The Lone Wolf continues, with a new face.
The Lone Wolf, Michael Lanyard (now played by Gerald Mohr) has returned from the war and immediately gets drawn into a plot to steal a valuable diamond. Inspector Crane (William B Davidson) naturally thinks Lanyard and Jameson (Eric Blore) stole the gem - Crane is quite an unimaginative detective to be honest as he always thinks Lanyard is behind all gem thefts, maybe he thinks he will get it right finally. The gem was stolen from a dancer who was wearing it, the dancer being murdered. Lanyard must track down the gem and the murderer...
The Lone Wolf series was just starting to run out of steam by now. Post-war, these kinds of bright and breezy B-movies were starting to look a bit dated in the coming age of the Noir, however Mohr slightly refreshes the role. The rest of the Lone Wolf formula is there and this is a good, if unexceptional, entry in the series.
