on the 17th if she saw a yacht moored on the nearby coast, the middle-aged woman shook her head and said she did not remember.A yacht is different from a fishing boat. Even if the date is not remembered, there should be an impression.But the middle-aged woman said that she had only seen the yacht race half a year ago. The three of them returned to the taxi, turned back the same way, got off at the intersection with a small road, and walked through the valley path between miscellaneous trees and bamboo bushes to the south coast.It is also on the cliff, and on the right you can overlook the coast along Sagami Bay.The faintly visible mountain directly opposite the sea is probably Ajiro.The sound of fishing boat engines can be heard. The cliff here is concave, so Jindai thought that if the yacht were to dock, it would be in this area.The Eastern Criminal Police also had the same opinion, but the Yoshioka Police who came together disagreed.He said that this place can be seen in the Moncheon area where there are many houses.Kadogawa is a fishing village near Yugawara on the right, and small fishing boats can still be seen going in and out there. I think that if a rare yacht wants to dock, it should be on the side of Sanshi Cape we went to just now.Because it can't be seen from Manazuru Cape and Kadokawa, it is a dead end. But aren't there tourists over there?Will it be seen by tourists?East Criminal Police said. Yes.However, as long as I can avoid the occasional tourist, I think it is much safer there. The three of them returned to the road again, and the criminal police officer Shendai became more and more anxious. If he couldn't find the fact that the yacht had docked, his speculation would be completely ruined. Take the taxi back to the tip of the cape. The small shop is open every day except on rainy days, so unless you can ask the middle-aged woman for information, there is no other source of information.However, it is a pity to give up like this. When I came to the front of the small shop, I saw a middle-aged woman selling summer oranges talking with an old woman in her sixties.The old woman's pram had dead branches on it.Shindai in the taxi asked Yoshioka if he knew the old woman?Yoshioka replied that she was the mother of a fisherman in Manazuru.God stepped out of the taxi on behalf of the three of them. Hi old lady.Yoshioka walked towards the old lady with a smile on his face.Are you here to collect firewood today? Yes, three or four days, you have to come out and pick it up once.The old woman replied with wrinkles at the end of her eyes. Old lady, when do you usually come to collect firewood? Usually come out between one and two in the afternoon. The Yoshioka police made an inquiry in accordance with the wishes of the Shindai detective. Old lady, may I ask, did you come here to collect firewood on August 17th? August 17th, yes, yes, that day will come. The old lady has a good memory.It was also at one o'clock in the afternoon that day? No, it was at eight in the morning that day. What?Eight in the morning?The eyes of the police are shining, old lady, was there anyone else around here besides you at that time? Well, the old woman thought about it, and there seemed to be no one, because this small shop has not opened yet.Mr. Police, why are you asking this? It seemed that someone stayed in this area at that time, and we wanted to investigate this matter. Did not see any strange people. really not?You think again. No, there are no strange people. I just saw a man with a fishing rod walking down the cliff from the path over there. The Age of God immediately stepped forward and asked: Do you see what this man looks like or is dressed for his age? When I saw it, that person had already walked down from the woods in front, and he couldn't see clearly from a distance. The Yoshioka police explained that there are also people who love fishing in Tokyo who come to Cape Manazuru to fish early in the morning. What kind of clothes do you wear? What appears to be a tan short-sleeved shirt, black trousers, and a gray hiking hat.A hand-held dark blue bag looks like a fish cage or a bento box. Oh yes.So, is the fishing rod a foldable type, the kind that packs several rods into one bag? No, just holding a long pole. Your memory is really good, but how do you remember that it was indeed the morning of August 17th? It's easy. August 17th is the second day after the Obon Festival. My daughter married to Shizuoka. On the afternoon of