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?

To escape a lifetime of poverty, mercenary Sir Benedict Palmer agrees to one final, lucrative job: help King Henry II’s knights seize the traitor Archbishop Thomas Becket at Canterbury Cathedral. But what begins as a clandestine arrest ends in cold-blooded murder. And when Fitzurse, the knights’ ringleader, kidnaps Theodosia, a beautiful young nun who witnessed the crime, Palmer can sit silently by no longer. For not only is Theodosia’s virtue at stake, so too is the secret she unknowingly carries—a secret he knows Fitzurse will torture out of her. Now Palmer and Theodosia are on the run, strangers from different worlds forced to rely only on each other as they race to uncover the hidden motive behind Becket’s grisly murder—and the shocking truth that could destroy a kingdom.
