The Mentalist is an American crime drama television series created by Bruno Heller, which aired from 2008 to 2015 across seven seasons. The story centers on Patrick Jane, a former psychic medium turned detective consultant with an uncanny ability to observe and deduce information that others miss. Jane works for the California Bureau of Investigation (CBI) alongside Agent Teresa Lisbon and her team. A unique twist in Jane’s background sets this series apart: he joined CBI to hunt down a brutal serial killer known as Red John, who murdered Jane’s wife and daughter after Jane publicly mocked him. His main goal in joining law enforcement is not justice in the traditional sense but rather personal revenge. This central theme of seeking retribution intertwines with the weekly mystery cases that Jane helps solve, making the show a blend of psychological drama, suspense, and crime-solving.

The season ends with tantalizing clues suggesting that Red John may be closer than expected.
