Killer Genius — David Archer

Sam is after a serial killer who has eluded everyone for a long time, and even the Windlass Team is coming up empty. Out of desperation, he agrees to work with a young man who is considered a genius, but one of those who is so close to the line between genius and insanity that he is carefully controlled by a contracted agency that watches over them for the government.

That leads to the discovery that not everything at the facility is as it seems, and things take a dark turn when Sam comes to realize that the young man is being abused and used. Now it's up to Sam and his team to get to the bottom of it.
