AN: So, this is the first story I actually had the guts to publish.. Reviews are very much appreciated :)

Ofcourse, Aziraphale wasn't his real name. But that didn't matter much. Every little piece of holiness helps with a job like his. Well, with one of his jobs, at least. The bookstore was partly for cover, partly because hunting vampires didn't exactly pay well. And while it was some sort of a family affair, as a general rule, everybody took care of their own financial business.. Somehow, because he was the only one with an actual place to stay, while the other trekked around. And that place was London. It was where he lived, and it was where he hunted. And at this current moment, he was sitting on a bench in St. James' Park, waiting for his target to arrive.

He shivered. It was cold, and even with the long camel coat he was wearing, he still felt chilled to the bone. He was armed with various knives and stakes, and next to him lay a Super Soaker filled with holy water. He had to admit that, yes, it did look rather silly, but it was as effective as anything. He was just about to stand up to loosen his limbs a little, when suddenly, from the corner of his eye, he saw something moving in the shadows between the trees. He reached for his water gun. "Show yourself!"
He braced himself when he heard someone snicker. "Really? A water pistol? It's filled with holy water, isn't it? You really need something better when taking on me. Because you were planning on that, weren't you? Because I can think of very few other reasons why somebody would sit on that bench with a water pistol filled with holy water in the middle of the night." To answer that, Aziraphale fired into the trees. Blindly, because he still couldn't see who exactly was talking to him.
He knew he had failed when he heard that voice again. "Next time, aim a little higher." He was in the trees? Da- Shit. "Why don't you come out and play?" Another snicker. "This kid has spunk." He heard the sound of something hitting the ground. "You've got balls, kid, I gotta give you that." A figure came walking out of the trees. Said figure had dark hair and was wearing a suit, and, for a reason Aziraphale completely understood, a pair of dark sunglasses. He seemed to inspect Aziraphale from behind them. "Not at all what I was expecting." And then he walked away, with Aziraphale being too dumbstruck to do anything. But after a while, he managed to compose himself again, gathered his stuff, and went home.
