The second novel in the highly praised new mystery series featuring forensic archaeologist Ruth Galloway, a woman who is very intimate with old bones and big trouble.The Janus Stone, the second Ruth Galloway mystery, sees Ruth literally up to her neck in trouble. She's standing in a trench cut into the ground floor of an old Victorian mansion in Norwich once run by the Catholic church as a home for children. Now it is being demolished to make way for a condo development, and because a medieval church was originally on the site, the town council has ordered an archaeological survey before the new buildings go up. And now they won't go up, not until Ruth has finished her investigation, because she's staring at the headless skeleton of a child buried under the imposing front door.
