Patricia Highsmith (January 19, 1921 – February 4, 1995) was an American novelist and short story writer, known for her psychological thrillers, which led to more than two dozen film adaptations.
 Her first novel, "Strangers on a Train", has been adapted for stage and screen numerous times, notably by Alfred Hitchcock in 1951.
 Highsmith wrote 22 novels, including her series of five novels with Tom Ripley as protagonist, and many short stories.
 Existentialism is the literary movement that most influenced her writing, with "Dostoyevsky and Gide through Camus and Sartre" among her favorite authors.
 Graham Greene described Highsmith as "the poet of apprehension rather than fear.
 Fear after a time...is narcotic, it can lull one by fatigue into sleep, but apprehension nags at the nerves gently and inescapably."
 Published under the pseudonym of "Claire Morgan," Highsmith wrote the first lesbian novel with a happy ending, "The Price of Salt", republished 38 years later as "Carol" under her own name.
The Two Faces of January (1964) is a psychological thriller novel by Patricia Highsmith.
 Its title alludes to the two faces of the Roman god Janus, after whom the month of January was named.
 Biographer Andrew Wilson, in his 2003 publication "Beautiful Shadow: A Life of Patricia Highsmith" claims the title is 'appropriate for the janus-faced, flux-like nature of her protagonists'.

 Amini has worked as a screenwriter since the early 1990s.
 He was nominated for numerous awards for the 1997 film "The Wings of the Dove", including an Academy Award for Best Writing – Adapted Screenplay.

Purple Noon (Original: Plein soleil) (Italian: "Delitto in pieno sole"), (aka "Full Sun", "Blazing Sun", "Lust for Evil" and "Talented Mr. Ripley"), is a 1960 French-Italian film directed by René Clément, loosely based on the 1955 novel "The Talented Mr. Ripley" by Patricia Highsmith.
 The film stars Alain Delon in his first major film, along with Maurice Ronet (as Philippe Greenleaf) and Marie Laforêt (as Marge); Romy Schneider appears briefly in an uncredited role as Freddie Miles' companion, and Billy Kearns (an expatriate American actor well liked in France) plays Greenleaf's friend Freddy Miles.
 The film, principally in French, contains brief sequences in Italian.
The Price of Salt (later republished under the title Carol) is a 1952 romance novel by Patricia Highsmith, first published under the pseudonym "Claire Morgan".
 Highsmith—known as a suspense writer based on her psychological thriller "Strangers on a Train"—used an alias because she did not want to be tagged as "a lesbian-book writer", and because of the use of her own life references for characters and occurrences in the story.
 Though Highsmith had many sexual and romantic relationships with women and wrote over 22 novels and numerous short stories, "The Price of Salt" is her only novel about an unequivocal lesbian relationship and its relatively happy ending was unprecedented in lesbian literature.
 It is also notable for being the only one of her novels with not only "a conventional 'happy ending but in which her characters also had "more explicit sexual existences".