the second day after the Obon Festival, I brought my grandson back to play.This matter was decided earlier, so I came early that day, at 8 am to collect firewood.So the date will not be wrong. Godhead nodded.After leaving the front of the shop, Jindai asked Yoshioka: Which is the way down the cliff that the old lady said? Over there, do you want to take a look? It was the end of a wide road, and after going more than a hundred meters from the bend, the path led into the miscellaneous forest. The three of them walked along the path, passing through the woods, and the surroundings turned into low bushes, with the sea in front of them.The path follows the cliff, forming a lightning pattern, and goes directly to the place where the waves beat the rocks under the cliff.On the other side of the sea where the Sanshi rock reef emerges, Boso's mountains stretch like thin clouds. Do people who come here for sightseeing go down there?God asked. Fishermen will go down this path to the place near the sea, but most people will not go there because they are afraid of danger.Most of the time we will turn around when we are standing here. Jindai looked down, there were only cliffs and rocky reefs, which were not suitable places for yachts to dock. The three returned to the place where the taxi was waiting, returned to the city, went to the front of the police station, thanked the Yoshioka policeman, and let him get off the bus. When there were only two detectives left, the East detective said: The man fishing was walking in that kind of place, which happened to be the same composition as that photo. Hmm, I didn't expect people to go to that kind of place.Kamito said disappointedly. Eight o'clock in the morning, isn't this time too early? The sooner the fisherman goes, the better. People from Tokyo or Yokohama may go there by train early in the morning.You can take a taxi from Manazuru Station. 12 The East Criminal Police was very interested in the fact that Miyako Shibamura disappeared without a sound on the roof of the hotel in Kyoto on the night of the 16th while Shinkichi Sone was concentrating on watching the flames of the large characters. Sometimes I accompany my wife to the streets, and when she leaves to go shopping alone, I suddenly feel that she might just leave like this and never come back.Do modern people often have this sense of unease?East detective said to Shendai detective. Maybe, you like reading novels, so you will think this way even more.I also don't understand how Miyako left Shinkichi Sone without saying a word while watching the flames on the roof of the hotel?It is impossible to be abducted by a violent group; and Shinkichi Sone also said that if he met someone he knew in common, he would definitely come back afterwards.This is for sure.Why didn't she come back to her lover?The key to the puzzle seems to be here. What was the reason why she couldn't return to her lover?The east detective said, looking at the approaching Manazuru station. Two young men and a woman passed by on the road. When the East Criminal Police saw them, they suddenly said in their mouths!With a sound.What did God ask him?He thought for a moment in silence, and replied: Mr. Jindai, Miyako could not speak to Shinkichi Sone, probably because her husband Shibamura appeared on the roof of the hotel at that time. What? I don't think there was any reason for Miyako's disappearance other than Shibamura's appearance.Her husband appeared in front of her eyes, so of course Miyako couldn't talk to her lover next to her.Because she told her husband that she was traveling to Nara to participate in the class reunion.Of course, she can argue that from Nara to Kyoto, reading big characters ignites the fire.However, Shibamura's friend Shinkichi Sone was also there, so it was impossible to tell. In order to prevent her husband from discovering the existence of Shinkichi Sone, Miyako has to leave the roof with her husband! The East Criminal Police became more and more excited about his thoughts. The lights on the roof had been turned off at the time, and Miyako took advantage of the moment of darkness to leave, and Shinkichi Sone might not have noticed what was happening behind him because he was attracted by the climax of the big text. Not bad.Jindai's expression seemed to feel that Dong Detective's words were not unreasonable. Yes, it is possible.Miyako certainly didn't want her husband to catch her infidelity on the spot, and she couldn't say that she