I Spy a 2P

In a seemingly normal world, a group of specialised professionals are trained and sent on missions to sort out the worst kind of people... Well, worse than them, of course.
With orphans who show potential being taken from childhood, and adults who are suitable being bribed, the Institution has become one of the strongest secret services in the world. Oliver Kirkland - renowned mass murderer, ex-marine and baking fanatic - gets forced into one of the training programmes, and meets some interesting people along the way.
