La sombra del lobo

In his ninth and last appearance as retired jewel thief Michael Lanyard-aka The Lone Wolf-the peerless Warren William again finds himself overseas helping to battle the Third Reich. This time, he and loyal valet Jamison (the priceless Eric Blore) arrive in Egypt, where Lanyard is promptly blackmailed into stealing vital documents that the Nazis need.

A decent Lone Wolf entry finds our hero sent in a wild goose chase by nazi spies, and gets involved with a femme fatale, thread in coded message, informers, and devious villains and that in an exotic locale. It's familiar and standard, yet really fun, thanks to the smooth plot, Eric Blore and the debonair Warren William who makes smooth and dashing a work of art.
