Four

I am a killer. Not those cheesy ones, like 007, but an actual killer. I know what your thinking, what with the me being thirteen and all that, but I am. I infiltrate places, gather information, and never use my real name. That's because I have no real name. Like all the other members of the Achilles program, I have a number. My number is Four. That number is unlucky in some places, but it's true. I am the fourth student to be chosen for the Achilles program, out of the 600 and growing. And I am the best. There is no hiding from me. If I need to find and kill you, I will do it. All you can do is hope for a swift death.
