Rain tapped on dark glass. The grandfather clock struck midnight. Lord Blackwood held his chest. Poison burned through his veins. His crystal goblet shattered below. Red wine stained white wool. The study door clicked shut. Heavy footsteps faded away softly. The dying man gasped twice. Silence fell over the room. A gloved hand pocketed keys. The killer vanished into shadows.
