Joseph visits Gray and attempts to blackmail him to keep quiet about his body-snatching operation. Gray tells Joseph the story of the infamous murderers Burke and Hare, and reveals that they procured bodies for Dr. Knox, MacFarlane's mentor. Gray promises to pay Joseph, but smothers him to death when the other man allows him to get too close. Later, he delivers the body to MacFarlane's lab as a "gift". Meg Camden (Edith Atwater), MacFarlane's housekeeper and secret wife, tells Fettes that Gray admitted to robbing graves during the Burke and Hare trial to shield the real perpetrator - MacFarlane. Later, MacFarlane offers Gray money to stop tormenting him. Gray refuses to take the bribe, and vows that the doctor will never be rid of him. Enraged, MacFarlane beats Gray to death.
