The rain hammered loudly against the cold dark glass pane. Lord Byron slumped over his heavy desk in the library. A single bullet hole ruined his perfectly tailored silk vest. Fresh blood dripped slowly onto the expensive Persian area rug. Eleanor gasped when she saw the heavy silver pistol nearby. Her shaking hands reached out toward the flickering candle flame. The grandfather clock chimed midnight with a sudden mournful ring. Someone moved silently within the shadows of the tall doorway. She felt a cold breeze enter the locked quiet room. The scent of bitter almond drifted through the stagnant air. Eleanor knew that her life would never be the same.
