A murder that defies logic—and a killer on the loose.

England, 1176. Aelred Barling, esteemed clerk to the justices of King Henry II, is dispatched from the royal court with his young assistant, Hugo Stanton, to investigate a brutal murder in a village outside York.

The case appears straightforward. A suspect is under lock and key in the local prison, and the angry villagers are demanding swift justice. But when more bodies are discovered, certainty turns to doubt—and amid the chaos it becomes clear that nobody is above suspicion.

Facing growing unrest in the village and the fury of the lord of the manor, Stanton and Barling find themselves drawn into a mystery that defies logic, pursuing a killer who evades capture at every turn.

Can they solve the riddle of who is preying upon the villagers? And can they do it without becoming prey themselves?