lived alone in the hotel.She had no choice but to pretend nothing had happened, and left the hotel with her husband.It was easy for Shibamura to take his wife out of the hotel, because the hotel clerk also testified that there were many people watching the big characters that day.So when the hotel guest went out with other men, of course they wouldn't find out, the hotel didn't know the reason for her going out. However, can Shibamura appear on the roof of a hotel in Kyoto at that time?Shibamura should be in a distant sea yacht. The idea is good, but unfortunately it does not match the reality.Although Jindai sympathizes with East Detective, he has to point out the facts. Because Shibamura was driving a yacht at that time, on the sea from Miyake Island to Oilpot. It was an unshakable fact that Shibamura was sailing on dark seas at that time. Yes, that's the problem.East Criminal Police also showed a disappointed expression and said, if it weren't for this, my imagination would be full of reality. I think so too. The taxi turns the road, and Hakone's outer ring mountain towers high behind the urban area. Mr. Jindai, unless Shibamura has wings like those birds, it is absolutely impossible to fly from a yacht on the sea to the roof of a hotel in Kyoto. The East detective looked at the sparrows flying in groups in the distance and said. Kamito didn't answer, just meditating silently. Because Shibamura was on the yacht, he couldn't go to Kyoto.Because of this, it is assumed that Shibamura sent someone to lure Miyako off the roof of the hotel.But this is impossible, since Miyako's actions on the roof vetoed this assumption.If it were Shibamura's agent, Miyako would definitely consult with Shinkichi Sone.Even if I can't speak in front of the agent, I will contact him afterwards or go back to the room.The agent is not as scary as the person himself, and it is easy to find gaps. The fact that Miyako cannot tell her lover a word is the point that cannot be understood, unless her husband Shibamura himself appears in front of her, otherwise it is impossible. However, as the East Criminal Police said, Shibamura on a yacht sailing overseas must fly like a bird, otherwise this hypothesis cannot be established. So, is it using an airplane? The Age of Gods meditated. The two of them went to Atami, entered the tourist service center at the station, and investigated the domestic flight schedule of ANA. The Miyakejima Line departs from Haneda Airport every day. It departs from Haneda Airport at 2:20 pm and arrives at Miyakejima at 3:00.The flight stopped at Miyakejima for half an hour, left at 3:30, and returned to Haneda Airport at 4:20. Assume that Shibamura's ship docks at Miyakejima, lands, and takes a 3:30 plane to Haneda Airport.But at 3:30 in the afternoon, the yacht Seabird he was driving had circled Miyake Island for half a circle and reached the sea east of Kozu Island in the north. If the yachts participating in the competition must dock at Miyake Island, it is conceivable that Shibamura went ashore alone and let Goro Ueda drive the boat back to the oil pot alone. Jindai took out the notebook to read, and briefly recorded the news he inquired about.Yacht racing sources have this to say: This time, when the race arrived at Miyake Island, it was not necessary to dock. Instead, it sailed along the island for half a week at sea and returned to the oil pot.In some competitions, it is necessary to collect certificates at the turning point, but this competition respects the personality of the players, and it is a gentleman's agreement that this procedure is not required. What if only Shibamura's boat docked at Miyakejima, and he went ashore alone, and took the 3:30 p.m. flight to Haneda?From Haneda to Kyoto.This is also possible.On the train bound for Tokyo, the East Criminal Police said. But this is also difficult, because Ueda is still on board, and he cannot be left on board, and Shibamura goes ashore on Miyake Island alone.Unless Shibamura bought Ueda. As Jindai spoke, he suddenly realized what he had said.The Eastern Criminal Police also called out at the same time. Shibamura has won over Ueda, right?That's why Ueda was hit by the fan and fell into the sea after the incident. In fact, he was murdered by Shibamura, right? Accidents where the mast turns over can also happen artificially, right?It is usually caused by the sails being blown by strong winds when the ship changes direction suddenly.In other words, it was a mistake in