The Three Clerks (1857) is a novel by Anthony Trollope, set in the lower reaches of the Civil Service. It draws on Trollope's own experiences as a junior clerk in the General Post Office, and has been called the most autobiographical of Trollope's novels. In 1883 Trollope gave it as his opinion that The Three Clerks was a better novel than any of his earlier ones, which included The Warden and Barchester Towers.
