Rain battered the shuttered manor. Inside, twelve guests awaited supper. Only eleven heard the scream. Clara dropped her silver spoon. The butler appeared without knocking. His gloves were strangely wet. Nobody asked about the stains. Upstairs, Lord Ashcombe lay motionless. A dagger pinned his necktie. The bedroom window stood open. Dust covered the untouched sill. Clara recognized the ivory handle. She had buried it yesterday.
