4. Patrick Jane - The MentalistPlayed by Simon Baker, Patrick Jane is technically not a detective but rather a consultant for the California Bureau of Investigation who started his work after his family were brutally killed by mysterious serial killer Red John. He is also not a detective in the traditional sense of the word, he is a former TV psychic using his powers of deduction to solve murders happening within California. Thankfully, he has admitted his psychic skills were a complete fraud and thus looks down on anyone else who claims to have true psychic skills. That, you might appreciate, has annoyed an awful lot of people that sought to help the CBI in its investigations but hey things get done eventually so where's the harm? While Jane does get results he does it by putting his co-workers in dangerous situations by simply not telling them what his plans are - to the deep annoyance of superior Teresa Lisbon. In the world of TV this all works, whether it would in real life is a mystery. That system also rubs up suspects the wrong way who, rather than tutting, would much rather pull out various weapons and decide to bring the pain. It's also to be seen whether he would still have the urge to carry on solving crime if Red John finally got collared. But now into its sixth season the show seems to give Jane no luck in catching the master criminal so maybe that question will never need to be answered.
