I was a real-life secret agent. I didn't have the hand-grenade cuff links or the poison-dart pen, but in 2004 I was recruited by the Department of Homeland Security for its Red Cell program.

As they described it - and as The Washington Post later reported - Red Cell was the government's way of trying to anticipate how terrorists would next attack the United States. To do that, the government brought together what they called "out-of-the-box thinkers."
