That's a striking cover on this late detective pulp from Columbia. As usual, editor Robert Lowndes has assembled a good-looking pulp with some very good authors inside, even on a low budget. In this case, that group includes Richard Deming, Robert Turner, Seven Anderton, Thomas Thursday, and Richard Brister. Those guys are nearly always worth reading.
UPDATE: Lowell Wilson points out this cover is a swipe from Ray Johnson's cover for CHARLIE CHAN CARRIES ON. I assume that Johnson did this SMASHING DETECTIVE cover, as well. I've seen several mentions of Johnson's work lately. He was an excellent cover artist.
