After nearly collapsing under the pressures of poverty, loneliness, and an addiction to Dexedrine, Spark sought help for her drug use and began to work seriously on a first novel, The Comforters (1957), partly with the financial and emotional support of the novelist Graham Greene. Though a late fiction writer, Spark began producing novels and stories at a rapid pace. In 1961 she wrote The Prime of Miss Jean Brodie, widely considered her masterpiece. The novel follows a teacher at a girls' school who carefully and manipulatively cultivates the minds and morals of a select handful of promising pupils. In 1969, it was adapted into an Academy Award-winning film starring Maggie Smith and was a Royal Command Performance.
