The harbor bell rang twice before dawn while Inspector Mara Voss found the lighthouse keeper dead beside his warm lantern. Rain salted the windows and every gull vanished from the rocks as if the whole town itself had swallowed them. Mara noted black mud on the threshold pearl buttons missing one cuff and a ledger open to yesterday's unrecorded tide. The victim's pipe lay cold yet embers scented the room with cloves rum ink and something sharper than winter brine. A photograph faced downward near the stove showing four men laughing though one face had been scratched to bare silver. Then footsteps crossed the pier below and Mara pocketed the key before the door confessed it had never been locked.
