Billy Boyle World War II Mystery

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 message seems clear—if the murderer isn’t apprehended, the higher ranks will be next.
