Double Cross

1943. The British have discovered a Russian spy network operating from the neutral fortress of Switzerland. Ultra, the handpicked elite of British Intelligence, have taken advantage of their knowledge to plant a German double agent there to pass on signals to the Russians. However this perfect double bluff seems doomed to fail when German High Command begins to suspect false play. They plant their own agent in Switzerland to investigate. Only one man has a chance of finding that agent and liquidating him before the secrets of Ultra are blown wide open...one-armed Major Cain and his team of lethal killers.
