The Citadel

by A. J. Cronin · 1937

The Citadel, published in 1937, follows the career of Andrew Manson, a young Scottish doctor who begins his practice in a poor Welsh mining community. Drawing on A. J. Cronin’s own experience as a medical inspector, the novel portrays Manson’s idealism, his struggle against quack remedies and inadequate medical education, and his pioneering research on lung disease among miners. As he moves from the valleys to London, Manson confronts professional corruption, material temptations, and a personal crisis that forces him to reassess his values. The story is a powerful critique of medical ethics and social inequality, and it is credited with influencing the creation of Britain’s National Health Service.
