The fog clung thickly to the cobblestones, obscuring the lanterns’ glow as the clock struck midnight with eerie precision. A muffled scream pierced the silent alley, echoing off damp brick walls before vanishing into the night’s embrace. Detective Harlan Whitmore adjusted his hat, his breath forming clouds in the chilled air as he knelt beside the body. The victim’s wide, glassy eyes reflected the flickering lamplight, their lips parted in a final, unanswered question no one would hear. A single silver locket lay clutched in their stiffened fingers, its delicate chain broken like the life it once adorned. Whitmore’s gloved hand hovered over the locket, sensing the secrets it held would unravel a web of deadly lies. The killer had left no footprints, no trace beyond the lingering scent of rosewater and something far darker.
