Just before dawn, the sky filling with light, indigo paling to dark blue, the faintest stars fading out, The Pack Came, their arrival heralded by the blat of a car alarm, which, she realized, Wayne must have rigged for exactly this purpose—in an instant, she had hefted the rifle to her cheek and one of the Pack leapt into focus; she moved the gun back and forth and saw two behind that one, and one more bringing up the rear, the four of them about ten feet behind the rope barrier, making their way slowly, placing each plate-sized foot with care, stopping to sniff the road in front of them, pausing to study the Bridge’s support cables-there was enough time for Jackie to verify her initial count a second, a third time, and once she was certain that the four things she saw were the Pack, that was it, there were no others padding along behind them, her heart lifted with a fierce joy and she thought, Four, there are four of them; we can do this; Wayne was right; we can be free of them, finally—they were in rough shape, these four; it looked as if they’d pulled themselves from the wreckage of the trap at the mall: their hides were decorated with cuts, slashes, burns; patches of hair had been torn and scraped away; flaps of skin hung down like streamers; the one she’d focused on first appeared to have something wrong with its left eye, which was crusted with dark blood, while the one bringing up the rear was trailing its left back leg behind it-that they had survived made them the fittest, yes, thank you, Mr. Darwin, but watching their cautious advance, Jackie was reminded of her grandmother’s dog, a poodle that had been old when she was a child and had grown steadily more gray, more infirm, more trembling and tentative each year, and if her heart wasn’t moved to pity; the last four weeks had insured the impossibility of that; the association tempered her joy-It’s time to end this, she thought, and turned to wake Wayne, who was (of course) already up and jamming pistols into his jeans, slipping the strap of his bag-of-tricks over his head, his face still-he crouched beside her, holding a third pistol out to her: "In case one of them makes it past me," he said as she took it, checked the safety, and set it on the rock beside her—he reached for her backpack, dragged it around for her to lean on: "Take the one to the rear," he said, "and any others that try to escape," and before she could answer, he was running away from her, heading back along the ledge-holding the rifle aloft with her right hand, Jackie eased herself up and down, until she was lying against the backpack, then brought the rifle into position, fitting the stock against her shoulder, anchoring it against the meat to take the kick, which Wayne had assured her wasn’t that bad—she looked through the sight and there were the Pack, stopped in their tracks, their hackles raised; she could hear them, a deep bass note like a viol whose strings were frayed out of true, and she curled her finger around the trigger, ready for them to panic and flee, reminding herself to squeeze, not pull, and wondering if she would be able to hit, let alone stop, any of them-Wayne was running down the road toward the Bridge, his hands empty, and when the Pack saw him, the note they were holding rose to a ragged shriek, drowning out whatever Wayne was shouting at them; taunting them, no doubt, urging them on (and a part of her wondered why that should work, why animals would respond to insult, and she wondered if they weren’t animals, but wasn’t sure what such a question implied, because she couldn’t imagine machines being bothered by Wayne’s provocations, which left what? people? which was ridiculous).
