Without Time

I'm unique, I sneak into other people's computers (like hacking but without the mess), I pick pocket people to learn more about them but I never steal the item, it is always returned before the owner realizes that it's gone, I love leaving notes for people when I borrow something from them. I occasionally break into homes to return an item but I will leave the item along with a gift for them and multiple notes. Crazy is the main thing that people call me, thinking that I'm just giving myself away but I love leaving notes, and half the time no one even cares as long as nothing is taken. Living in Britain was no exception, I planned on being in and out BEFORE becoming a national threat and shipped out. (I'll explain later), but something went wrong, my genius mind decided that it would become infatuated with a man who drug me into a hole and decided that my crazy mind would come in handy to catch criminals.
