Thick fog rolled slowly across the silent, moonlit country estate. Inside the study, a single grandfather clock chimed midnight ominously. Lord Blackwood slumped forward across his heavy mahogany writing desk. Dark crimson blood dripped quietly onto the expensive Persian rug. An antique silver dagger remained buried deep inside his back. Cold winter wind rushed through the shattered French terrace doors. Muddy footprints led away into the dark and rainy garden. A terrified maid screamed loudly upon discovering the gruesome sight.
