Anglo-Irish novelist and playwright whose subject is the leisure class of her native Ireland.

Born into the Anglo-Irish gentry (the daughter of an estate owner and the poet Moira O'Neill), Keane was educated by a governess. She began to publish novels while in her 20s, under the name M.J. Farrell. She later said, “Young men would have been afraid of you if they thought you could read, let alone write.” Keane used her sharp eye and mischievous wit to satirize the personal intrigues and pursuits of the leisure class, to which she herself belonged. She especially delighted in describing its passionate obsession with horses and foxhunting. Her first novel, The Knight of Cheerful Countenance (1928), was followed by Devoted Ladies (1934) and several other novels of the same tenor. The success of her comedy Spring Meeting (1938; written with John Perry) led to a career as a playwright. Treasure Hunt (1950), also written with Perry, was another success; Keane turned it into a novel (1952). Her insights into the genteel occupations of the rural gentry, however, fell out of step with the literary output of the times, and this, coupled with the untimely death of her husband, kept her silent for about three decades.

Using the name Molly Keane, she returned in 1981 with the acclaimed novel Good Behaviour, in which an unattractive, unloved woman murders her domineering mother. Time After Time, a novel about four handicapped siblings, was published in 1983 (filmed 1985). Keane's later novels include Loving and Giving (1988; also published as Queen Lear) and Conversation Piece (1991).
