It hadn’t occurred to her before, but: she had to cross the Chinese border somehow . Crossing at any legal port of entry would leave traces impossible to reconcile with her cover story. Even if she did it with fake papers and then threw them away, they’d have photos of her, and you had to assume they were using digital face recognition software now. Theoretically she could have hiked across the border from some place like Laos or Tibet, but that seemed awfully Victorian. They simply didn’t have time. So it was going to be this. At three in the morning she put on the scuba gear and carried her waterproof pouch to the miniature pod-sub, where, as promised, five of the SBS men were waiting. Some kind of long and tedious procedure followed, involving lots of checklists. The thing filled with water and started to move independently of the big submarine.
