It's 1942, and George and his older brother, Jack, are spending a restless wartime summer in Whitby, Ontario. Their mom is working at the local munitions factory while their dad is off fighting the Germans in Europe. One afternoon, the boys stumble across Canada's top-secret spy camp, and so begins an exciting and terrifying adventure as George and Jack get caught up in the covert activities of Camp X.
In the most exciting summer of their lives, George and Jack find themselves enlisted in the fight against the Axis. And they learn a frightening and important lesson: in war, everybody is under suspicion ... including themselves.
Fascinated by Camp X and its secrets, the boys begin to suspect local townspeople of being spies. Is the police chief keeping tabs on people for enemy purposes? Is Jack's boss at the newspaper really amassing information for sinister reasons? The boys actually meet the master, William Stephenson, the Man Called Intrepid.
Besides being a rollicking good adventure, readers will learn a little more of the fascinating world of spies, and a little of Canada's roll in training the spies of World War II.
