Cashel Byron's Profession is George Bernard Shaw's fourth novel. The novel was written in 1882 and after rejection by several publishers it was published in serialized form in a socialist magazine. The novel was later published as a book in England and the United States. Shaw wrote five novels early in his career and then abandoned them to pursue politics, drama criticism and eventually play writing. The Admirable Bashville (1901), a short play based loosely on this novel, was written to protect American copyrights after the novel became unexpectedly successful in the United States.
