Rain hammered the old manor windows as midnight slowly approached. A scream tore through the hallway and then died suddenly. Detective Marlowe found the lifeless body beside the cold fireplace. Blood stained the Persian rug under the victim's outstretched hand. Every guest claimed innocence while hiding secrets behind polite smiles. The locked library door suggested someone knew the house well. Outside, thunder masked footsteps that vanished into the dark garden.
