This is my first serious Alex Rider fanfiction. These characters are property of Anthony Horowitz, I'm just borrowing them for my own enjoyment. Anyway, I hope you like it so far. Sorry the chapter's so short :/

Chapter 1

On a train a few miles outside the heart of London, sat an eighteen year old, average teenage boy with, shaggy fair hair, tanned skin from time spent abroad, and brown eyes that had already seen too much. He was athletic, although you couldn't tell from the jumper he was wearing that was one size too big for him, it did however, keep him warm. He also wore blue jeans and a white shirt underneath his jumper. He was alone in his cabin, and he was bored. He had already read all the pamphlets that were on the table and had taken a few shots of the scenery outside the window. He had also read a few chapters of the book he was assigned for school a few years ago, "The Adventures of Sherlock Holmes" by Sir Arthur Conan Doyle. It was a good book, interesting and he noticed pieces that had been taken out and modernised into the BBC rendition of Sherlock. When he pointed it out in class, the teacher had thought it was genius! But although the book was interesting, he didn't want to spend the whole trip reading. He took out his old Nintendo DS, it was blue and it was ordinary. He'd had two other DS consoles before, both hadn't been ordinary. They had been gadgets, one given to him by MI6 and the other by a couple of CIA agents. The console brought back memories, some of which he hadn't quite gotten over, but he continued to play the game anyway. It was only Mariokart, what harm could that do?

He played for another fifteen minutes, until a voice over the train's PA system told him that they were only ten minutes away from their destination. He put away the console and stared out the window, watching as buildings and traffic flew past him until the train came to a standstill.

The London tube station was as busy as he remembered. The platforms were crowded with people from tourists to businessmen. He watched them all go past as he made his way off the train. He'd only brought his backpack with him. Although that was packed with his laptop, a few sets of clothes, a bottle of water and a packet of crisps. He looked like a university student, despite his age. He'd grown taller, had a haircut and his muscles had filled him out a bit. He looked twenty. As he made his way through the crowd and into the London air, he noticed a man looking at him. He couldn't be more than thirty and somehow, he looked familiar. The stranger moved his mouth as he turned away.

Rider.

Alex Rider.

He didn't notice when another man bumped into him, sliding something into his front pocket until after he'd immersed himself in the crowd along with the other man. Alex shook them out of his head. He was in London for the first time in two years, going under a different name. He hadn't told anyone he was coming back, after all, who was there to tell?

As he came out into the bleak open air, white clouds hovering in the sky, he decided he'd walk around. Take in the sights, familiarise himself with the place again before heading off to a backpackers motel where he'd stay the night. The next day he was going to change his identity for the final time. Tomorrow Alex Rider would be dead and James Alex Williams would take his place.

But Yassen Gregorovich had other plans.
