The Woman from Tangier(1948)

This one has Nylon, an American dancer fleeing Morocco after her employer gets into trouble with the police, and she stops off at Tangiers on her way to Gibraltar. $50,000, in gold, is stolen from the ship's safe and the captain tells the police that the purser was the thief and that he had to kill him in self defense, but the purser must have hidden the money before he got dead. The purser isn't in any position to make a disclaimer. Everybody buys that with the exception of an insurance detective, Shapley, who, along with the audience, suspects the captain of being the thief shows up to investigate further. Written By Les Adams
