The rain drummed softly on the cobblestones as Inspector Grayson studied the body beneath the flickering streetlamp. A silver locket gleamed against the victim’s throat, its delicate chain broken as if torn in a violent struggle. Blood pooled around the woman’s shoulders, stark crimson against her pale silk gown, the fabric torn near the collar. Footprints led away from the scene, deeper into the alley’s shadows, where the darkness swallowed all traces of movement. The inspector crouched, gloved fingers brushing the locket, noting the initials *E.M.* engraved in flowing script beneath the bloodstains. A muffled cough echoed nearby, followed by the hurried click of heels against wet pavement—someone had seen too much. Grayson stood, his sharp eyes scanning the empty windows above, certain the killer had watched from one. The victim’s vacant stare mirrored the moon, pale and unblinking, as the clock tower chimed midnight with hollow finality.
