The cold rain hammered relentlessly against the tall windows of old Blackwood Manor as lightning split the darkened sky above. Inside the grand entrance hall, Margaret Ashworth lay completely motionless on the cold marble floor, her glassy eyes fixed upward. A silver letter opener protruded from her chest, its ornate handle gleaming beneath the flickering light of the overhead chandeliers. Detective Sarah Chen stepped carefully around the dead body, noting the strange absence of blood on the expensive Persian rug. The elderly housekeeper had discovered the corpse at midnight, screaming loudly enough to wake every single guest staying overnight upstairs. Six guests had gathered here for the lavish weekend dinner party, and now each one waited nervously in the library. Chen knew that one of them was certainly lying, and that the cold-blooded killer still remained somewhere inside the house. The ancient clock on the mantel struck one, and somewhere deep in the shadows, someone began quietly laughing to themselves.
