Hart combines powerful insights into human nature and pristine prose with history and archeology in her stellar fourth crime novel (Publishers Weekly) about an ancient volume of philosophical heresy that provides a motive for murder.

After a year away from working in the field, archaeologist Cormac Maguire and pathologist Nora Gavin are back in the bogs, investigating a ninth-century body found buried in the trunk of a car. They discover that the ancient corpse is not alone--pinned beneath it is the body of Benedict Kavanagh, missing for mere months and familiar to television viewers as a philosopher who enjoyed destroying his opponents in debate. Both men were viciously murdered, but centuries apart--so how did they end up buried together in the bog?

While on the case, Cormac and Nora lodge at Killowen, a nearby artists' colony, organic farm, and sanctuary for eccentric souls. Digging deeper into the older crime, they become entangled in high-stakes intrigue encompassing Kavanagh's death while surrounded by suspects in his ghastly murder. It seems that everyone at Killowen has some secret to protect. Set in modern-day Ireland, The Book of Killowen reveals a new twist on the power of language--and on the eternal mysteries of good and evil.
