Billy Boyle is born in Boston. He comes from a long line of Irish policemen. Just when he gets promoted to detective, he is drafted into the Army. There's a war on and every able-bodied man is needed.
Some men are more able than others. Some are just better connected. It turns out that Billy's uncle is Dwight D. Eisenhower, the Supreme Commander - Allied Armed Forces - Europe. Strings are pulled and Billy becomes a commissioned officer and sails for England to join his uncle's intelligence team.
Before Lt. Billy can become acclimated to this new country, yet alone being an U.S. Army officer, he's assigned (whether he chooses it or not) to uncover a spy. A spy who is imbedded somewhere in the Norwegian network that is planning the invasion to recapture their homeland from German occupancy.
Billy's new teammates are a beautiful British WREN officer and her unlikely lover...a member of Polish royalty.
To convolute things further, a Norwegian officer commits suicide. The more Billy investigates, the less he is convinced that the suicide was a well-disguised murder.
