Never aired on Turner Classic Movies
13 May 2009 | by kevinolzakSee all my reviews

One of the few entries never aired on Turner Classic Movies, this average feature was helmed by Edward Dmytryk, who followed it with another Wolf "Counter-espionage" (1942), "Confessions of Boston Blackie" (also 1942, with Chester Morris), "The Falcon Strikes Back" (1943, with Tom Conway), and "Captive Wild Woman" (also 1943, with John Carradine). A topical story with Inspector Crane (Thurston Hall) guarding gems that will help pay for a foreign nation's fight for liberty, and asking Michael Lanyard (Warren William) for his expertise on methods of theft that could possibly be used. Aboard the ship being guarded, there is a spy (John Harmon) who tips off his confederates as to what's going on. The entire gang kidnap Lanyard's manservant Jamison (Eric Blore), believing him to be the Lone Wolf and expecting him to aid them in pulling off the heist. Some amusing byplay with Lanyard pretending to be Jamison, and the police always on the wrong trail. A rather dull cast this time around, with Victor Jory a standout as the gang leader, 'Dapper' Dan Streever, and unbilled Ian Keith in a miniscule part as another gang member, Six O'Clock Sam. From 1939-1943, Warren William would appear in nine Lone Wolf entries (only three left after this one) with seven features remaining overall (including his next "The Wolf Man") before he died of multiple myeloma in 1948 at the youthful age of 53.
