Shanghai, 1937. It's a confused, chaotic and cosmopolitan kind of town. Local businessman, Fu Manchuria has invited a mixed group to his house to have dinner, but regrettably the host himself will not be present. He's been detained upstairs. Detained by person or persons unknown. He was found in his bedroom, bound and gagged, and with an ivory chopstick through his heart. In short, he's dead. So who killed him? It can only be one of his guests, which means that at least one of you is the murderer. Luckily the private detective Marlowe McClue is here to help you find out who that person is.
