text was Roman and Arabic, that was a poor analysis because I used multiple symbolic systems. The same is true for Roman and runic.»
Sato crossed her arms and arched her eyebrows as if to say, «Go on.»
«In general, communications are made in
«And you see a single system now?»
«Well, yes. . and no.» Langdon’s experience with the rotational symmetry of ambigrams had taught him that symbols sometimes had meanings from multiple angles. In this case, he realized there was indeed a way to view all seven symbols in a single language. «If we manipulated the hand slightly, the language will become consistent.» Eerily, the manipulation Langdon was about to perform was one that seemed to have been suggested by Peter’s captor already when he spoke the ancient Hermetic adage.
Langdon felt a chill as he reached out and grasped the wooden base on which Peter’s hand was secured. Gently, he turned the base upside down so that Peter’s extended fingers were now pointing straight down. The symbols on the palm instantly transformed themselves.

«From this angle,» Langdon said, «X–I-I–I becomes a
«sbb?» the chief demanded.
Sato turned to Anderson. «If I’m not mistaken, that sounds like a familiar numbering system here in the Capitol Building.»
Anderson looked pale. «It is.»
Sato gave a grim smile and nodded to Anderson. «Chief, follow me, please. I’d like a word in private.»
As Director Sato led Chief Anderson out of earshot, Langdon stood alone in bewilderment.
Chief Anderson wondered how this night could possibly get any stranger.
Director Sato led Anderson over to a quiet area near the bronze statue of Thomas Jefferson. «Chief,» she said, «I trust you know exactly where SBB Thirteen is located?»
«Of course.»
«Do you know what’s inside?»
«No, not without looking. I don’t think it’s been used in decades.»
«Well, you’re going to open it up.»
Anderson did not appreciate being told what he would do in his own building. «Ma’am, that may be problematic. I’ll have to check the assignment roster first. As you know, most of the lower levels are private offices or storage, and security protocol regarding private — »
«You will unlock SBB Thirteen for me,» Sato said, «or I will call OS and send in a team with a battering ram.»
Anderson stared at her a long moment and then pulled out his radio, raising it to his lips. «This is Anderson. I need someone to unlock the SBB. Have someone meet me there in five minutes.»
The voice that replied sounded confused. «Chief, confirming you said SBB?»
«Correct. SBB. Send someone immediately. And I’ll need a flashlight.» He stowed his radio. Anderson’s heart was pounding as Sato stepped closer, lowering her voice even further.
«Chief, time is short,» she whispered, «and I want you to get us down to SBB Thirteen as quickly as possible.»
«Yes, ma’am.»
«I also need something else from you.»
Sato motioned across the room toward the professor. «The duffel bag on Langdon’s shoulder.»
Anderson glanced over. «What about it?»
«I assume your staff X-rayed that bag when Langdon entered the building?»
«Of course. All bags are scanned.»
«I want to see that X-ray. I want to know what’s in his bag.»
Anderson looked over at the bag Langdon had been carrying all evening. «But. . wouldn’t it be easier just to ask him?»
«What part of my request was unclear?»
Anderson pulled out his radio again and called in her request. Sato gave Anderson her BlackBerry address and requested that his team e-mail her a digital copy of the X-ray as soon as they had located it. Reluctantly Anderson complied.
Forensics was now collecting the severed hand for the Capitol Police, but Sato ordered them to deliver it directly to her team at Langley. Anderson was too tired to protest. He had just been run over by a tiny Japanese steamroller.
«And I want that ring,» Sato called over to Forensics.
The chief technician seemed ready to question her but thought better of it. He removed the gold ring from Peter’s hand, placed it in a clear specimen bag, and gave it to Sato. She slipped it into her jacket pocket, and then turned to Langdon.
«We’re leaving, Professor. Bring your things.»
«Where are we going?» Langdon replied.
«Just follow Mr. Anderson.»
CHAPTER 27
Systems security specialist mark zoubianis had always prided himself on his ability to multitask. at the moment, he was seated on his futon along with a tv remote, a cordless phone, a laptop, a pda, and a large bowl of pirate’s booty. with one eye on the muted redskins game and one eye on his laptop, zoubianis was speaking on his bluetooth headset with a woman he had not heard from in over a year.
Confirming her social ineptitude yet again, his former colleague had chosen the Redskins game as a perfect moment to chat him up and request a favor. After some brief small talk about the old days and how she missed his great jokes, Trish had gotten to her point: she was trying to unmask a hidden IP address, probably that of a secure server in the D.C. area. The server contained a small text document, and she wanted access to it. . or at the very least, some information about whose document it was.
