If you like movies that take place on trains, you might get a kick out of this Columbia programmer, in which a wide cast of characters become the usual suspects when murder is committed on an L.A. to San Francisco sleeper. Ben Lyon and Barbara Weeks make attractive leads, and some of the supporting players (Ethel Kenyon, Dwight Frye) are interesting to look at. Less successful is Tom Dugan's "comic" bit as a drunk who for obscure reasons attaches himself to the newspaper reporter hero outside a phone booth in Union Station and makes a general pest of himself. Rather below the standard set by Warners for this genre of picture, but entertaining nonetheless, and about 90% of the picture takes place on the train itself, for which Columbia had provided quite nice sets.
