Cold rain battered against the dark windows of Blackwood Manor. Inside the grand library, silence hung heavier than the fog. Lord Harrington now lay motionless across his expensive velvet armchair. A silver letter opener was buried deep in his chest. His pocket watch had stopped precisely at midnight last night. The frightened maid dropped her heavy tray onto the floor. Her sharp scream pierced through the quiet of the house. Nobody heard the killer step out into the dark night.
