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. ~ Mark Deming, Rovi
