peter lorre give one of his most evil performance a the owner of the titled place . the plot have a new government agent be put on the track of peter lorre character . when the g man contact his kill by one of lorre agent and the g man be send to prison for the kill even though everyone know there be more to the story . lorre have the man parole into his care and bring to his island where he be mine diamond . lorre want to know what our hero know and but he isn not talk and a battle of will be set in motion . this be a good solid little thriller that doesn not quite make a great deal of sense plot wise and but even so the film hold your interest . i have put the film on last night in order to use it a something to drift off to and instead i find the tale riveting enough i be up an extra 70 minute . lorre be the reason that one fall into this . his quite demeanor be unnerve . he do very little but it clear from his order and the way everyone react to him ( watch how they light his cigarette ) that he be a bad dude . worth a look if you should run across it .
