The culprit is the woman who claims to be Misato Uehara. The letters on the ring are "M to A", from Misato to Akihiko, since it is Akihiko's ring, not Misato's. However, the culprit thinks that the letters are "A to M", revealing that she is the fake Misato. Her real name is Ikuyo Hasegawa. Ikuyo attempts to drug Conan but is put to sleep. Conan then rescues the real Misato.

Ikuyo's motive is then revealed. She came to kill Akihiko, who fired her because she scammed huge amounts of money from the company. However, she only met Misato, Akihiko's wife, so she intended to use her as a hostage.

Later, the Detective Boys (including Haibara) force Conan to carry all of their book bags home by himself as punishment for "stealing the scene."
