Case Closed: Episode 40 English Dubbed Episode Description: Reika Gilmore, daughter of billionaire Robert Gilmore, is having a birthday party and invites Richard who brings Rachel and Conan, as a special guest. The party abruptly ends when some guests discover the tires on their cars had been slashed, forcing Donald Hilbler, Micheal Stewart, Quinten Mifune, Dirk Copeland, Steve Sloan, and house maid Nonee to spend the night. Reika goes to change clothes, but is never seen again and Quinten mentions an accident that was promised to not be spoken of. The group splits up and searches for her, but Conan and Richard find Steve drowned to death in the fountain, and the still missing Reika is to blame. To calm everyone's nerves, Nonee and Rachel volunteer to make tea. Rachel sips hers, 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 Steve's murder: Sonya, Nonee's granddaughter, drowned apparently with no life vest, attempting to save Reika and Steve after they got caught in a storm which left them stranded on an island. During the night, a power failure occurs, Rachel is nearly drowned to death, and Richard believes that a serial killer is amongst them, randomly attacking the guests. Rachel 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. Donald makes coffee but spills it on Conan and Richard, prompting them to go wash in the bathroom, only to find Reika drowned to death in the bathtub.
