In his sixth investigation, Lieutenant Billy Boyle finds himself in pursuit of a serial killer with a particularly frightening agenda
.
1943: US Army Lieutenant Billy Boyle, an ex-cop who serves as detective for General Ike, is sent to Caserta, Italy, to investigate the murders of two American officers stationed there. The MOs are completely different, and it seems like the officers had no connection to each other, but one frightening fact links the murders. Each body was discovered with a single playing card: the lieutenant’s with the ten of hearts; the captain’s, the jack of hearts. The message seems clear—if the murderer isn’t apprehended, the higher ranks will be next. As the invasion at Anzio begins, Billy needs to keep a cool head amidst fear and terror as the killer calculates his next moves.
