On 12 February 1828—the only exact date Burke quoted in his confession—she was invited into the Hares' house and plied with enough alcohol to ensure she was too drunk to return home. After murdering her, Burke and Hare placed the body in a tea-chest and sold it to Knox.[44] They received £10 for each body, and Burke's confession records of Simpson's body that "Dr Knox approved of its being so fresh ... but [he] did not ask any questions".[45] In either February or March that year an old woman was invited into the house by Margaret Hare. She gave her enough whisky to fall asleep, and when Hare returned that afternoon, he covered the sleeping woman's mouth and nose with the bed tick (a stiff mattress cover) and left her.
