The moon hung low over the silent old Victorian mansion. Inside, the wealthy widow lay sprawled on the marble floor. Blood pooled beneath her silver hair and her diamond necklace. Inspector Brown knelt beside her pale and lifeless cold body. The clock in the hallway struck twelve ominous heavy strokes. Three guests stood silently watching from the darkened open doorway. The detective noticed fresh mud upon the polished black shoes. A single red rose rested upon her cold white chest. No murder weapon was visible anywhere in the grand room. Someone must have entered silently through the unlocked garden door.
