I would be interested. How about the FBI take a trainee or younger agent, and after months of murders and not being able to catch the guy, they "set up" the younger agent as bait to try and lure the murderer? This could go wrong, or not, depending on how it turns out. Obviously the story would have to lead up to this.

I'll gladly be the younger agent, or a victim the FBI works with. I would really love to do this story, but I'm really worried over the murderer becoming some kind of godmodding hero that is super human in terms of intelligence and getting away...
Mostly I just want this to stay realistic, and if that can happen, I'm 100% in. :)
