Rain poured heavily against the tall glass windows of the grand library while the antique grandfather clock struck twelve times. Lord Harrington sat motionless across his mahogany desk, an ornate silver dagger buried deeply into his richly embroidered velvet coat. Dark crimson blood slowly pooled across the unfinished manuscript, quietly soaking the urgent confession he had desperately struggled to write. Detective Miller stepped silently through the unlocked French doors, shaking cold rainwater from the wide brim of his wool hat. Nobody inside the locked manor could have escaped outside, meaning the ruthless killer still remained hidden among the terrified guests.
