129

Conan's class receives a new student named Ai Haibara. After school, a boy named Toshiya asks the Junior Detective League to find his missing brother. The Junior Detective League along with Ai investigate Toshiya's house and finds a painting of Natsume Sōseki. Toshiya reveals that before his brother disappeared, a woman, who had an interest in that portrait, approached Toshiya. The Junior Detective League search around town to ask whether anyone has seen the woman or Toshiya's brother. Conan notices that a man was using a counterfeit ¥1000 and realizes Toshiya's brother was kidnapped and forced to help create counterfeit bills. After following the man along with the clues Toshiya's brother left behind, they are able to apprehend the organized crime group and save Toshiya's brother. On the way home, Ai reveals that she betrayed the Black Organization and escaped with the use of the APTX 4869 which caused her to become a child. She reveals that she accidentally sent a floppy disk containing data on the Black Organization to her sister which is now in the possession of her sister's professor, Masami Hirota. Agasa takes the two there to retrieve it only to realize that Hirota has been murdered. The suspects are Hirota's three students who visited that day. Conan reveals the culprit to be Akira Shirokura; Shirokura after bludgeoning Hirota to death tied the answering machine cassette tape around the key to the room which rewound when a call was made and subsequently bringing the key into the room. As evidence, Conan reveals that Shirokura's fingerprints should be found on the tape. Ai breaks down and asks Conan why he could not save her sister, Akemi, from the Black Organization. Later that day, Ai attempts to read the files off the disk only to have a virus delete all the data. (Source: Wikipedia)
