Shadow of the Hegemon, the - Book 2 (Ender)

Wiggin in the final battle. I am very interested in locating her, and believe she may have been transported against her will to a place within the borders of India. If you know anything about her whereabouts and present condition, could you let someone know? I'm sure you'd want someone to do the same for you.
    Almost immediately there came an email from Achilles.
    I'm sure you understand that because this is wartime, any attempt to convey information to someone outside the Indian military will be regarded as espionage and treason, and you will be killed forthwith.
    So Achilles was definitely keeping Petra incommunicado, and cared very much that she remain hidden to outsiders.
    Virlomi did not even have to think about what she would do. This had nothing to do with Indian military security. So, while she took his death threat seriously, she did not believe there was anything morally wrong with attempting to circumvent it.
    She could not write directly to Colonel Graff. Nor could she send any kind of message containing any reference, however oblique, to Petra. Any email going out from Hyderabad was going to be scrutinized. And, now that Virlomi thought about it, she and the other Battle School graduates ensconced here in the Planning and Doctrine Division were only slightly more free than Petra. She could not leave the grounds. She could not have contact with anyone who was not military with a high-level security clearance.
    Spies have radio equipment or dead drops, thought Virlomi. But how do you go about becoming a spy when you have no way to reach outside but writing letters, yet there's no one you can write a letter to and no way to say what you need to say without getting caught?
    She might have thought of a solution on her own. But Petra simplified the process for her by coming up behind her at the drinking fountain. As Virlomi straightened up from drinking and Petra slipped in to take her place, Petra said, "I am Briseis."
    And that was all.
    The reference was obvious--everyone in Battle School knew the Iliad. And with Achilles being their overseer at the moment, the Briseis references was obvious. And yet it was not. Briseis had been held by someone else, and Achilles-the original one-had been furious because he felt slighted that he didn't have her. So what could she mean by saying she was Briseis?
    It had to do with the letter from Graff and Achilles' warning. So it must be a key, a way to get word out about Petra. And to get word out required the net. So Briseis must mean something to someone out on the net. Perhaps there was some kind of coded electronic dead drop, keyed on the name Briseis. Perhaps Petra had already found someone to contact, but could not do it because she was cut off from the nets.
    Virlomi didn't bother doing a general search. If someone out there was looking for Petra, the message would have to be at a site that Petra would be able to find without deviating from legitimate military research. Which meant that Virlomi probably already knew the site where the message was waiting.
    The problem she was officially working on at the moment was to determine the most efficient way to minimize risk to supply helicopters while not consuming too much fuel. The problem was so technical that there was no way she could explain doing historical or theoretical research.
    But Sayagi, a Battle School graduate five years her senior, was working on problems of pacifying and winning the allegiance of local populations in occupied countries. So Virlomi went to him. "I've gone greeyaz on my algorithms."
    "You want my help?" he asked.
    "No, no, I just need to set it aside for a couple of hours so I can come back to it fresh. Anything I can help you look for?"
    Of course Sayagi had received the same messages as Virlomi, and he was sharp enough not to take Virlomi's offer at face value.
    "I don't know, what kind of thing could you do?"
    "Any historical research? Or theoretical? On the nets?" She was tipping him to what she needed. And he understood.
    "Toguro. I hate that stuff. I need data on failed approaches to pacification and conciliation. Besides killing or deporting everybody and moving in a new population."
    "What do you already have?"
    "You're wide open, I've been avoiding it."
    "Thanks. You want a report or just links?"
    "Paste-ups are enough. No links, though. That's too much like doing the work myself."
    A perfectly innocent exchange. Virlomi had her cover now.
    She went back to her desk and began
