As the winter of 1323 descends on Dartmoor, life has never seemed so bleak to the young priest in his isolated, windswept chapel. It is a far cry from the cathedral cities of Europe of which he dreamed as a novice. So who could blame him for accepting some longed-for human contact and companionship when it is offered by the local miller's daughter, Mary? But when Mary and the unborn child she carried are found brutally murdered, it is obvious where the villagers will point the finger of blame. However, investigators Baldwin Furnshill, Keeper of the King's Peace, and Bailiff Simon Puttock soon begin to have their doubts. It becomes clear that Mary was far from the simple village girl she seemed. What exactly was her relationship with the Squire of Gidleigh, Sir Ralph, who is uncharacteristically grief-stricken at her death? Whatever it was, could it be that he himself was responsible for her death? Or perhaps Osbert, the mill-hand whose love she rejected time and again, could withstand his torment no longer? In their search for the truth, Baldwin and Simon unwittingly put themselves in the greatest danger they have ever faced, and by the time the investigation is over, life for themselves and their families will never be the same again...
