Fog pressed against the harbor as dawn breathed its secrets. A lone lamp flickered, throwing gold across rain slick cobblestones. From the pier, a bell tolled once and stopped mysteriously. A body lay there, pale beneath drifting cloak of mist. The tide hummed softly, as if listening for a confession. Detective Lior arrived quietly, notebook ready, questions already forming tonight. A gull cried overhead, as if urging someone to speak. Somewhere a radio hissed, reporting nothing but rain and wind. In the shuttered house, whispers stitched clues into silence carefully. Every shadow waited, wanting someone to name the culprit tonight.
