Headlong Hall is the first novel by Thomas Love Peacock, published in 1815 (dated 1816). As in his later novel Crotchet Castle, Peacock assembles a group of eccentrics, each with a single monomaniacal obsession, and derives humor and social satire from their various interactions and conversations. The setting is the country estate of Squire Harry Headlong Ap-Rhaiader, Esq. in Wales.
