The Last Supper is a case featured in Criminal Case, appearing as the seventeenth case of the game as well as the city of Grimsborough. It takes place in the Financial Center, a district based in Grimsborough.
Chief King sent the player, Jones and Nathan to young woman Daisy Thompson's house after hearing that she was poisoned in her kitchen. There, they collected Daisy's body. After Nathan confirmed that her poison would cause no threat, the player and Jones started the murder investigation. The killer turned out to be the owner and chef of Chez Valentine restaurant, Valentine Montgomery.
Valentine poisoned Daisy by accident when the victim was having dinner with her husband one night at Chez Valentine. Valentine had intended to poison Tobias Sharp, but the waiter unintentionally delivered the plate to the wrong table, poisoning Daisy, who was found dead in her kitchen the next day. Although the murder was an accident, Judge Hall decided thus a murder is a murder, and that her crime was grounds for a 10-year jail sentence without parole.
