A fierce storm raged outside while a silent killer watched from the dark shadows of the large drawing room tonight. Detective Miller stepped inside and saw the body lying on the cold stone floor near the dying, dark fireplace grate. She wore a red velvet dress that was stained with fresh blood from a deep, fatal, open knife wound tonight. No one else was in the grand house when the terrible crime happened here in this very quiet, dark room.
