A historical novel that opens in Europe in 1941, during World War II, with the introduction of a German secret agent, Hans Farber, following a successful mission in Leningrad, Russia. His superior and head of the Abwehr, Admiral Canaris, charges Hans with a nigh-impossible task: assassinate the prime minister of Britain, Sir Winston Churchill, at the rendezvous point between that political leader and the president of the United States, Franklin D. Roosevelt.
