Thunder rattled the dusty windows of the old manor house. Detective Vance stepped into the dimly lit, freezing grand library. Lord Blackwood rested awkwardly upon his expensive red Persian rug. A silver dagger protruded deeply from his motionless, bloody chest. Three frightened suspects waited cautiously outside the heavy oak doors. Vance slowly knelt down beside the wealthy, recently murdered aristocrat. Flickering candlelight illuminated the intricate golden handle of the weapon. A torn piece of parchment rested near the pale fingertips. Someone had scrawled a threatening message using dark crimson ink. The strange note promised further violent retribution before midnight struck. Suddenly, the grandfather clock began chiming loudly in the hallway. Eleven hollow tolls echoed throughout the completely empty, silent mansion. Only one hour remained until another innocent person would die. Vance pocketed the terrifying note and stood up very slowly. The true investigation of this terrible crime had just begun.
