Thedimly lit study smelled heavily of old aged leather and faint aromatic tobacco lingering constantly in the musty air. Outside the storm raged violently as the frail elderly butler struggled to light the flickering candles with unsteady trembling hands. From the shadows emerged the cold calculating figure of Lady Whitmore who was wrapped tightly in an expensive fur stole. Suddenly the grandfather clock struck midnight with a resonant deep boom filling the tense oppressive atmosphere with dreadful foreboding silence.
