Hey, Peter Lorre gets to play the lead in a movie! And he even gets to be the suave detective, instead of Mr. Moto. Well sort of suave. He's got a cigarette lighter in one scene, anyway.
This is fairly good mid-forties film noir, although I got impatient during some of the flashback scenes. The present day has Sydney Greenstreet and Peter Lorre threatening each other and we're stuck in a flashback watching other people? That's crazy, man! I want more Lorre.
