Rain hammered the conservatory glass as Detective Marlowe arrived late. The victim lay sprawled beneath prize-winning roses, perfectly still now. Blood had soaked into dark soil, delicate petals scattered nearby. Lady Whitcombe insisted nobody left the manor during the storm. Marlowe noticed muddy footprints leading toward the locked kitchen door. The butler held a silver tray, hands trembling visibly uncontrollably. Someone had extinguished the hallway candles moments before the scream. Marlowe smiled grimly, knowing every guest was lying blatantly tonight.
