Detective Miller stood beside the crimson velvet ropes while staring at the lifeless body lying on the cold marble floor. The brass pocket watch lay open nearby upon the rug while its shattered glass reflected the terrible truth hidden inside. The weary inspector adjusted his worn tweed coat before stepping carefully around the dark crimson stains spreading across the tiles. A silver letter opener rested near the fireplace mantel while holding faint traces of fresh blood on its polished handle. He understood instantly that this was no ordinary robbery gone wrong because the expensive jewelry lay untouched on the table. The victim wore a torn silk dressing gown while a single red rose rested gently against his still cold chest. Inspector Croft knelt down to examine the dark pool while noticing a cryptic message scratched directly onto the wooden floor. The shallow letters spelled out a warning that only the dead could ever truly understand before departing quietly into forever. Heavy rain continued drumming against the glass while washing away fresh footprints leading out toward the empty alley gently below. He stood up slowly and retrieved his leather notebook while preparing to question the weeping housekeeper in the main hall.
