The rain-slicked cobblestones gleamed under flickering gaslight as Detective Clara Hayward arrived. A single, crimson rose lay near the body with no fingerprints or any other clues. The victim wore a silver locket engraved with initials “E.L.”, but it held no photograph. Clara knelt, noticing faint tire tracks leading toward the alley’s shadowy, dead-end wall. A clock tower chimed eleven, yet the time of death remained stubbornly, frustratingly unknown. Her partner, Inspector Royce, whispered that the butler had vanished just moments before the scream.
