Cold November rain beat hard against the high library windows. Lord Reginald sat slumped over his massive mahogany writing desk. A silver letter opener was buried deep in his chest. Thick crimson blood dripped slowly onto the expensive Persian rug. The grandfather clock struck midnight with a long, eerie chime. Inspector Miller stepped inside the room, shaking his wet coat. He noticed two half-empty brandy glasses resting on the table. Someone had shared a final drink with the dead gentleman. A faint scent of lavender perfume lingered in the air. The killer was definitely still hiding somewhere inside this mansion.
