Fifty BARs (Browning automatic rifles) have been stolen from a U.S. army base in Northern Ireland. His uncle Ike Eisenhower sends Billy to recover the weapons which might be used in a German-sponsored IRA uprising. Bodies begin to accumulate as Billy finds unexpected challenges to his Boston-Irish upbringing and IRA sympathies. There are rogues on both sides, he learns.

Billy Boyle awakens in a field hospital in Sicily with amnesia. In his pocket is a yellow silk handkerchief embroidered with the initial L. Gradually he remembers: he has been sent ashore in advance of the troops with this token from Lucky Luciano to contact the head of the Sicilian Mafia. But he must also thwart a murderous band of counterfeiters of Army scrip led by Vito Genovese.
