Night fell over the manor. Candles guttered in the hallway. A scream cut the silence. Footsteps hurried toward the library. They found his body sprawled. Eyes open, staring at nothing. Blood darkened the Persian rug. A note tucked beneath fingers. Ink bled along jagged script. Detective Marlowe crouched, flashlight shaking. He whispered a name, unheard. Storm windows rattled with accusation.
