Heavy rain lashed against the frosted glass of the library windows while thunder shook the ancient manor to its foundation. Lord Harrington sat completely motionless behind his polished mahogany desk, staring at the ceiling with wide, cold, and lifeless eyes. A silver letter opener projected cleanly from his chest, staining his crisp white silk shirt with a dark crimson pool. Detective Miller slowly knelt beside the fallen aristocrat, carefully picking up a single scorched ivory chess piece from the floor. Every heavy oak door remained bolted securely from the inside, meaning the ruthless killer was still trapped inside this mansion.
