The rain pounded against the cold glass window while the grandfather clock chimed twelve times in the dark, empty hallway. Sir Arthur lay motionless upon the Persian rug with a silver letter opener protruding from his silk vest's front pocket. A single glass of expensive scotch sat untouched on the mahogany desk beside a handwritten note smeared with dark blood. Detective Miller stepped carefully over the threshold and sighed deeply while he adjusted his heavy wool coat against the chill. No one heard the heavy oak door creak shut behind him as the shadows stretched long across the study floor. The victim's eyes stared blankly at the ceiling hung with cobwebs, telling a story that only the dead could know.
