The water was warm by the standards of oceans, but her immediate and powerful impression was of being cold. Then she got over it and started swimming.
They seemed to be in the lee of Kinmen. The waves were not as powerful, but they came from many directions and clashed into sudden pyramids of water that just as suddenly collapsed. She just tried to get a bearing on the moon and to keep swimming at all costs. The main thing that she was worried about was being swept out to sea by some unseen current, and indeed when she pulled her head up out of the soup to look at the lights of the island, she got the impression that they were moving sideways at least as fast as forward. She was not much of a nautical person but was enough of a Brit to have absorbed, by osmosis, certain terminology such as “slack water,” and she was pretty sure that this was the condition that obtained now: the tide was low, neither incoming nor outgoing, and the water wasn’t moving much. But huge rivers emptied into the sea around Xiamen and their flow had to divert around these islands, and there must be currents associated with that.
After passing through a few emotional swings, she came to the realization that they simply hadn’t been in the water for that long, she hadn’t given this nearly enough time, and just had to keep swimming. She and Sokolov both resorted to the sidestroke and the backstroke when they got fatigued. In the latter position, she watched a helicopter make several passes over the waters nearer to Kinmen than to Xiang’an, probing the seas with a spotlight, and reckoned that the boat must have been noticed on radar. It was natural to feel vulnerable and obvious and exposed. But she tried to imagine what it must be like to be sitting in the cockpit of that chopper with many square miles of dark water beneath and only a needle-thin spotlight beam. If she were a shipwrecked mariner, desperately hoping to be seen and rescued, she would despair of ever being found; so why should she concern herself about it?
Sokolov doffed his life vest and disappeared beneath the water for perhaps half a minute, then resurfaced gasping for breath. “Maybe three meters,” he said, apparently giving an estimate of the water’s depth. She liked the sound of that.
It was perhaps half an hour later that something grazed her fingertip during a deep stroke, and she realized that she could stand up. Probably could have stood up a while ago.
A moment later she was looking down into the astonished face of Sokolov, who was doing the backstroke. He got his legs under him, then gestured with one hand in a way that clearly meant Get down, idiot!
They squatted with only their heads above the water and surveyed the shore ahead of them as best they could in the faint light of the moon. Olivia had the impression of gazing through the broken teeth of a ruined comb.
“Tank traps,” Sokolov said. “To stop amphibious landing. No problem for us. As long as we stay out of tank.”
Humor. She was too shattered to appreciate it. When she had made it back to her apartment after the gun battle and explosion, an improvised bandage on her head, she’d planned to crawl into bed and not come out for a long time. With some effort, and with Sokolov’s help, she had goaded herself into making a trip out to the wangba to send out a distress call. Adrenaline had propelled her through the last hour’s events. But as soon as she felt land under her feet and exited swim-or-die mode, the bottom fell out. She dropped to all fours in the shallow surf, not just as a way of keeping her head down but because she did not think herself capable of standing up. Like a prehistoric fish dragging itself up onto the strand by its floppy, vestigial fins, she followed Sokolov up into shallower and shallower water and finally onto a sandy beach guarded by a vast defensive works: a double picket line of spikes angled toward the mainland. As became clear when they got closer, each spike was a railroad rail that had been planted in a massive tub of concrete and cut off at an angle to make it sharp. A fat eye bolt projected from the top of each cement block, which was apparently how they’d been lifted from a barge and dropped into place, one by one, during some long-forgotten Cold War defensive buildup. Rust had thinned the steel, barnacles thickened and furred it. The blocks had settled into diverse angles. Sokolov was right that this was no impediment to them.
A couple of meters beyond the tank traps they encountered a region of hexagonal blocks that had been sunk into the sand, apparently to stop beach erosion; these formed a strip of wildly uneven pavement maybe ten meters wide, running as far as they could see (which was not very far) in either direction.
Beyond that it was just a beach like any other. Alive, though, under her hands. For thousands of tiny crabs, no larger than beetles, were scuttling about, going in and out of pencil-sized holes in the sand.
Sokolov hissed at her, and she realized she’d gone too far. She flattened herself against the sand, glad of an opportunity to lie down and stop moving, even if she were wet and cold. He was a few meters behind her, draped over the dark hexagonal blocks, invisible even to Olivia who knew where he was.
They lay there for a few minutes, waiting and watching. Olivia had begun to shiver upon coming out of the water and was now doing so convulsively. Her teeth literally chattered together for the first time since she’d been four years old. She opened her mouth wider to stop the noise.
