And only now an the story begins in April 1944. A wounded American,  with detailed knowledge of D-Day plans falls into Nazi hands. With Allied victory at stake, he must be found. Disguised as an SS officer, Martineau is soon swept into a deadly game of bluff and counterbluff- his opponet none other thank Field Marshal Rommel, the Desert Fox himself!
