Theo, she thought, as the pain in her leg abruptly deepened-a wave of heat and light that bent her double. The leg folded beneath her, sending her pitching forward. Theo, I’m here. I’ve come to save you. We have a baby, Theo. Our baby is a boy.

As she fell she saw a figure sprinting across the ring. It was Amy. Her hair was pulling a trail of smoke; darting tongues of fire were licking at her clothing. The viral had shifted his attention toward Theo now. Amy charged between them, protecting Theo like a shield. Faced with the creature’s immense, bloated form, she seemed tiny, like a child.

And in that instant, which felt suspended-the whole world brought to a halt while the viral regarded the small figure before him-Mausami thought: that girl wants to say something. That girl is going to open her mouth and speak.

Twenty meters overhead, Hollis had dropped through the vent with his rifle, followed by Alicia, holding the RPG. She swung it toward the floor, pointing its barrel at the place where Amy and Babcock stood.

“I don’t have a shot!”

Caleb and Sara dropped through behind them. Peter snatched Jude’s shotgun from the floor of the catwalk and fired in the direction of the two men racing down the catwalk toward them. One man uttered a strangled cry and fell away, tumbling headfirst to the floor below.

“Shoot the viral!” he called to Alicia.

Hollis fired and the second man dropped, face-down, onto the catwalk.

“She’s too close!” Alicia said.

“Amy,” Peter yelled, “get out of there!”

The girl stood her ground. How long could she hold him that way? And where was Olson? The last of the fires had gone out; people were streaming down the stairs, an avalanche of orange jumpsuits. Theo, on his hands and knees, was backing away from the viral, but his heart was nowhere in this; he had accepted his fate, he had no strength to resist. Caleb and Sara had made it across the catwalk to the stairs now, descending into the melee on the balconies. Peter heard women screaming, children crying, a voice that sounded like Olson’s, rising over the din: “The tunnel! Everyone run to the tunnel!”

Mausami lurched into the ring.

“Over here!” She stumbled, catching herself with her hands as she fell to the floor. Her pants were soaked in blood. On all fours, she tried to rise. She was waving, screaming: “Look over here!”

Maus, Peter thought, keep back.

Too late. The spell was broken.

The viral rocked its face toward the ceiling and drew down into a crouch, its body gathering energy like a coiled spring, and then it was flying, lofting through the air. It rose toward them with a pitiless inevitability, arcing over their heads and seizing one of the ceiling struts, body rotating like child swinging on a tree limb-an oddly exhilarating, even joyful image-and landed on the catwalk with a shuddering clang.

I am Babcock.

We are Babcock.

“Lish-”

Peter felt the RPG sailing past his face, the scald of hot gas on his cheek; he knew what was going to happen before it did.

The grenade exploded. A punch of noise and heat and Peter was shoved backward into Alicia, the two of them tumbling onto the catwalk, but the catwalk wasn’t there. The catwalk was falling. Something caught and held and they banged down hard, and for a hopeful moment everything stopped. But then the structure lurched again, and with a pop of rivets and a groan of bending metal the end of the catwalk broke away from the ceiling, tilting toward the floor like the head of a hammer, falling.

Leon in the alley, face-down in the dirt. Goddamn, he thought. Where did that girl go?

Some kind of gag was in his mouth; his wrists were bound behind him. He tried to wriggle his feet, but they were tied, too. It was the big one, Hollis; Leon remembered now. Hollis had risen out of the shadows, swinging something, and the next thing Leon knew he was all alone in the dark and couldn’t move.

His nose was thick with snot and blood. Probably the son of a bitch had broken it. That was all he needed, a broken nose. He thought he’d cracked a couple of teeth, too, but with the gag in his mouth, his tongue stuffed behind it, he had no way to check.

It was so goddamn dark out here he couldn’t see two feet in front of his face. The reek of garbage was coming from somewhere. People were always putting it in the alleys instead of taking it to the dump. How many times had he heard Jude tell people, Take your fucking garbage to the dump. What are we, pigs? A joke, sort of, since they weren’t pigs but what was the difference, really? Jude was always making jokes like that, to watch people squirm. For a while they’d kept pigs-Babcock liked pork almost as much as he liked the cattle-but some kind of sickness had wiped them out one winter. Or maybe they’d just seen what was coming and decided, What the hell, I’d rather just lie down and die in the mud.

No one would be coming to look for Leon, that was for sure; the problem of standing up was his to solve on his own. He could sort of see a way to do it, by drawing his knees to his chest. It made his shoulders hurt something terrible, twisted back like they were, and pushed his face, with its broken nose and teeth, into the dirt; he gave a yelp of pain through the gag, and by the time he was done with it, he was woozy and breathing hard, the sweat popping out all over. He lifted his face-more pain in his shoulders, what the fuck had that guy done, tying his hands so tight-and raised his upper body until he was sitting up, his knees folded under him, and that was when he realized his mistake. He had no way to stand. He’d sort of thought he could push off with his toes, jumping his way into a standing position. But this would just send him pitching forward onto his face again. He should have scooched over to the wall first, used it to shimmy his way up. But now he was stuck, his legs jammed up under him, frozen in place like a big dumbshit.

He tried to cry for help, nothing fancy, just the word “Hey,” but it came out as a strangled Aaaaa sound and made him want to cough. Already he could feel the circulation going out of his legs, a prickly numbness crawling up from his toes, like ants.

Something was moving out there.

He was facing the mouth of the alley. Beyond it lay the square, a zone of blackness since the fire barrel had gone out. He peered into the dark. Maybe it was Hap, come to look for him. Well, whoever it was, he couldn’t see a goddamn thing. Probably his mind was playing tricks on him. Alone outside on new moon, anybody could get a little jumpy.

No: something was moving. Leon felt it again. The feeling was coming from the ground, through his knees.

A shadow streaked above him. He lifted his head quickly, finding only stars, set in a liquidy blackness. The feeling through his knees was stronger now, a rhythmic shuddering, like the flapping of a thousand wings. What the goddamn-?

A figure darted into the alley. Hap.

Aaaaaaaaa, he said through the gag. Aaaaaaaaa. But Hap seemed not to notice him. He paused at the edge of the alley, panting for breath, and raced away.

Then he saw what Hap was running from.

Leon’s bladder released, and then his bowels. But his mind was unable to register these facts as all thought was obliterated by an immense and weightless terror.

The end of the catwalk impacted the floor with a massive jolt. Peter, clutching one of the guardrails, barely managed to hold on. An object tumbled past him, clattering end over end before bounding into space: the empty RPG, spiraling a meteoric wick of smoke from its tube. Then something heavy struck him from above, ripping his hand away-Hollis and Alicia, tangled together-and that was that: the three of them were falling free, sliding down the angled catwalk to the floor below.
