This is quite an impossible murder mystery, as a desperate girl calls on a detective, but before she has had time to tell him anything she vanishes, he goes after her and finds her, she is persecuted by people who want to kill her, this is proved by an incident in which an innocent old man is gunned down while the shot was aimed at her, the detective offers her his protection and she spends the night in his bedroom with the door locked while he sleeps outside on the sofa with his clothes on, but next morning he finds her strangled, while no one could possíbly have entered her locked room during the night. Those are the facts of this utterly impossible case. Nevertheless, he accepts the challenge and starts digging and finds out all about her intricacies. Three years back she had had a relationship with one of the richest men in the world, a recluse living in splendid isolation on an island off the coast of California with a beautiful wife, allowing no visitors, no interviews, no communications, a worse case than Howard Hughes, but the detective will not give up trying to reach him, even when he is fired at when he accepts an invitation. Great business is involved, the tycoon manages a considerable empire of almost all powerful influence, so he is not to be trifled with. Finally the detective arrives at the truth long before it is revealed to the audience, and the police and FBI take over the case. It's a great script with splendid dialogue while only the music is dreadful.
