Synopsis by Mark Deming
Peter Lorre stars as the famous Asian detective Mr. Moto in this remake of Murder in Trinidad, in which Moto is asked to help the United States government crack a smuggling ring bringing in stolen diamonds from Puerto Rico. Moto's deductive powers quickly prove impressive as he matches wits with the slow-minded gangster "Twister" McGurk (Warren B. Hymer). This was Lorre's seventh film as Mr. Moto; he would make one more before the series was retired at the end of 1939. Originally shown as Mr. Moto on Danger Island.
