Episode 215: The Bay of Revenge (Part 1)
Scenario: While Kogoro, Ran, and Conan are driving near the ocean, their car breaks down, prompting them to ask for help at a house which belongs to famous lawyer Kensuke Tachibana. There, they meet secretary Yuuichi Sakuraba, his caretaker Yaeko Kamei, his wife Yuki Tachibana, his office's accountant Noriko Sugimura, and lawyer Fumio Fujisawa. As the day progresses, Kensuke explains to Kogoro that he’s been receiving threatening letters from someone with the initials “T.K.” Their dog, Yohan, has been acting weird. Kensuke leaves for his fishing trip, while the gang walks Yohan who continues acting strange when a suspicious person is seen riding a boat. Suddenly, Kensuke’s boat capsizes and he drowns to death. They find out that Kensuke was killed by someone with the initials T.K. which later stands for Tatsuya Kumada, who had been sending threats to him. Five years ago, Kensuke acquitted Tatsuya of the murder of a man named Masahiko Tsuruta who was found hung in his house. Tatsuya is believed to be the killer. The investigation team rushes into his apartment and are horrified to find Kumada, their prime suspect, hanging from his ceiling.
While driving on a family trip in Chiba, Kogoro's car breaks down. They stop by a house on the bay, where Kogoro, Ran, and Conan meet the famous lawyer Kensuke Tachibana and his secretary Yuuichi Sakuraba, and later they meet his caretaker Yaeko Kamei, his wife Yuki Tachibana, and his office's accountant Noriko Sugimura and lawyer Fumio Fujisawa. Tachibana is getting threatening letters from a man with the initials "T.K." The next morning, the dog Yohan is acting strangely. Tachibana leaves the house for a fishing trip, while Kogoro, Ran, and Conan walk the dog. It reacts wildly when it sees a suspicious person in a red hat, on a boat. Later that day, Tachibana's boat is found, halfway sinking, and his body is found deep in the ocean.
A local detective and his assistant arrive at the scene, and the man with the initials "T.K." is found out to be Tatsuya Kumada, an old client of the lawyer, and becomes the number one criminal. However, when they go to his apartment, they find him dead, seemingly hanging himself in a suicide. However, the clues say otherwise. Could someone have killed both the lawyer and the client?
