The storm arrived at midnight. It shook the old mansion's windows. A single light burned upstairs. A shadow crossed that window. Then the light suddenly went out. Silence followed the thunder's retreat. The butler climbed the grand staircase. He carried a silver tray. He found the library door. It was slightly ajar, strange. He entered the dark, cold room. Lord Blackwood sat in his chair. He did not move or speak. A red stain spread slowly. The butler dropped the tray. He screamed into the storm's return.
