Letters on Demonology and Witchcraft

In ill health following a stroke, Sir Walter Scott wrote Letters on Demonology and Witchcraft at the behest of his son-in-law, J. G. Lockhart, who worked for a publishing firm. The book proved popular and Scott was paid six hundred pounds, which he desperately needed. (Despite his success as a novelist, Scott was almost ruined when the Ballantyne publishing firm, where he was a partner, went bankrupt in 1826.)
