This is a highly suspenseful, almost Hitchcockian tale, with excellent performances from the stars. Barbara Stanwyck was always excellent in this kind of role; she's better here than in "Sorry, Wrong Number". And Bogart seems truly menacing as the psychotic artist. Also noteworthy is the performance of Ann Carter as Bogart's young daughter. She was a child actress with a very mature and sophisticated quality about her, in fact she reminded me very much of Patty McCormack, who would play the evil Rhoda in "The Bad Seed" several years later. There's never a dull moment in this 99 minute thriller.
