The heavy velvet curtains parted slowly to reveal the silent, lifeless body slumped across the antique mahogany desk at midnight. A single crimson drop stained the ivory blotter while the grandfather clock struck twelve with a deep, haunting rhythmic tone. Detective Elias Thorne stepped inside, his polished boots clicking against the cold marble floor as he scanned the dark room. Outside, the freezing rain lashed against the tall cathedral windows, masking a faint sound of footsteps near the back hallway. Who could have committed such a brutal deed within this locked mansion when all the guests were gathered downstairs partying?
