This is a typically suspenseful and well-made Ed Dmytryk film, starring the urbane Warren William as 'the Lone Wolf'. It is the ninth in that series. As usual, William is accompanied by his butler Jameson, played by the truly wonderful Eric Blore, who is such a delight to watch as he camps up his subservience. The script is well done, the tension is there. Scenes where William has to retrace his steps through the London streets blindfolded, counting how many steps after each turning, and listening for key sounds, are very ingenious. The villains are villainous, as they should be. (One is an early appearance by Forrest Tucker.) Those dastardly Nazis, they are always trying to destroy London, but William will stop them, if the police would only leave him alone and stop trying to arrest him for something he hasn't done. Being a double-agent is no fun, especially when your 'control' has been killed in the Blitz and there is not even anybody left to 'deny' you. Good stuff, really good stuff. Oh yes, and there's Hilary Brooke as the looker, not bad!
