Alex Rider had made his own choices. He should have been at school, but instead, for whatever reason, he had allowed the Special Operations Division of MI6 to recruit him. From schoolboy to spy. It was certainly unusual – but the truth was, he had been remarkably successful. Beginner’s luck, maybe, but he had brought an end to an operation that had been several years in the planning. He .
