Rain stitched the dark harbor to the black November sky. Detective Mara Voss found the body beneath the old pier. A silver compass was turning inside his frozen left palm. The rising tide had erased every step except one scar. Mara tasted copper fog and heard the old town lie. Somewhere the church bells counted witnesses who refused to wake. She pocketed the compass and followed its bright needle north. Behind her the harbor lighthouse blinked twice then went dark.
