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.
With these neo-noir series you can expect conflicted, world-weary antiheroes, grisly crimes, corrupt cops and politicians, and some dark humor to boot; just make sure you turn the brightness all the way up on your TV.
