Plot
Charlie Chan has been investigating the whereabouts of Allen Colby, heir to a vast fortune. He recently made contact with his relations in San Francisco: his Aunt Henrietta Colby Lowell, her daughters Alice and Janice, and Janice's husband, Fred. The story opens as Allen is traced to a ship that has sunk, but it cannot be confirmed that he is dead. On the contrary, evidence is found that someone is trying to kill him to prevent his return to San Francisco to claim the estate.
Allen arrives at Colby House and is promptly murdered. His body is revealed in the course of a seance conducted that evening at Colby House with Chan in attendance. He is an old friend of Mrs Lowell; who, like her late brother, is a devout believer in psychic research. She has retained the services of Professor Bowen and his wife, Carlotta, who is a medium. Someone subsequently attempts to kill Mrs Lowell and eventually appears to succeed. The truth is revealed in another seance, at which the murderer makes a foolish mistake.
