The fog curled through Riverside Street, muffling footsteps and secrets. The clocktower struck midnight, casting long shadows over cobblestones tonight. In the harbor tavern, a violin sighed, then silence returned. A body lay beneath flickering lamps, eyes fixed on chandeliers. The widow whispered names, while the room held anxious breath. Detective Mara entered quietly, pocket notebook ready, questions unsaid yet. Every face wore mourning like perfume, masking guilt beneath smiles. Tonight, a scream would fracture the night and reveal truth.
