The lighthouse keeper was found dead at dawn, his lantern still burning beside the cold, overturned chair on the cliff. The inspector arrived by boat through thick fog, carrying photographs, notebooks, and questions nobody wanted to answer for the town. Every window in the village stayed shuttered while gulls circled silently above roofs slick with rain and gathering darkness tonight. Somewhere inside the keeper cottage, a clock ticked loudly, marking time for secrets nobody dared confess aloud before the storm. The inspector pushed open the door and whispered the victim name, hoping the silence would finally break before nightfall came.
