This whole thing worked for us. It gave us a window we otherwise would never have had.

The new location was a small jail near a residential district; no one would think to look there. Except we were already looking there. Our computer, MindReader, was plugged into the Iranian military police network, courtesy of Abdul Jamar, an Iranian on the CIA payroll. Abdul’s older brother had been murdered by the secret police for writing essays in protest of the nuclear program. This was his form of payback.

When Mr. Church formed the Department of Military Sciences he built it around the MindReader computer system, which was his sole property. Bug, our head of computer operations, hinted that Church may have written some of its more advanced software packages, but Church refused to confirm it. Actually, Church simply ignored the question, which was his style. MindReader has a lot of functions, but two stand out and make it the most valuable tool in the intelligence arsenal. It is designed to look for patterns, and though computers can’t generalize, MindReader comes damn close. It gathers information from other sources, including many that refuse to share their intel with the DMS. That doesn’t matter to MindReader, and that’s the other reason it’s so valuable. It is designed to intrude into virtually any other computer system without tripping alarms, and when it backs out, it rewrites the target computer’s software so that there is no record that it had ever been hacked. The system is proprietary and no one outside of a select few DMS senior staff has access to it; and no one has full access except Church.

My team and I were staying in a seedy hotel near the center of town—one that allowed dogs—and my dog was currently waiting there for us. When we got word about the transfer, we began tracking the move through a series of high-security-coded e-mails. I had half of Echo Team with me for this: my number two, First Sergeant Bradley “Top” Sims; the big California kid, Harvey “Bunny” Rabbit; the professorial Khalid Shaheed; the laconic former LAPD sniper John Smith; and the newbie, Lydia Ruiz, who was in the navy’s first covert group of women SEALs.

Khalid was, among other things, a makeup artist who could have gotten work on Broadway. When we arrived at the hotel room, among the equipment delivered for us was a professional stage makeup kit. Khalid used it to transform us all into Iranians. Luckily a lot of people in Iran look like their European forebears. Khalid had to tone down his own darker Egyptian complexion. Bunny and I both got our fair hair dyed black. Lydia was Latina but had the olive skin of her Madrid ancestors; with the right eye makeup and a modest chador with a headscarf, she would blend right in. John Smith was already dark-haired, so Khalid gave his pale face a little more color.
