Thunder rattled the frosted glass windows of Blackwood Manor while rain lashed mercilessly against the stone walls outside the library. Lord Harrington lay completely motionless upon his velvet armchair, an antique silver letter opener protruding sharply from his bloody chest. A single crystal tumbler of amber scotch sat beside an unsigned will across the dark mahogany desk near the corpse. Detective Miller adjusted his wet wool coat, knelt beside the body, and carefully examined the dead man's cold pale hands. Clutched tightly within the stiffened fingers was a torn photograph showing seven smiling faces beneath an ominous red ink circle. Nobody could have entered through the heavy locked oak doors, yet the killer was undoubtedly still hiding inside the house.
