The heavy rain hammered against the tall arched library window. Lord Blackwood sat completely motionless in his favorite leather armchair. A silver letter opener was buried deep inside his chest. Dark red blood dripped slowly onto the expensive Persian rug. The grandfather clock chimed midnight with a very hollow resonance. The young maid entered carrying a tray of hot tea. She dropped the silver platter after seeing his pale face. Her loud scream echoed through the dark halls of stone. The killer was still hiding somewhere inside this locked house.