steering. Since the reason lies in a mistake in steering, then this mistake can be intentional! According to the Yachting Club's director general, Shibamura has a pretty good craft.Therefore, Shibamura made Ueda Goro look like an accident, and was knocked into the sea by the sail pole. The fact that Shibamura landed on Miyake Island can be hidden from the world forever. Detective Dong told Detective Shindai what he thought, and Shindai felt the same way, but he had other questions. Dongjun, your guess is very good.However, assuming that Shibamura went ashore on Miyake Island alone, and Ueda sailed the Sea Bird to Oilpot alone, it would be no problem for Shibamura to fly from Miyake Island to Haneda and then transfer to Kyoto.But why is Shibamura able to be on the seabird yacht returning to Oilpot Port?Unless Shibamura can do magic, that's impossible. Um, that's right, Dong Detective, who was excited about his own thoughts, folded his head and pondered again. Also, how did Shibamura allow the boat to approach Miyake Island, which does not have to dock during the race?This is also a puzzling question. Yes, not bad. Dongjun, anyway, we can only solve the problems that are easy to solve step by step according to the problems we are currently facing.It is too difficult to solve all at once, but it is easy to disperse. So what to do?Where to start? Request to search the section chief and send a plane to Miyake Island. 13 At around 3:00 p.m. the next day, the two detectives, Jindai and Higashi, stepped out of the plane at a small airport near Miike Beach on Miyake Island.Of the passengers declared full, more than half were people in fishing gear from Tokyo, and the rest were people from the island, officials on business trips, four tourists and a newlywed couple.The fishermen, in civilian clothes, talked loudly about their craft.From their equipment, Jindai imagined the appearance of the man who walked down the beach from the tip of Manazuru Cape with a fishing rod on the morning of the 17th.There are many people who love fishing. The criminal police on the island came to the airport to meet the two of them, got into a police car, and drove to the General Administration.The Miyakejima Police Station of the Metropolitan Police Department is in Izu, and the airport is located on the east side of the island. Therefore, it is necessary to bypass the paved road at the foot of Mount Xiongshan in the center of the island for about ten kilometers to reach Izu in the north. The traffic between Tokyo and Miyakejima has been very convenient since the opening of domestic routes.In the past, we could only take a boat. We set sail from Tokyo in the evening and arrived at Okubo on the north shore of Miyake Island at 6:00 the next morning.And usually there is only one boat every three days. Looking from the car window, there are almost no houses on the highland on the left, and the black pine virgin forest is lush and lush above the lava field. On the right, you can see the beach and harbor with calm waves.Interpol explained that there is Miikehama.The places where pedicure is dried can be seen everywhere.Mikurajima is also in sight.For a while, enter the Cape Roots and temporarily leave the shoreline. This is called Sada Cape. Said a policeman.Passing there, the primeval forest also ends, turning into a desolate landscape of black-brown lava.Roads are carved out of lava. This area is called Akaba Akatsuki. It was formed when the lava erupted when the Xiongshan volcano erupted in the 15th year of the Showa era (1940). Exactly the same as Karuizawa's ghost out. East Criminal Police said.But Jindai thinks of the lava field of Sakurajima.On the right is still a terracotta lava basin, but part of it is a desert-like gravel area. Hot springs gushing out of the sand over there are open-air baths.That's what formed when it breathed fire.Interpol said, but could not see a house. Only occasionally people from nearby came to take a bath, and there were no tourists, so no hotels were built.Interpol went on to explain. Leaving the lava field, pass the small village called Shimo Noo, to the north of the island.The nearby coastline is full of cliffs.Soon after entering the lava field, after passing here is the village called Shenzhuo. The Miyake Branch Office of Tokyo Metropolitan Government is located here.A criminal policeman explained. This is the harbor, the road becomes higher, and Niijima can be seen.Go down the road to Izu Village, where the