Between 1928 and 1956, she wrote eleven novels, and some of her earlier plays, under the pseudonym M.J. Farrell. . Her husband died suddenly in 1946 and, following the failure of a play, she published nothing for twenty years. After the death of her husband, Molly Keane sold the big house and estate and moved to Ardmore, County Waterford, a place she knew well, and lived there with her two daughters until she died in 1996. She is buried beside the Church of Ireland church, almost in the centre of the village.
In 1981,Good Behaviour was published under her own name. In fact, the manuscript, which had languished in a drawer for many years, was lent to a visitor, the actress Peggy Ashcroft, who encouraged Keane to publish it. The novel was warmly received and was short-listed for the Man Booker Prize.
