For the first fifteen minutes of the drive, Knox feared that Peterson would discover him at any moment in the back of the Toyota. But as they clocked up the miles, he simply grew bored, having to remind himself that he was just a few feet away from a man who'd almost certainly tried to kill him twice already.
As best he could judge, they were on a busy, good road. The angle of sunlight suggested they were heading south. Towards Cairo, presumably, though Knox had no idea why. After two hours or so, Peterson applied the brakes sharply enough to push Knox forward into the back of the rear seats. The indicator stuttered; they turned off, pulled to a stop. Peterson got out, unscrewed the petrol cap right by Knox's head. Fuel gushed in. Knox kept absolutely still lest movement give him away. The cap was screwed back on. Knox heard footsteps over the concourse. He allowed himself to breathe once more. He sat up in time to see Peterson go inside the office to pay. He climbed over the rear seats, intending to let himself out, but then he glimpsed some sheets of paper lying loose on the passenger seat, the top one a printout from Gaille's Internet Digging Diary, that photograph of her standing outside her room with two archaeologists from Fatima's team. He froze a moment, then slid it aside to look at the one beneath it. Another print-out, this one with directions to Fatima's Hermopolis compound. So that was it. Peterson was spooked by the thought of his photos still on Gaille's laptop.
A door banged closed. He glanced up to see Peterson coming back out. He had no time to resume his previous position. He ducked down behind the driver's seat as Peterson climbed back in.