police station is located.It was almost four o'clock. Shindai and Higashi Detectives were brought into the criminal police room, greeted Director Miyakejima, and then unfolded the detailed map of Miyakejima. The entire Miyake Island is circular, and the Xiongshan volcano is entrenched in the center.About at the belly of Xiongshan Mountain, it seems to divide the island into two halves, passing through the line of 139°30 east longitude.The thirty-fourth parallel north latitude passes through the sea in the south of the island and intersects with the longitude.The road winds along the coastline at the foot of the mountain, and it is said that it takes about an hour to drive around.In the past, people on this island called circling the island a trip, and they had to stay overnight to complete the circling, but now it can be completed in an hour's drive. Which part of the island is easiest for yachts to enter? It is said that it is Kaibin near Agu in the west and Pingtian in the south.Especially Saihama, where the ships of the Tokyo Yacht Club often dock, and there are also famous movie stars among them. There are also Ofunato Bay on the west and Miikehama on the east. Are there any others? Except for these few places, the other coastlines are cliffs, which are not suitable for docking. Jindai told the detectives of his intentions and asked to investigate whether anyone saw the yacht docking between 9:00 am and 11:00 am on August 16th.The matter is best entrusted to the local police to investigate.The criminal police of the Headquarters who do not know the local residents must have many difficulties in order to inquire about the news. It's best to have the results by 3:30 tomorrow afternoon before we leave. With the director's understanding, the criminal police promised to fully assist. How about going halfway around the island now?I haven't seen it on the west side yet, so it's better to go and see it first.An hour round trip is enough. Although it was nearly six o'clock, the summer sun was still bright.Accompanied by three criminal policemen, the two of them set off in the director's car. After leaving Izu Village, the paved road goes around the foot of Mount Oyama along the west coast. Soon enter the village of Izu, which is the deepest Onunato Bay on the island.From here to Agu, the foot of the mountain becomes a steep slope.The village can be seen on the terrace made of stone walls, and Kozu Island is floating near the sea. There are hot springs on the coast here.Interpol said. When I came here just now, there was also an open-air hot spring bath in the lava sand field to the east. After passing the small village of Agu, not far from the cross road, you will arrive at the deep harbor of Kaibin Fishing Port.Because it is said that yachts are often moored here, the two criminal policemen took a closer look, but at this time they could not see any sails.Further south through the small village of Bomu to Pingtian at the southern end, the coast is full of rocky cliffs, and there are fishermen on the cliffs. In addition to buses, grazing cattle are also strolling leisurely on the road.Dairy farming flourished on the island.On the road, there are Crater Lake Xinchuan and Dalu Pond, which are parasitic volcanoes on Mount Xiongshan, but the Dalu Pond, which is overgrown with water and grass such as Shihulan, can only be seen by listening to the instructions, and cannot be seen from the car.There are two people who look like tourists nearby. The car decided to go back to Pingtian, and then it was the same road as before.The criminal police who came together got off the car at Pingtian and asked for the news that God Dai and the others wanted. When I returned to Agu, I happened to watch the beautiful sunset on the sea.After the yellow sun fell into the purple cloud, its brilliance faded, and it sank into a red fireball. That night, Shindai and the others lived in a simple inn, but it was much cooler here than in Tokyo, so they had a good night's sleep.Everything will have to wait for the news collected tomorrow. After Jindai woke up in the morning, he wanted to go around the island again.This time I don't want to disturb others.Call a taxi and head south according to yesterday's itinerary.However, there was no gain.At the dawn of Chichang in the lava field, I once got off the car to visit the special scenery here.There was no one.The lava field near the open-air bath on the right cannot see fishermen, and it is a desolate and