What is the author's style in The Talented Mr. Ripley by Patricia Highsmith?

The novel is told in the third person past tense from Tom Ripley's point of view. The focus on Tom is extremely close, showing his thoughts and calculations and even, at times, his unconscious motivations. Almost every time Tom tells a lie, the reader is aware of it through Tom's thoughts. This technique is extremely effective at exposing the reader to Tom's deceptions, and his cold calculations to avoid punishment, even after committing two murders.
