he CIA agent tapped softly on the hotel room door. After the keynote speeches, panel discussions and dinner, the conference attendees had retired for the night. Audio and visual surveillance of the room showed that the nuclear scientist's minders from the Islamic Revolutionary Guard Corps were sleeping, but he was still awake.

According to a person familiar with this encounter, which took place about a decade ago, the agency had been preparing it for months. Through a business front, it had funded and staged the conference at an unsuspecting foreign centre of scientific research, invited speakers and guests, and planted operatives among the kitchen workers and other staff, just so it could entice the nuclear expert out of Iran, separate him for a few minutes from his guards, and pitch him one-to-one. A last-minute snag had almost derailed the plans: the target switched hotels because the conference's preferred hotel cost $75 more than his superiors in Iran were willing to spend.
