509

A child asks the Detective Boys for help on investigating someone who is doing something weird. They are told to come by tomorrow. The next the kid's apartment has been burned down. The only clue to the culprit is the kid's diary, mentioning the yellow guy who argued with the kid's father. Now Conan must solve this mystery while Haibara senses a Black Organization member nearby. After school, Conan receives a phone call from Jodie who tells him that the Black Organization has received a new member codenamed Bourbon. Meanwhile, the Detective Boys receive a request from their classmate, Kaito Suigiura, to investigate the actions of a strange man at his apartment building which his father owns. The next day the Detective Boys find that the apartment has been burned down. The police reveal that all the residents have safely left the building; three people, who were not at home during the fire, are suspected to be the arsonist. The police find Kaito's diary and read Kaito's entry on the day of the fire. The diary mentions three residents and clues: In the morning, the "Red man" will be able to sleep in since it is raining; the "White man" man was able to help him when he fell; the suspicious "Yellow man" returned home at night and was arguing with Kaito's father. They believe the "Yellow man" is the culprit and interrogate the three suspects: Ryuhei Hosoi, a clumsy carpenter who injures himself often; Subaru Okiya, a graduate student who waters the plants of the apartment; and Ginya Makabe, a day trader. The police reveal that Kaito has a collection of model cars and has written Conan's name in his diary as Kuroshiro (黒白?, lit. Black and White). (Source: detectiveconanworld)
