Under the cover of darkness, rain lashed violently against the windows like a warning not yet heeded by assembled guests. The butler, impeccably dressed as usual, noticed the absence of laughter echoing through the normally jovial hall with growing concern. Tall heavy mahogany doors stood sentinel between dimly lit corridors that whispered secrets known only to their ancient wooden frames. Sir Reginald Huntington, the host of tonight's gathering, had always prided himself on hospitality though tonight his smile seemed strained. From the grand staircase, Lady Eleanor surveyed the scene below with eyes that missed nothing of importance in the room.
