Your Mission: Find Victor's missing sketchbook by following clues and cracking secret codes. It's a true story of deception: Meet the top secret Ghost Army, a group of artists and sound engineers trained to fake out the Germans in World War II with inflatable rubber tanks and loudspeakers broadcasting the sound of marching troops. And meet real-life Sergeant Victor Dowd, who served in the fight for Normandy, through France, and across the Rhine.
It's a mystery to solve: This hardcover library edition does not include any removable spy tools; a canny reader will unravel clues embedded in the text and illustrations to solve the book's ultimate mystery and experience history in a whole new way.
