Tulkinghorn is found dead in his office by Mr. Clamb, shot through the heart. Inspector Bucket quickly concludes that it's murder, committed by someone who knew him. Clamb points the finger at Sgt. George. Word quickly spreads to the Dedlocks and Mr. Smallweed, who also points the finger at George. Sir Leceister offers a reward of 100 guineas. George however denies shooting him and says he saw a woman in a black veil outside Tulkinghorn's offices. Esther's friend Caddy has given birth but is ailing. Ada calls on Mr. Vholes to find where Richard is staying. She finds him in miserable lodgings devoting himself full-time to the case. He does attend Ada 21st birthday dinner but is clearly unwell.
