"Billy Boyle, a young Irish-American cop from Boston has just made detective - with a little help from his cop relatives and friends - when World War II breaks out. His rabidly anti-English family calls on his mother's distant cousin, Mamie, married to a general, to wangle a staff job for him far from the fighting. But instead of a "safe, cushy" stateside assignment, he is ordered to London, still undergoing the Blitz. His "Uncle Ike" is Dwight D. Eisenhower, plucked from obscurity to command Army forces in Europe, and he wants Billy to be his personal investigator."
