Thick fog rolled silently across the dark moors of Blackwood. Inside the library, Lord Harrington sat completely still and cold. A heavy silver paperweight had crushed his skull from behind. Dark crimson blood pooled onto the expensive Persian rug below. Victoria dropped her silver tea tray with a loud crash. Her terrified scream shattered the quiet peace of the night. The tall grandfather clock struck midnight with a dull ring. A mysterious shadow slipped under the heavy velvet curtains nearby.
