It is 1944 and weeks before D-Day. The Allies are disguising their invasion plans with a phony armada of ships and planes. Their plan would be ruined if an enemy agent found out . . . and then The Needle – Hitler’s prize undercover agent, a cold and professional killer – does just that. Hunted by MI5, he leads a murderous trail across Britain to a waiting U-Boat. But he hasn't planned for a storm-battered island, and the remarkable young woman who lives there.
