Catherine: A Story was the first full-length work of fiction produced by William Makepeace Thackeray. Thackeray's original intention in writing it was to criticize the Newgate school of crime fiction, exemplified by Bulwer-Lytton and Harrison Ainsworth, whose works Thackeray felt glorified criminals. Thackeray even included Dickens in this criticism for his portrayal of the good-hearted streetwalker Nancy and the charming pickpocket, the Artful Dodger, in Oliver Twist. Ainsworth's Jack Sheppard portrayed a real-life prison breaker and thief from the eighteenth century in flattering terms. In contrast, Thackeray sought out a real-life criminal whom he could portray in as unflattering terms as possible. He settled on Catherine Hayes, another eighteenth-century criminal, who was burned at the stake for murdering her husband in 1726.
