An ancient Irish mystery. A ritualistic modern-day killer. Ireland's first female detective Katie Maguire must find the connection. One wet, windswept November morning, a field on Meagher's farm gives up the dismembered bones of eleven women...Their skeletons bear the marks of a meticulous butcher. The bodies date back to 1915. All were likely skinned alive. But then a young woman goes missing, and her remains, the bones carefully stripped and arranged in an arcane pattern, are discovered on the same farm. With the crimes of the past echoing in the present, D.S. Katie Maguire must solve a decades-old murder steeped in ancient legend...before this terrifying killer strikes again.
