The fog clung thickly to the cobblestones, muffling footsteps as shadows danced along the narrow alley’s damp walls. A lone figure staggered into view, clutching their chest with trembling hands before collapsing onto the cold, unyielding pavement. Detective Harlan Whitmore knelt beside the body, his gloved fingers brushing the victim’s coat, searching for clues in the dim streetlight. A single silver locket lay open near the corpse, its tiny portrait of a smiling woman now speckled with blood. Whitmore’s jaw tightened as he studied the wound—a precise, deep stab, delivered by someone who knew exactly where to strike. The victim’s eyes, wide with shock, seemed to follow him as he stood, the weight of the case settling in. A whisper of fabric made him turn, but the alley remained empty, the killer already vanished into the unforgiving night. Whitmore pocketed the locket, knowing it held the first secret of many in a puzzle that would test his limits.
