The old manor stood silent beneath the moon's pale glow. Detective Mara Shaw arrived late, her coat damp with rain. A single lamp flickered inside the drawing room's broken window. The front door hung open, creaking softly in cold air. She stepped inside and smelled copper, old wood, wet stone. A body lay by the hearth, hand stretched toward ashes. Blood pooled beneath the victim's head, dark as spilled wine. Mara knelt, careful not to disturb the scattered playing cards. An ace of spades rested inches from his left shoe. She frowned, noticing the victim's pocket watch was strangely missing. No keys, no wallet, no sign of forced entry anywhere. The phone line had been cut cleanly with sharpened steel. Then she saw the message written in ash on stone. It read only four cold words: "He knew too much."
