The Twenty
A tense novel from a fast-rising star, Sam Holland, The Twenty fuses a chilling race-against-time with blood-curdling crime fiction.
When DCI Adam Bishop arrives at the crime scene in the dead of night, the sight of the body is bad enough—but what Adam notices next chills him to his core. More bodies surface. And the spray-painted numbers daubed above the corpses reveal the horrific truth: the killer is counting down. But to what end?
Adam has no idea—until Dr. Romilly Cole knocks on his door with damning evidence pointing to a series of murders fifteen years earlier—a case she knows intimately from her past. Now it's personal—and the next knock on his door could be fatal.
