When the FBI steps in (and often steps on the local cops' toes), you know the situation has gotten serious. This is a round-up of all the TV series we could find featuring FBI agents from the serious to the surreal (we're looking at you Twin Peaks).
It all started with Sherlock Holmes and Dr Moriarty--the epic and prolonged chess match between two worthy adversaries--full of relentless pursuit, near captures, and tight escapes. Whether it's spies, serial killers, or terrorists these baddies are too slippery to catch easily.
Not saying these lighthearted series are formulaic, but you can create your own by pairing an eccentric psychic, novelist, conman, anthropologist, magician, etc. with a grizzled cop, private investigator, FBI agent.
An aged, retired Sherlock Holmes deals with early dementia as he tries to remember both his final case and a mysterious woman whose memory haunts him. He also befriends a fan, the young son of his housekeeper, who wants him to work again.
