In 1942 Jack Nissenthall, a radar expert and the son of Jewish refugees in England, volunteered for a suicidal mission. He agreed to join a five-thousand-man combat team on a surprise landing at Dieppe in occupied France. His own special assignment was to penetrate a key German radar station on a cliff high above "Green Beach," the code name for the landing area. To find out how it operated was essential to Allied plans for D-Day. The soldiers who accompanied him had a different mission : make sure Jack Nissenthall didn't fall into German hands - at any cost. -- From the book jacket.