lonely scene.When I asked the driver, the answer was the same as what the criminal police said yesterday. Except for people from the nearby fishing village who came occasionally, no one used this open-air bath.There are also hot springs on the west coast, so there is no need to come to such an inconvenient place. What a pity, it would be terrible if this were in Tokyo.East Criminal Police said while wiping his sweat. When they returned to the inn for lunch, two detectives from yesterday came to report to them. Reports from all the small villages were collected. On the morning of the 15th and 16th, no yachts docked, nor were there any witnesses. Although it was a half-expected answer, Jindai and Dong were still very disappointed. In other words, there was no sign of the yacht at all?God asked. No, someone saw the yacht in the race.Between 8:30 and 11:00 in the morning on the 16th, fishing boats at sea saw sailing yachts, some sailing south and some sailing east.Of course the times vary, probably because the yachts in the race are spread out to sail.However, no one saw the yacht parked on the shore. 14 After the yachts participating in the competition set off from the oil pot, they gradually dispersed when they reached the sea of ​​Miura Misaki, and then they could not see each other's sails.That's what the people in the yacht club say.Therefore, the Sea Bird driven by Shibamura and Ueda was obviously caught in the racing yachts seen by the fishing boats, and circled the island for half a circle. Dongjun, it seems that there is more and more hopelessness.After the local criminal police went back, Jindai said. Oops.East Criminal Police frowned and said. However, looking at your face, it doesn't look too bad. You don't have a pessimistic expression either! Well, that is to say, neither you nor I have been disappointed. Yes, I am not disappointed, I still have confidence.And you?Mr. Jindai? Well, try again anyway, there should be a loophole in Shibamura, although all the information we have collected is unfavorable, but I feel more and more that there should be a problem. Yes, it seems seamless, but there are still flaws.All fiction must have flaws.This flaw must be found. Instead, the eyes of the two lit up.They had to be at the airport twenty minutes before to catch the 3:30 plane, but they left the hotel just after one.First go to the General Administration to thank the director, and then take the car to the airport.The road passed the lava field again. No matter how you look at this kind of scenery, it feels very rough and desolate. Other places are full of emerald green mountains and blue seas. Only here is a large piece of dark brown lava, which looks like hell. And it extends all the way to the sea, so this feeling is even stronger.There is indeed a gloomy feeling. After passing Sandhama, which has an open-air bath, you will arrive at the airport. Jindai and Dong walked directly to the front of the counter. May I ask, among the passengers who flew from here to Haneda on the 16th, did anyone buy a one-way ticket?After proving his identity, Jindai asked. After investigation by the service staff, the answer was: Among the forty passengers, only five bought one-way tickets.Almost all the tourists from Tokyo buy round-trip tickets, and the tourists on the island who go to Tokyo also buy return tickets at the same time. Few people buy one-way tickets. When we further investigated the five passengers who only bought one-way tickets from the island to Haneda, it was found that four of them were locals with clear identities.The other one is from Tokyo, named Yasuo Tanaka, aged twenty-seven. What kind of person is this? Please wait a moment. The information registered in buying the ticket is: I live at No. △△ Higashi Nakano, Nakano District, my occupation is a grocer, and my liaison office is my wife’s name. This is a ticket registered at the transportation company in Ikebukuro.The waiter explained. Remember what this guy looked like? Ah, don't remember.Because 20 minutes before takeoff, the guests came all at once.Very busy.The plane only stopped for half an hour. The person named Yasuo Tanaka exchanged the ticket for a registration voucher while he was in a hurry, right? It is not uncommon for guests in Tokyo to buy one-way tickets and fly back to Haneda from the island.Take a boat when you come, and take a plane when you go back. There are changes in this kind of tour. The airport attendant seemed to be saying it defensively