The harbor bells rang twice before dawn while Inspector Mara Voss found the body cold and motionless beneath the pier. A silver cufflink glinted near the victim's hand and its enamel crest matched the yacht club across the black bay. Rain softened the footprints on the planks yet one deep heel mark pointed toward the locked red cedar boathouse door. The dead man was Adrian Vale a retired magistrate whose smile had ruined fortunes from Blackwater Harbor to Port Sable. Mara noticed lavender on his sleeve though the tide carried only diesel brine and smoke from the gray morning ferries. Inside his pocket lay a train ticket punched for midnight and a key wrapped in altar linen from the chapel. Then the foghorn answered the bells and every window along the waterfront went dark as if rehearsed by someone nearby.
