The first installment in RKO's short Dick Tracy series of films in the 1940s. This one sees Tracy (Morgan Conway) working on a case involving a string of murders committed by Splitface (Mike Mazurki). This series was churned out quickly and cheaply. So don't expect an "A" production from them. That being said, it's a thoroughly enjoyable way to spend an hour. Fast-paced, fun detective stories with action and some comedy. Mike Mazurki is a great villain. Conway does fine as Tracy. Lyle Latell plays Tracy's bumbling sidekick Pat Patton. He's the movie's comic relief. Anne Jeffreys plays his Tracy's girlfriend Tess Trueheart. Also an early role for Jane Greer. Give it a shot and I'm sure you'll find it an enjoyable time-killer.
