When Jim and Laura Pepperman find a musty German Olympic jacket

and an old journal in their attic, they stumble onto a gripping

pre-World War II story of a cousin Jim knows nothing about.

After a career-ending injury forces Hans Pepperman to lose his spot on the 1936 Olympic boxing team, he trades his athletic aspirations for a degree in mechanical engineering and secures his dream job working for the famous Willy Messerschmitt. Tasked to solve the stalling issues of the BF109 fighter plane engine, Hans finds himself smack in the middle of the Abwher Intelligence Service's radar. Pro-Germany but anti-Nazi, he reluctantly agrees to help flush out the spy leaking secret information on the BF109 engine to foreign agencies . . . and finds himself a suspect of espionage and murder. Unsure who to trust, he must unravel the tangle of lies he's caught in before he falls prey to the Nazi agenda slowly and stealthily taking over the country he loves.
