Developing a concept.

I've been throwing the idea around of a secret organization called the Bookers. These people have been around for decades, their main job is to investigate and compromise supernatural and strange activity around the world.
The timeline consists of the present, however the organization is still very old fashioned, including old suits and uniforms as well as old weapons.They aren't a very big organization however they keep it that way so that only they know about it.
My inspiration for this concept came from the movie Looper, where people called "Loopers" in the future would kill people that were sent into the future from the past.
