Rain hammered the cobblestones as detectives arrived at Willow Manor. The grand foyer glimmered with crystal, masking a sinister secret. A shattered vase lay beside a crimson-stained antique rug floor. Officer Hayes whispered, “Someone killed Lord Whitmore before midnight here.” A single fingerprint glistened on the brass candlestick, evidence waiting. The clock struck thirteen, echoing ominously through the marble corridors.
