When Billy Coke steps onto the streets of London one December evening in 1940, he has no idea he is stepping to his fate. As Hitler's bombers come close to burning the city down, Billy meets the woman who will change the course of his life: Ilse Magnusson, a musician from Norway, but also something more--a spy in training. Escaping the Blitz for three days, she and Billy drive, quarrel, conceal, reveal . . . and fall finally, fully, in love. Now they must part, each to fight the war their own way. Billy, a Canadian Spitfire pilot, to duel with the Luftwaffe over North Africa and the Med. Ilse to return to her conquered country, ingratiate herself with the Nazi elite--which includes her beloved father--and send vital intelligence back to Britain.
