He is behind the kidnapping. When it is revealed that this psychopath has control of these children, it will cause grave misgivings inside the Russian command system. It will also give them a scapegoat if they decide to return the children.
Don't bother trying to trace this email identity. It already never existed. If you can't figure out who I am and how to contact me from the research you're about to do, then we don't have much to talk about anyway.
Peter's heart sank when he opened the letter to Demosthenes and saw that it had also been sent to Locke. The salutation "Dear Peter Wiggin" only confirmed it-someone besides the office of the Polemarch had broken his identities. He expected the worst-some kind of blackmail or a demand that he support this or that cause.
To his surprise, the message was nothing of the kind. It came from someone who claimed to have received a message from the kidnapped kids-and gave him a tantalizing path to follow. Of course he immediately searched the news archives and found the break-in at a high-security mental hospital near Genk. Finding the name of the inmate who got away was much harder, requiring that, as Demosthenes, he ask for help from a law enforcement contact in Germany, and then, as Locke, for additional help from a friend in the Anti-Sabotage Committee in the Office of the Hegemon.
It yielded a name that made Peter laugh, since it was in the subject line of the email that prompted this search. Achilles, pronounced "ahSHEEL" in the French manner. An orphan rescued from the streets of Rotterdam by, of all things, a Catholic nun working for the procurement section of the Battle School. He was given surgery to correct a crippled leg, then taken up to Battle School, where he lasted only a few days before being exposed as a serial killer by some of the other students, though in fact he had not killed anyone in the Battle School.
The list of his victims was interesting. He had a pattern of killing anyone who had ever made him feel or seem helpless or vulnerable. Including the doctor who had repaired his leg. Apparently he wasn't much for gratitude.
Putting together the information, Peter could see that his unknown correspondent was right. If in fact this sicko was running the operation that was using these kids for military planning, it was almost certain that the Russian officers working with him did not know his criminal record. Whatever agency liberated Achilles from the mental hospital would not have shared that information with the military who were expected to work with him. There would be outrage that would be heard at the highest levels of the Russian government.
And even if the government did not act to get rid of Achilles and release the kids, the Russian Army jealously guarded its independence from the rest of the government, especially the intelligence-and-dirty-jobs agencies. There was a good chance that some of these children might "escape" before the government acted-indeed, such unauthorized actions might force the government to make it official and pretend that the "early releases" had been authorized.
It was always possible, of course, that Achilles would kill one or more of the kids as soon as he was exposed. At least Peter would not have to face those particular children in battle. And now that he knew something about Achilles, Peter was in a much better position to face him in a head-to-head struggle. Achilles killed with his own hands. Since that was a very stupid thing to do, and Achilles did not test stupid, it had to be an irresistible compulsion. People with irresistible compulsions could be terrifying enemies-but they could also be beaten.
For the first time in weeks, Peter felt a glimmer of hope. This was how his work as Locke and Demosthenes paid off-people with certain kinds of secret information that they wanted to make public found ways to hand it to Peter without his even having to ask for it. Much of his power came from this disorganized network of informants. It never bothered his pride that he was being "used" by this anonymous correspondent. As far as Peter was concerned, they were using each other. And besides, Peter had earned the right to get such helpful gifts.
Still, Peter always looked gift horses in the mouth. As either Locke or Demosthenes, he emailed friends and contacts in various government agencies, trying to get confirmation of various aspects of the story
