Sir Arthur Conan Doyle had connections to Hawick through his maternal grandfather, John Foley. Foley was born and raised in Hawick, and Doyle would visit the town during his childhood. He drew inspiration from the local folklore and history of Hawick for some of his writings, including the "Legend of the Devil's Beef Tub."
