Highsmith was born Mary Patricia Plangman in Fort Worth, Texas. She was the only child of artists Jay Bernard Plangman (1889-1975), who was of German descent, and Mary Plangman (nee Coates; September 13, 1895 - March 12, 1991). The couple divorced ten days before their daughter's birth. In 1927, Highsmith, her mother and her adoptive stepfather, artist Stanley Highsmith, whom her mother had married in 1924, moved to New York City.

In 1955, Highsmith wrote The Talented Mr. Ripley, a novel about Tom Ripley, a charming criminal who murders a rich man and steals his identity. Highsmith wrote four sequels: Ripley Under Ground (1970), Ripley's Game (1974), The Boy Who Followed Ripley (1980) and Ripley Under Water (1991), about Ripley's exploits as a con artist and serial killer who always gets away with his crimes. The series--collectively dubbed "The Ripliad"--are some of Highsmith's most popular works and have sold millions of copies worldwide. The "suave, agreeable and utterly amoral" Ripley is Highsmith's most famous character, and has been critically acclaimed for being "both a likable character and a cold-blooded killer." He has typically been regarded as "cultivated," a "dapper sociopath," and an "agreeable and urbane psychopath." Sam Jordison of The Guardian wrote, "It is near impossible, I would say, not to root for Tom Ripley. Not to like him. Not, on some level, to want him to win. Patricia Highsmith does a fine job of ensuring he wheedles his way into our sympathies." Film critic Roger Ebert made a similar appraisal of the character in his review of Purple Noon, Rene Clement's 1960 film adaptation of The Talented Mr. Ripley: "Ripley is a criminal of intelligence and cunning who gets away with murder. He's charming and literate, and a monster. It's insidious, the way Highsmith seduces us into identifying with him and sharing his selfishness; Ripley believes that getting his own way is worth whatever price anyone else might have to pay. We all have a little of that in us." Novelist Sarah Waters esteemed The Talented Mr. Ripley as the "one book I wish I'd written." The first three books of the "Ripley" series have been adapted into films five times. In 2015, The Hollywood Reporter announced that a group of production companies were planning a television series based on the novels. The series is currently in development.
