The Mentalist is an American crime procedural television series that ran from September 23, 2008, until February 18, 2015, on CBS.
The series follows Simon Baker as Patrick Jane, an independent consultant for the California Bureau of Investigation (CBI) based in Sacramento, California and later on for the FBI.
He has a remarkable track record for solving serious crimes by using his amazing skills of observation.
He abandoned his pretense out of remorse when his attention-seeking behavior attracted the attention of a serial killer, Red John, who killed his wife and daughter.
These "red" references served as a reminder of Red John, the mysterious figure responsible for the murder of Patrick Jane's wife and daughter.
