Mary Patricia Plangman was born on January 19, 1921, in Fort Worth, Texas, the only child of the commercial artists Jay Bernard Plangman and Mary Coates, who divorced shortly after her birth.142 Her mother married Stanley Highsmith in 1924, and she took his name; she was raised for long stretches by her maternal grandmother in Fort Worth and moved to New York City as a child.24
She graduated from Barnard College in 1942 and spent the next several years writing comic-book scripts, including romance comics for the companies that later became Marvel.14 Her story “The Heroine” appeared in Harper’s Bazaar in 1945.4 On Truman Capote’s recommendation she spent the summer of 1948 at the Yaddo artists’ colony, where she drafted her first novel.2
Strangers on a Train was published in 1950, and Alfred Hitchcock’s film of it followed in 1951.1 In 1952 she published The Price of Salt, a love story between two women, under the name Claire Morgan, because she feared being labeled a writer of lesbian books; it was reissued under her own name as Carol in 1990.3
The Talented Mr. Ripley (1955) introduced Tom Ripley, a charming con man and killer whom she brought back in Ripley Under Ground (1970), Ripley’s Game (1974), The Boy Who Followed Ripley (1980) and Ripley Under Water (1991).14 The first novel won France’s Grand Prix de Littérature Policière in 1957, and The Two Faces of January won the Crime Writers’ Association’s Silver Dagger in 1964.2
She moved to England in 1963 and to France in 1967, and spent her last years in Switzerland, near Locarno.24 France made her a Chevalier of the Order of Arts and Letters in 1990.4 She died in Locarno on February 4, 1995, at 74, of aplastic anemia and lung cancer, and left her estate to Yaddo.21 Her diaries and notebooks, edited by Anna von Planta, were published in 2021.1
