The Black Ace warns his victims ahead when the time will come for them to die. Such is the basic premise of Tomorrow at Seven directed by Ray Enright and scripted by Ralph Spence. Interwoven into this basic premise is a young Chester Morris going to a Mr. Thorton Drake because he knows all there is to be known about the Black Ace. Morris is writing a book, meets a cute secretary that can introduce him, and all the main characters from that point on - including two cops included for protection - board a small plane to go to a huge mansion in Louisiana. All this to escape the ominous note saying Mr. Drake, played indelibly by Henry Stephenson, would die "tomorrow at seven." The old Southern home is reminiscent of the home used in the 1939 version of The Cat and the Canary(also taking place in Loiusiana). This film works because it has a pretty tight and inventive script, some good direction, and good acting. The mystery is not too terribly easy to solve - and though I figured it out - I could never be 100% sure!
