Patricia Highsmith was born Mary Patricia Plangman in Fort Worth, Texas, and raised mainly in New York City. After graduating from Barnard College in 1942 she wrote comic-book scripts while writing her own stories and novels, and broke through with her first novel, Strangers on a Train (1950), which Alfred Hitchcock filmed the next year. Her best-known creation is Tom Ripley, the charming murderer of The Talented Mr. Ripley and four more novels.
Her second novel, The Price of Salt (1952), is a love story between two women, published under a pseudonym because of its subject; it was ground-breaking for its positive depiction of a lesbian relationship and its hopeful ending. She moved to England in 1963, France in 1967 and Switzerland in 1982, and wrote 22 novels over nearly five decades.
