With a case of amnesia, will Billy remember who he is and what is his mission, before more people are killed?

Billy Boyle has been landed in Sicily in advance of the main Allied invasion forces. But when he awakens in a field hospital after suffering a concussion, he has amnesia. He doesn’t know who he is or where he is, much less what his mission is. His only clue is that he possesses a yellow silk handkerchief embroidered with the initial L and a lot of people seem to be eager to get their hands on this talisman.

As Billy gradually recovers his memory, he recalls that he is his Uncle Ike’s personal investigator in the European Theater of War. Before Billy can remember the dangerous task that has been entrusted to him and do his best to carry it out, several people are murdered. Those opposing him include members of various factions of the American Mafia, as well as soldiers of the German and Italian Armies.

Billy finally remembers his name, but to truly resolve the question of his identity he must dig deep into his soul to discover what kind of man he is.
