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 he was preparing to write. Could the break-in at the mental institution have been carried out by Russian agents? Did satellite surveillance show any kind of activity near the sixty-fourth parallel that might correspond with the arrival or departure of the ten kidnapped kids? Was anything known about the whereabouts of Achilles that would contradict the idea of his being in control of the whole kidnap operation?
It took a couple of days to get the story right. He tried it first as a column by Demosthenes, but he soon realized that since Demosthenes was constantly putting out warnings about Russian plots, he might not be taken very seriously. It had to be Locke who published this. And that would be dangerous, because up to now Locke had been scrupulous about not seeming to take sides against Russia. That would now make it more likely that his exposure of Achilles would be taken seriously-but it ran a grave risk of costing Locke some of his best contacts in Russia. No matter how much a Russian might despise what his government was doing, the devotion to Mother Russia
