Then the giant vehicle lumbered on, putting on a surprising spurt of speed as it skirted the square and disappeared after the 4×4s.
For a couple of minutes after the lights disappeared and the vehicles were out of sight, everyone remained where they were. Lucy-Anne listened to the engines fading away, echoes coming back at them and playing tricks with direction and distance. Then Rosemary crawled across to them, her eyes wide, fearful, and perhaps excited as well. “Choppers!” she said. “And that big monster was one of their mobile labs. I've watched Irregulars taken into there, never to be seen again.”
“We need to go to your house,” Jack said. Emily was still shivering in his arms. “It's been a long day, Rosemary, and we need rest. This is all too much.”
“Near miss, eh?” Sparky said, crawling across to them.
“Got it all on here, I think,” Emily said, holding up her camera and smiling weakly.
“There won't be another patrol for a while,” Rosemary said.
“I need to find my family,” Lucy-Anne whispered. Her heart was thrumming, and something had started ticking deep inside her, a timer slowly running out of sand. She was counting down to something, and she had no idea what.
“Not yet,” Jack said.
“Lucy-Anne, we need—” Jenna began.
“My family!” she said, louder this time. “We've come all this way, been through those bloody tunnels…those dogs! And I'm not just going to go to fucking sleep!”
“Quiet!” Rosemary said.
“Stop telling me to be quiet, old woman!”
“Lucy-Anne.” Jack stepped forward and held her arms, trying to pull her close. She resisted, pulling back, staring over Jack's shoulder at something more distant.
“Where did they live?” Rosemary said. Her voice was calmer now, cooler.
Lucy-Anne glanced at her, but said nothing.
“Answer her,” Jack said. “She knows the city.”
“She led us to those dogs.”
“Tooting, wasn't it?” Jenna asked. “Didn't they live near the big police station in Tooting?”
Rosemary sighed and lowered her head.
“What?” Lucy-Anne demanded. “What the hell does that mean?”
“Tooting isn't there anymore,” Rosemary said softly. “We just walked across it, and now it's called the Barrens.”
Lucy-Anne gasped, and her defences fell from her in a heartbeat. She crumpled in Jack's arms, slumping down as though her knees had given out. She wished he could hold her tight enough to stop everything, just for a while.
“It doesn't mean they're dead,” he whispered in her ear.
No, they're not dead, she thought. And something deep inside seemed to grin.
She pulled away from Jack and stood on her own. She smoothed down her clothes, ran her fingers through her hair, and wiped an errant tear from her cheek. Then she glanced at Rosemary. “Sorry.” The word was quiet, but they all heard it in the silence.
Rosemary nodded and gave a brief smile. “We should go. If we hurry, we can be there before it's fully dark.”
They followed the woman out of the square and along a narrow street, as they had been following her all that long day. She had led them out of the world they knew and into one they used to know, but which was now a mysterious, dangerous place. She had healed their wounds after the dogs attacked them, and told them about the strange places beneath London, both old and new. She had walked them across the largest grave the world had ever seen, and pointed out monuments to individual people that seemed, in Lucy-Anne's eyes at least, to be more immediate than the thought of a million dead.
She trusted the old woman, and she didn't. She liked her, and she feared her. And as Rosemary unlocked the front door to an innocuous, terraced house in a street that had once sung with life, Lucy-Anne wondered whether history was too powerful for any of them to change.
