Pygmalion follows the adventures of phonetics professor Henry Higgins as he attempts to transform cockney flower girl Eliza Doolittle into a refined lady. The scene in which Eliza appears in high society with the correct accent but no notion of polite conversation is considered one of the funniest in English drama. Like most of Shaw's work, Pygmalion wins over audiences with wit, a taut morality, and an innate understanding of human relationships.

This volume also includes Major Barbara, which attacks both capitalism and charitable organizations, The Doctor's Dilemma, a keen-eyed examination of medical morals and malpractice, and Heartbreak House, which exposes the spiritual bankruptcy of the generation responsible for the bloodshed of World War I.