because he wasn't paying attention to the man. Yasuo Tanaka may be Shibamura, it's a pity that the airport attendants don't remember his appearance, but they are about the same age.After leaving the counter and sitting in a chair in the waiting room, the East detective said. Well, the only one whose identity cannot be confirmed now is this person. I think I have to go to the traffic commune in Ikebukuro and ask the person who handles the ticket.Kamiyo opened the collar of his shirt and said. The plane flew over the sea lined with small islands and returned to Haneda. After returning to the Metropolitan Police Department to report, it immediately rushed to Ikebukuro.Fortunately, we arrived five minutes before the traffic commune closed. Yasuo Tanaka did come here on August 14th to book an air ticket, two days earlier than August 16th. The person in charge of the reservation said: I don't remember his face anymore, because there were a lot of guests that day, and that person was wearing dark sunglasses. Both Jindai and Dong said many characteristics of Shibamura to remind each other's memory, but the person in charge scratched his head and replied: It doesn't look like this, but I don't remember what it looks like When registering the ticket, the name Yasuo Tanaka, as well as the address and liaison office were filled in very smoothly. Did the guest write it himself?God asked. The person in charge took a look. Huh?This is my word.Ah, I remembered, the guest’s right index finger and middle finger were bandaged and injured, so he couldn’t hold a pen, so he asked me to write it for him. He said, I’ll fill out the form for him, but I don’t remember his face. .The person in charge tilted his head again, and said strangely. After walking out of the traffic commune, East Criminal Police said: It's strange to hide the handwriting, and wear dark sunglasses to prevent people from seeing the face, and the age is a few years younger.However, Yasuo Tanaka must be Shibamura. I think so too. The two went to Nakano, and with the assistance of the traffic police, they looked for the Higashi Nakano △△, the grocer, and Yasuo Tanaka.As expected, there was no house number with this number, and there was no grocer named Tanaka nearby. The two went into a nearby shop to drink beer. The weather in Tokyo was sweltering. After sitting down in a corner with no customers, Jindai said: However, even if Yasuo Tanaka is Shibamura, why was he able to return to the oil pot on the Sea Bird at 1:30 p.m. on the 17th?This is still a mystery. Well, I've been thinking about this too, how about I tell my imagination?東有些害羞地說：芝村從羽田換機到京都，當天晚上到飯店屋頂，一聲不響的把妻子美彌子帶走，沒有讓曾根晉吉發現，美彌子的屍體是在東京曾根晉吉家附近找到的，其搬運方法之謎，這裡暫且別說，先考慮芝村，他為了要駕駛海鳥號回油壺，只有當天晚上從京都伊丹機場坐飛機到羽田，不然就是翌晨搭早班飛機飛到羽田。那個時間海鳥號應該正朝著油壺方向在海上航行，船上只有上田伍郎一個人。不過，芝村要回航行中的船上，唯有從直昇機吊下去。 直昇機？ 也就是說，芝村回到羽田後，立刻坐上事先預約的直昇機，讓直昇機把他送回海上的遊艇。 神代微笑著點頭。 很有趣的想像，但缺乏真實性。 老實說，我自己也這樣想。 Isn't it?坐直昇機的話，回海鳥號的事就洩漏了，總不能把直昇機駕駛員和公司職員的嘴巴全部堵住。再說，直昇機低低飛在船上面的話，其他遊艇上面的人也會看到，詭計就被揭穿了。 話雖如此，第二天他們兩人仍然不氣餒，儘管在三宅島沒有掌握到線索，他們卻愈來愈相信十六日下午八點多，芝村出現於正在觀賞大文字點火的京都飯店屋頂，強行帶走美彌子。 他們假定芝村從三宅島搭乘三點半起飛的飛機，而調查供他轉機，從羽田至伊丹的飛機時間。有一班下午五點的飛機，這班飛機於下午五點四十五分抵達伊丹機場，然後坐計程車，從名神高速公路到京都的飯店，約需一個鐘頭，那麼，六點五十分就可以進入飯店玄關了，與觀賞大文字點火的時間剛好配合。 芝村到屋頂，在黑暗中找出美彌子，從美彌子背後的特徵，要認出她一定不難。芝村拍拍妻子的肩頭，美彌子回頭一看，活像看到幽靈，嚇呆了，連氣都不敢喘。 芝村默默催促她離開，曾根晉吉的背部就在她的眼前，卻一句話也不能對他說。她恰似受到蛇攻擊的青蛙，跟著丈夫下樓，她為了不讓丈夫捉到她和曾根晉吉通姦的事實，連留在飯店房間的皮箱也不敢去拿。 當天晚上芝村帶著妻子回東京，美彌子大概臉色蒼白，虛脫般地跟著丈夫走吧。從時間表看來，有一班午後九點從伊丹飛往羽田的飛機，四十分鐘後還有一班，反正芝村押著妻子，搭乘其中一班飛返羽田。 這時候，芝村心中可能充滿了對妻子復仇的快感。 在羽田下飛機後，坐計程車進入東京都內，這時美彌子在丈夫面前始終戰戰兢兢吧？不論丈夫探取怎樣的行動，無疑的她在害怕之餘，陷於半失神狀態。丈夫不說話，想必是已發現她和曾根晉吉的關係。 芝村一句話也不提妻子和曾根晉吉的關係是聰明的，因為他一旦說出來，美彌子就絕不會順從地照他的話做吧。 應該駕著遊艇在海上航行的芝村，為什麼突然出現於京都的飯店屋頂？可能最初芝村對美彌子說，遊艇比賽中途發生問題，臨時取消，所以立刻到京都來找妳，幸好在這屋頂找到妳，我東京還有事，一起回東京吧。然而，回東京以後，芝村以不說話表示他什麼都知道吧。美彌子唯有緊張顫慄而已。 到這裡為止，神代和東的想法相同。 15 然而，接下去的推理就遇到了困難。 芝村駕著海鳥號回到油壺是事實，而且當時他疲倦到昏倒的程度，這也是有目共睹的。 東刑警雙手支著頭說，雖然他想出直昇機的說法，但自己也知道那是沒有現實感的想像。 這時候，神代的思想忽然停在芝村自己說的海鳥號的故障是發生在相模灣這句話。推理恰似在空中迷路的蝴蝶，隨便停在就近的一朵花上面那樣。 喂，根據剛才的假定，芝村用怎樣的方法雖然還不知道，但他是不是在回程到相模灣海上時，讓帆檣翻折，害死上田伍郎？ Well, yes.東看著下面抱著頭說。 不過，還是有疑問。 怎樣的疑問？東抬頭注視神代的嘴角問。 假定芝村為了永遠不讓人知道他曾登陸三宅島，搭機飛往羽田而製造帆檣翻折的事故，害死上田伍郎，那麼，應該在離開真鶴海角更遠的外海。 因為離海岸遠，比較安心。但事實上芝村說，海鳥號發生意外的地點是相模灣附近，比東經一百三十九度三十分的直線上偏西的一百三十九度十一分的海上。 東點點頭，表示不錯。 真鶴海角的突端大約一百三十九度十分，也就是說，非常接近芝村的遊艇發生意外的地點。據芝村說，是因為操舵失誤才偏到西邊去。 不過，據遊艇俱樂部的人說，芝村的技藝相當不錯，這樣的人在返航途中，航線錯誤，而且操舵也失誤到造成帆檣翻折的程度，簡直不能相信。所以，海鳥號故意離開其他遊艇的航線，以便謀害上田伍郎的嫌疑很大。 你的意思我已經明白，可是，真鶴海角十七日上午沒有人看見遊艇靠岸。而且你也知道，調查過航行中的船隻，同樣沒有人看見遊艇接近真鶴海角。 是的，問題就在這裡。神代閉上眼睛。 他想，問題確實是在真鶴海角，攝影雜誌翻開的那頁刊載的題名真鶴海角之晨那張照片，有一個人往海那邊而去。