Detective Conan - Episode 1165

After the murder of chess player Kishitani Naoto in the Nishi-Topia building, Conan deciphers the victim's bloody clue: A knight keychain pressed onto a chess magazine points toward the king's side (jap. Ogasawara), indicating Ogawara Kinji as the culprit. Ogawara, a tournament participant himself, previously staged an attack on himself in the waiting room to create an alibi.

Conan reveals the trick:

- Ogawara used a Prince Rupert's drop ("Dutch tear") to shatter his glass by deliberately twisting a modified pen.

- Two identical glasses cases in the trash served to transport the glass objects.

- His "crossbow attack" was faked by firing a detached bolt tip into his own bag.

Ogawara's motive is revenge for the suicide of chess player Saso Ryoichiro, whom Kishitani drove to ruin a year earlier through a trap involving the ringtone "Amazing Grace." Ogawara lured Kishitani into the toilet, shot him with a crossbow, and stole his phone to cover up the deception.

In parallel, Kuroda Hyoei reveals to Conan a connection to the unsolved case of US billionaire Amanda Hughes, who was murdered 17 years ago during a chess tournament. Her dying message—a cryptic code with a chess piece—resembles Kishitani's clue. Kuroda was a spectator in the same hotel and remembers Amanda, her Japanese bodyguard Asaka Rachel, and the shogi master Haneda Koji, who taught Amanda chess.

The episode ends with a threat: RUM (Black Organization) identifies Wakasa Rumi as suspicious via surveillance cameras and orders her elimination. Chianti and Korn position themselves in the rain for the shot, while Wakasa—whose right eye is in pain—exits the building.
