The golden clock struck twelve while the cold rain hammered against the tall glass windows of the lonely manor. Lord Thorne lay dead upon the Persian rug with a silver dagger buried deep inside his pale, thin chest. A single glass of red wine stood untouched on the mahogany table beside the body of the fallen patriarch. Detective Miller stepped inside the room and noticed a faint scent of bitter almonds lingering in the damp air. Five guests waited in the grand hall with trembling hands and eyes that betrayed their dark and hidden secrets. No one had heard a scream despite the fact that they were all staying in the small east wing. The heavy oak door had been locked from the inside, leaving the killer trapped within the silent, stone walls.
