Chapter 13 — The Strange Person Finding Murder Case

A woman named Hirota Masami shows up at Kogoro's (Richard's) Detective Agency and asks him to find Hirota Kenzo, her father. Rearranging Kenzo's cat's name, they realize it's the name of a racing horse. They find him at a horse track but the next day, Kenzo is found dead and Masami is missing. Conan remembers that he accidentally placed a tracker on Masami but the batteries in his glasses run out. Another detective is discovered who is tracking Kenzo down for his client Hirota Akira. After Conan's glasses are recharged, they head to Masami's location and find Akira dead. Conan realizes that the Hirotas are connected to a billion yen robbery and that a disguised Masami passed them in the hall. Conan follows her and finds her with her boss, Okita. Okita reveals Masami's real name to be Miyano Akemi and that she, along with the two murdered men, stole the money. Okita plans to remove all evidence of his involvement and prepares to shoot her but is knocked out by Conan. Akemi confesses that she left the money at the hotel and thanks Conan for his help.
