A Mortal Terror

In "The Sixth Billy Boyle Investigation," set in 1943, US Army Lieutenant Billy Boyle—an ex-cop and detective for General Eisenhower—travels to Caserta, Italy, to solve the murders of two American officers. With distinct methods and no apparent connection between the victims, a chilling detail emerges: each body is linked by a playing card, suggesting a deadly game is afoot. As the invasion at Anzio looms, Boyle must navigate chaos and danger to catch the elusive killer before more lives are at stake.
