Rain hammered the cobblestones as dusk swallowed the town quietly. Detective Marlowe arrived, trench coat dripping, eyes scanning for clues. A shattered window framed a silhouette of a trembling figure. Footsteps echoed, then silence—an ominous sign of impending doom within. Inside, the chandelier swayed, casting shadows over blood‑stained carpet floor. A scream shattered the night, echoing from the locked study.
