Enjoyable wartime mystery featuring the Lone Wolf as a double agent in London. Ninth in the series, and written in 1942, this entry is directed by Edward Dmytryk (his second in the series). The plot revolves around the theft of plans for a beam device and whether they will be sent to Berlin by a new radio photo transmitter. The Lone Wolf uses sound as the means to learn the secret hide out of the spy ring and scenes of the Blitz are used to show audiences the devastation being doled out on America's British allies. Despite the predictability of the story line, the film is more than a bit enjoyable, and one of the best of the series.
Warren William stars as the suave former jewel thief Michael Lanyard with his faithful sidekick and butler, Eric Blore. Also features Hillary Brooke as the love interest and Forrest Tucker as one of the Nazi spies. Although not credited, it certainly appears that a young Lloyd Bridges also appears albeit with a mustache. If true, he would have had a busy year since he also appears to be listed in over twenty other movies in 1942.
