Rain tapped aggressively against the dark windows of Blackwood Manor. Inside the study, Lord Harrington slumped over his mahogany desk. A silver dagger protruded sharply from his torn silk vest. Crimson blood dripped slowly onto the unfinished, handwritten last will. The grandfather clock chimed midnight with a slow, eerie echo. Detective Miller quietly stepped through the unlocked heavy library door. He adjusted his wet trench coat and scanned the room. A broken teacup lay scattered beside the smoldering stone fireplace. Muddy footprints led directly from the corpse toward the window. The ruthless killer was clearly still somewhere on the grounds.