而且據拾柴老婦說，有一個穿褐色短袖襯衫的男人，手持釣竿往崖下的小路而去，怎麼不能認為十七日上午芝村同樣走這條路往崖下而去。 兩人沉默了許久，各自在腦中為命案的復原而設法組合。 神代終於先開口說： 芝村的海鳥號既沒有在三宅島靠岸，也沒有在真鶴海角靠岸。這一點我們已經看過雙方的海岸，沒有疑問。三宅島方面沒有人的地方是斷崖絕壁，船隻無法接近，可以靠岸的港口卻有漁村。我們看見的熔岩海岸雖然人少，船卻不能接近。另外，真鶴海角南端是絕壁，岩礁多，沒有遊艇可以駛入的地方我們一直認為海鳥號在三宅島靠岸，芝村從那裡登陸，這想法錯誤，芝村是從船上跳入海中。 跳海？ 可能是在船接近三宅島大約三、四十公尺的地方，芝村就跳入海中，游水上岸。那附近人少，而且離機場不遠。 東刑警連忙翻開地圖問： 那一帶呢？ 三宅島的機場近，而且沒有人，船又可以接近的海岸，就是佐田海角北面那荒涼的熔岩海岸吧？ good.東注視著地圖思考了一會兒，那麼，芝村是把身上的衣服脫下來放在遊艇，游上岸的嗎？ 不能吧，穿著衣服不能游泳，而且芝村回到油壺時，和啟程時穿著相同的衣服。 不過，芝村出現於京都的飯店時，一定穿得整整齊齊吧？那是在什麼地方穿戴的？ 大概是三宅島。 三宅島？ 東君，除了在京都的飯店以外，在那以前，從三宅島的機場坐飛機到羽田，也不能穿游泳衣吧？ 也就是說，與出現於京都的時候相同的衣服？ should be. 那麼，他一定有共犯，這共犯在熔岩流海岸等候他，讓他脫下游泳衣，換上西裝嗎？ 沒有共犯，這是本案最奇妙的地方。 你認為是芝村單獨幹的？ 我是這樣想。 不過，如果芝村有共犯，那就方便多了，我們一直沒有辦法解決的一個疑問就可以解決了。 你是說，芝村為什麼知道十六日晚上妻子要和曾根晉吉投宿京都的飯店？ 對，芝村因為發現了這件事，才能想出這天衣無縫的不在場證明。假使有共犯，知道美彌子和曾根晉吉京都之行的秘密，事前就告訴芝村，那麼疑問就解決了。 共犯為什麼能知道美彌子和曾根晉吉的秘密約會？ 就算共犯跟踪美彌子或曾根晉吉到京都，看到他們進入那家飯店，要打電話通知芝村。但當時芝村已經駕著遊艇出海了，美彌子是送芝村出海後才到京都去的。 不錯，即使有共犯在，也無法知道美彌子和曾根的秘密約會，當然跟踪後也不能通報。東深深點著頭回答。 東君，我相信芝村沒有共犯，他是單獨做案的。神代丟掉已短的香煙說：上田並不算共犯，從某方面來說，海鳥號繞過三宅島至相模灣發生意外的地點為止，上田一直是芝村的協助者。因為上田不知道芝村謀害美彌子的計劃，所以只能算是協助者。 上田做為芝村的協助者，扮演了怎樣的角色？ 首先，他協助芝村讓遊艇靠近三宅島的某處我們的推測是熔岩流海岸，使芝村跳入海中，然後上田單獨操舵，把海鳥號駕到回程的航線上。 Then what? 唔，老實說，再下去就不清楚了，這一部份是包括芝村到京都，帶美彌子離開飯店，再回東京，以及如何回到海上的遊艇。 芝村怎樣說服上田伍郎做他的協助者？據你的推測，芝村沒有把殺妻計劃告訴上田吧？ 芝村不會向上田透露的。神代的語詞突然轉為緩慢。 那麼，他如何說服上田？ 要從三宅島坐飛機去東京的行程，大概會說，但要往返京都的計劃是否告訴上田，就不得而知了。不過，一定約好要重返在海上朝油壺回航的遊艇。理由不難找到，要讓其他同伴們大吃一驚的說法可能最婉轉。當然光是說說，上田不見得會答應。上田是薪水職員，芝村有的是錢，所以可能還是利用金錢讓上田協助他吧 好，到芝村登陸三宅島搭飛機為止的協助可以了解，那麼，芝村是如何回到航行中的遊艇上？ That's the problem.神代以手掌拍拍額，搖了兩三下頭：這是我最感頭痛的地方。 於是，東刑警接下去說： 神代兄，芝村在十六日深夜，帶著美彌子從京都回到東京，是嗎？當然他本人不承認，但除此以外沒有更合理的解釋。 good. 那麼，如果十六日晚上芝村在東京的話，他可以在殺害美彌子，埋了她以後，再到真鶴海角去嗎？ Oh yes. 所以，芝村可能悄悄躲在林中過了一夜，因為是夏天的晚上，不怕受涼。 Not bad. 然後，就像真鶴海角那拾柴老婦說的，芝村從崖上走那彎彎曲曲的小路下去。因為事先和上田說好了時間，所以上田會把遊艇駛近。芝村就從下面的岩石跳入海中，游泳回遊艇。其後兩人共同操舵，將遊艇駛回航線。 um, um.接下來芝村就單獨操舵，讓上田站在計劃好的位置，故意造成操舵失誤，帆檣翻折，主桅桿就把上田打落海中大概是這種情況吧。 依照你的推測是這樣，但在三宅島時，如何把船上的衣服換成西裝？而且在真鶴海角時，非把西裝換回原先的衣服不可。這些是怎麼做的？再說，真鶴海角並沒有發現芝村遺留的衣服。還有，穿西裝時也需要穿皮鞋。 凡是會駕駛遊艇的人，游泳技術都很高明。芝村大概也一樣。據我的推測，我是認為芝村從船上跳入海中時，西裝、襯衫、領帶、皮鞋、襪子是以塑膠袋密封，繫在頭上游到海岸去。所以他不是穿游泳衣游泳，而是穿內褲，打赤膊。 Ah not bad.東表示同感。 在三宅島的熔岩海岸附近登陸後，立刻拆開頭上的塑膠袋換衣服。這個時候，上田操舵的遊艇應該離開海岸很遠，在海上比賽的航線上。換上西裝後，芝村就以東京來的觀光客姿態到機場去。 登陸的地方沒有人，但走到機場的路上，不會被當地的人看見嗎？ 這一點尚未調查，我們委託三宅島的警察調查的，只是有沒有人看見遊艇靠岸而已。因此，沒有人的熔岩海岸的可能性最大，那裡到機場大約只有兩公里吧？ 是的，差不多。 再一次委託三宅島的警察調查十六日下午兩點至三點半之間，是否有人看見走過那一帶的紳士時，也許會出現目擊者。但也許印象不深也說不定。因為從東京方面來的釣友很多，觀光客也不少 說到這裡，神代的語調變得很緩慢，聲音也轉小。東刑警正感到奇怪而看著神代臉上時，神代突然睜大眼睛說： 對了，是真鶴海角那個穿褐色短袖襯衫的男人！ 褐色短袖襯衫？ 就是拾柴老婦看見的男人。老太太說，看見那男人一手拿著釣竿，一手提著深藍色包包，日期是十七日，時間是上午八點左右 其原因呢？ 褐色短袖襯衫和深藍色包包，一定是芝村的變裝。他從三宅島海岸的船上跳入海中時，塑膠袋內除西裝外，還帶著這褐色襯衫。一件短袖襯衫和一頂登山帽不會增加太大的體積，這塑膠袋可以繫在頭上。 從京都回羽田後，正如你所說，芝村帶著美彌子坐計程車，到曾根晉吉家附近，趁著黑夜絞殺美彌子，當場掩埋。行兇後，拿著事先預備的釣竿，到路上攔計程車到橫濱去。再另換計程車去真鶴町，故意在街上下車，步行到海角去。因為在深夜坐計程車直接到海角是不自然的行為。在街上下車，司機會以為是家在那附近。當夜芝村在海角的林中度過，或在那賣橘子的小店內過夜。 在那裡脫下西裝和襯衫，換上褐色短袖襯衫？ 對，還有那頂灰色登山帽。灰色與褐色遠看時和斷崖的顏色差不多，不容易引人注目。芝村連這一點都計算在內。黑色長褲則沒有改變。 Well, not bad. 那位拾柴老婦不是說，她看見那男人一手持釣竿，另外一隻手提著深藍色包包嗎？老太太以為包包裡面是便當，其實是脫下來的西裝。 Ah, so it is. 八點多，事先約好由上田操舵的海鳥號從三石的海那邊來了。芝村脫下短袖襯衫、帽子、長褲，收入包包內，再以塑膠袋嚴密的封好，頂在頭上，以一條內褲跳入海中，游回離岸不遠的遊艇。 釣竿拋入海中吧？ 一定的，釣竿會隨波逐流，登山帽也許同樣拋入海中那身釣魚者打扮，是為了被人看見時避免引起懷疑吧。 芝村回到遊艇後，穿上原先脫下來留在船上的衣服，自己到船尾去操舵。到了適當的地點時，說些什麼話，讓上田伍郎站在帆檣剛好會被擊中的地方，恰當地讓帆檣翻折，殺害上田伍郎。 我想，這些推測大體上沒有錯。神代說完，東刑警深深吐了一口氣，這實在是策劃細密的大詭計，前所未有的利用空間和時間，相互配合，巧妙地證明當時本人不在殺人現場。 是的，這是以前從沒有人想過的詭計。 到這裡為止，一切經過完全明白，然而，問題是如何獲得證據。 三宅島沒有人看見遊艇靠岸，真鶴海角也沒有人看見芝村從崖下的海邊游泳到遊艇。這兩個地點是目擊者的死角。當然這也要有幾分幸運，萬一這兩個地點之一在當時出現漁船，看到海岸附近有遊艇，那詭計就出現破綻了。不過，芝村的計劃當然是對準可能性最高的地點而進行的。 現在尚有兩個問題，其一是十六日下午五點以後，大阪行從羽田起飛的飛機，是否有叫做田中安雄的乘客？其二是同日下午九點半以後，從伊丹飛往東京的班機中，是否有一對身分不明的男女乘客？ 向航空公司詢問的結果，沒有田中安雄這個姓名。接著，索取這兩種航次的乘客名單，由搜查員們分別一一打電話調查，查出其中有六人是假名。客機的安全性增加以後，已不把意外事故放在腦中的乘客，稍有原因，就和投宿旅館一樣，不登記真實姓名。 芝村和美彌子顯然是這六人之一。神代瞪著那六個不明身分的人名說。 十六日下午五點的大阪行全日空班機中有一對男女，當夜九點四十分由伊丹飛往東京的日航班機也有一對男女。 年齡方面，大阪行的男性五十二歲，女性二十七歲。晚上回程的男性三十二歲，女性二十六歲。 大概是回程這對男女，住址不同，但我想是芝村和美彌子。表格一定是芝村在機場的櫃枱填寫的。下午五點大阪行那班，剩餘的乘客之中，應該有芝村才對。 芝村一定和在池袋的交通公社預約時一樣，右手指綁著繃帶，由櫃枱的人填寫。所以調查起來比較容易。 神代同意東刑警的想法，立刻向全日空詢問。 果然有這樣的人。羽田機場在十六日下午五點大阪行的飛機將要起飛時，這個人才抵達。這班飛機向來乘客不多，隨時可購到座位。 長相是不記得了，但記得是戴著墨鏡。 這位櫃枱人員唯一記得是，那個人中等身材，穿著西裝。 接著，兩位刑警到日航，委託他們以電話向伊丹機場詢問。據說，在飛往東京的飛機起飛前不久，一個右指頭帶傷的男人請櫃枱負責人代筆填寫男人和女人的姓名。這兩方的男人名字都不是田中安雄，名字各自不同。女方當然也不是美彌子。 怎樣才能使芝村和這指頭綁繃帶的人一致？ 神代和東都努力思考，只剩下最後一步而已。 由於櫃枱負責人不記得面貌，給他看照片或者見面都無法指認。換句話說，與沒有目擊者一樣。 這時候，早先就在進行的計程車方面的調查已經出現了結果。十六日午後十點以後，沒有任何計程車載送可能是芝村與美彌子的男女到美彌子遇害的現場附近。假使他從大阪回到羽田機場，應該會利用機場前面的計程車。因而向當夜在那裡候客的全部計程車調查，結果沒有一位司機記得這樣的人。 再說，芝村在殺害美彌子之後，猜測是先回家拿釣竿，再坐計程車赴真鶴海角。故調查那時段在他家附近載客往真鶴海角的計程車，但也沒有任何線索。考慮到也許中途再坐車的情形，而擴大範圍調查，結果仍然相同。即使不記得面貌，拿著釣竿的乘客應該會留在司機的印象中。 假使說，芝村是在往真鶴海角的路上才購買釣竿，但深夜店已關，清晨則尚未開門。事實上詢問過真鶴海角的釣具店，毫無結果。 這樣看來，芝村是利用自用車？但若是這樣，則自用車必須停在羽田機場。且到真鶴海角，回遊艇後，棄置的車非被人發現不
