Rain fell hard on Manor. Lights flickered inside the house. Someone screamed from the library. Detective Hale arrived immediately after. He wore a black coat. The body lay near fireplace. Blood stained the wooden floor. No weapon was ever found. Guests whispered among themselves nervously. The night hid many secrets.
