Description: Xiaolan saw a quiz in the newspaper. It was organized by a man named Furukawa University. You can go to Kogasawara to see the dolphins in San Francisco. Finally, Conan came up with a secret answer: paper money in the Showa era.

After boarding the boat, Maori met the leader of Morizaki, who used to be a policeman. Morizaki said today is a special day.

When everyone was eating in the restaurant, there was a sudden noise on the deck. Everyone gathered on the deck, and a flag fluttered in the wind against the background at night.

Mr. Whai, the passenger, was very nervous. Then, there was an explosion and a fire broke out at the stern.

When a group of people arrived at the stern, they found a charred body in the fire. Judging from the sweater worn by the body and the gold watch on her wrist, it was passenger Xie Qiang. Conan found traces of special plastic melting on the face of the body, which was used for plastic surgery. Therefore, he and Hattori (who went to Kogasawara to handle a case at the request of Furukawa University) thought that this person had had plastic surgery before.

When Morizaki and Maori went to every room to look for the murderer, only one old man did not show up. The staff said that the old man was called Ye Caisan. Morizaki was taken aback. Ye Caisan was the mastermind of a 400 million yuan bank robbery 20 years ago. Because of his careful planning, he is called the shadow planner. He never hurt anyone in a robbery, but he didn't kill a female bank clerk in that case twenty years ago.

However, when Whale Well confessed the previous case in the restaurant, there was another sound. Whale Well was shot in the arm and fell to the ground. It was actually Xie Qiang who committed suicide. Everything is a mess. Go to this episode and find out!

PS: This episode is full of suspense. It can be said that I didn't know who the murderer was before I saw it. This episode is called Twenty Years of Murder. It turns out that some hatred cannot be erased by time. When the morning sun rises again at the end of the film, it seems that people involved in this case can finally usher in a new day and a new life.

At that time, Furukawa University and Wild Vegetable III were the same person. As long as the wild vegetables are turned 90 degrees three times, it becomes Furukawa University.

Besides, everyone involved in this case seems to be related to water. Did the incident happen at sea, and Mr. Okanagan did it on purpose? (Sakazaki, Whale Well, Xiechuan, Kameda, Shibei, Hailao)
