Chan then informs Lolas guests, who were there to celebrate her engagement, of her death, and brings in two suspects, the psychic and Paul Wagner. Wagner reveals that he was married to Lola, but they had separated. The psychic plays back his conversation with Lola, and reveals himself to be Alfredo Cardozo, the brother of the man Lola killed. Chief Souto asks everyone to stay in the house while the murder is being investigated.Later, Jimmy witnesses a conversation between Lolas butler, Rice, and maid, Lilly. Rice tells Lilly to stay quiet about something she saw earlier. Chan and Souto find scratch marks on the floor where Lola was murdered. Chan suspects that the scratch marks were from the broach Lola was wearing, and that a pin on that broach would still be stuck in the murderers shoe. Chan then finds similar scratch marks under one of the chairs at the dinner table where all of the guests had dined. Jimmy hides in Rices room and finds Lolas jewelry there. He then takes Rice to Chan. Rice explains that he has the jewels but did not kill Lola. Before he can tell Chan who did, the lights go out and he is shot. ........
