The rain lashed against the tall manor windows as the heavy clock chimed once for the dead man inside here. Lord Harrington sat slumped over his mahogany desk while a single drop of ink stained his pale and lifeless hand. Cold wind howled through the open casement, fluttering the expensive curtains like the ghosts of a long forgotten winter past. Nobody heard the muffled gunshot roar because the thunder drowned out every sound within the dark and silent study tonight. Inspector Thorne entered the room with heavy steps, his sharp eyes scanning the shadows for the killer lurking near him.
