ตอนที่ 39: คดีฆาตกรรมลูกสาวคนรวย ตอนที่หนึ่ง การสอบสวนเริ่มต้น

39

Yotsui Reika, daughter of billionaire Mr. Yotsui, is having a birthday party and invites Kogoro, who brings Ran and Conan, as a special guest. The party abruptly ends when some guests discover the tires on their cars had been slashed, forcing Ichieda Takashi, Gojo Osamu, Mifune Takuya, Rokuda Masashi, Nikaido Yuji, and house maid Nanao Yone to spend the night. Reika goes to change clothes, but is never seen again and Takuya mentions an accident that was promised to not be spoken of. The group splits up and searches for her, but Conan and Kogoro find Yuji drowned to death in the fountain, and the still missing Reika is to blame. To calm everyone's nerves, Yone and Ran volunteer to make tea. Ran sips her tea, feels tired, and soon falls sleep. Conan brings up the accident the group was talking about and believes it may have something to do with Yuji's murder: Nanao Yaeko, Yone's granddaughter, drowned apparently with no life vest, attempting to save Reika and Yuji after they got caught in a storm which left them stranded on an island. During the night, a power failure occurs, Ran is nearly drowned to death, and Kogoro believes that a serial killer is amongst them, randomly attacking the guests. Ran is dazed and it appears her tea was drugged with sleeping pills. Conan finds a few clues and is convinced that the killer is one of the guests staying at the mansion. Takashi makes coffee but spills it on Conan and Kogoro, prompting them to go wash in the bathroom, only to find Reika drowned to death in the bathtub. (Source: Wikipedia)
