Bill Minto is a world-weary property developer. His marriage is on the rocks. His health is failing. His cut-cornered projects constantly threaten to come back and haunt him. So when a mysterious caller offers him the job of a lifetime - all he must do is excavate the hidden tunnels under a country house-he jumps at the chance. But it soon becomes clear Bill is not alone in the tunnels. A past he"d long believed hidden lurches after him in the darkness, smelling blood. And guilt.
