The year is 1942. America has, finally, entered the war on the side of beleaguered Britain, bringing to bear its manpower and resources. Winston Churchill has long fought for American involvement, and his dream has been fulfilled. But now comes something to imperil that dream, something with the potential to turn British public opinion against the friendly invaders. American crime, American justice would seem to be straightforward, but the jurisdictional boundaries are crossed, reversed, lost in the maze of murder. An American MP, a Scotland Yard detective and a British officer with close ties to the world of spies and military intelligence together try to unravel the threads, bring murderers to justice. Nothing is straightforward. Neither justice nor retribution. Neither innocence or guilt. The quest takes the three investigators all the way from the British Prime Minister and the American commander, General Eisenhower, to the lowest rungs of the British underworld.
