Человек, который умирал дважды

A nightclub singer loses her husband in an automobile accident, and soon afterward witnesses the murders of two narcotics agents, and suffers a nervous breakdown. The police come to believe that all three murders are related, as they had suspected her husband was involved in a heroin smuggling ring, and now they think she may also have been involved in it - especially after they find a large stash of heroin hidden in her apartment.
