Cold rain drummed against the dusty window of the study. Lord Harrington sat slumped over his mahogany desk, utterly motionless. Warm tea steam still floated gently in the chilly air. A broken teacup lay shattered on the expensive Persian rug. Blue poison dripped slowly from his cold, pale lower lip. Inspector Thomas stepped carefully inside the dim, quiet study room. The grandfather clock chimed midnight with a dull, heavy ring. No sign of physical struggle disturbed the otherwise neat room. A golden pocket watch ticked softly inside his stiff jacket. Someone in this grand estate possessed a deadly, secret venom.
