“You can get from the Pons Absconditus to anywhere, can’t you?”
“Of course,” said Mortar. “So long as it’s somewhere. That’s what bridges are for— getting to somewhere. Where do you want to go?”
“Please come with me,” Brokkenbroll said. “And…” He looked thoughtful, and was silent for several seconds. “Yes. You too, young Miss Resham. I think you deserve an explanation. A little while back, I found something. Where to? Set course. We’re going to Ben Hue Unstible’s workshop.”
“What?” said Mortar.
“I’m not leaving Zanna,” Deeba said. “Look at her.”
Zanna lay on a sofa, tended by Propheseers. Her eyes were closed. She was sweating, and pale, and with every breath her lungs made an ugly sound.
“I didn’t know,” the book whispered.
“You can’t help her,” Brokkenbroll said. “Not here. Not yet. But come with me, and I’ll show you how you may be able to.”
“She won’t be safe,” Deeba said.
“She will,” said Lectern. “We can keep the bridge moving.”
“The main mass of the Smog doesn’t know what’s happened,” Brokkenbroll said. “Eventually, a few wisps of this battle may reach it, but there’s time.”
“I just want to go home,” said Deeba, “and take Zanna with me.”
“Of course,” said Brokkenbroll. “That’s what I’d like to facilitate. Believe me.”
Mortar, Lectern and the book, Deeba and Curdle, the Unbrellissimo, and his obedient unbrellas walked down the curve of the bridge.
“Even when the Smog does find out what happened,” Brokkenbroll said, “I think the course of events might put some fear into it.
“It knows that we’re approaching a big fight,” he said. “It’s been preparing for years. Now it’s started. That’s why it attacked the Shwazzy,” he said to Deeba gently. “It was scared of her. It wanted her out of the way before the war. It’s going to attack UnLondon soon.
“But now we’ve given it something to think about. I’ll explain everything.”
They were near the end of the bridge. Mortar and Lectern focused thoughtfully on the streets ahead.
“Let’s go…” Mortar said, and stepped off the end.
“Don’t worry,” Lectern said to Deeba, and tried to give her a reassuring smile. “I know you want to take care of your friend. We’ll make sure everything’s okay.” She beckoned, and followed Mortar, Deeba only a few steps behind.
She took several steps before realizing that the buildings beside her didn’t look much like they had a few seconds before. They were unfamiliar charcoal-colored edifices in the light of the early-evening loon.
There was no bridge behind her.
She walked past some of UnLondon’s odd buildings. A house like a fruit with windows, one in the shape of the letter S and another like a Y, a house in a giant hollowed-out ball of string. It made the building that Brokkenbroll took them towards stand out all the more.
“I remember this place,” Mortar said. “Used to get supplies round the back, by canal…”
It was a perfectly ordinary-looking brick factory. It was several floors high, with a tall chimney-cum-clocktower rising from its heart.
28. The Laboratory
The Unbrellissimo led them through the building in absolute darkness.
They stumbled through corridors and rooms and up flights of stairs, following his voice.
“What if there are traps?” Lectern said.
“Shut up,” the book said urgently. “I want to hear this. I need to know what’s going on.”
“It’s been obvious for a while that the Smog’s been preparing something,” Brokkenbroll said. “The Smog’s always hidden, set the odd fire, rushed out and drunk it, disappeared again. Lurking in deserted buildings or under the ground. But things have been changing.
“People have been wondering for months now if the Shwazzy’s due. I think that’s what’s got the Smog so nervous. It must think it’s quest season.
“It was obvious that Unstible was worried, though. I don’t think…” Brokkenbroll looked momentarily at the book, then away, seemingly embarrassed. “I’m not sure he ever quite believed the prophecies were true.” (“Might have been sensible,” the book said morosely.) “When I heard he’d gone, it made me think. Perhaps he was right. Just in case the Shwazzy didn’t come…I thought Unstible was onto something. UnLondon needs a backup plan.”
They kept on through the building’s windowless, unlit innards. Deeba heard Curdle sniff its way.
“Something occurred to me,” the Unbrellissimo said. “The bullets that the Smog fires: they’re rain. An aggressive kind of rain, but rain all the same. The Smog’s a cloud. And clouds have one natural enemy. The unbrella.”
“Hang on,” Deeba said. “Your umbrellas are broken.”
There was an awkward silence.
“Your umbrellas are sticks,” Brokkenbroll said coldly. “My unbrellas are awake. And still protectors. So I decided to train them, with a little finessing, to protect UnLondoners.
“I needed an army. It wouldn’t be enough to rely on the discards that usually dribble through. So I’ve been recruiting. All the way from here.
“Then I heard something had happened. I listen to the gossip of clouds, which come and go between this sky and yours, and they said the Smog was cackling, that it had defeated its enemy. I wondered if something had happened to the Shwazzy. So I called a watcher to check. Hoped the information was wrong. That’s what you saw, young lady.”
“Zanna didn’t get hit,” said Deeba. “It was another girl.”
“Ah…” said Brokkenbroll. “Blond? Tall? That explains the confusion. I was under the impression that the Shwazzy had been incapacitated. Which, sadly, has now turned out to be true. So it’s just as well I’ve been preparing, after all.”
There was a faint light in the hallway. Brokkenbroll stood by the outline of a door.
“But how?” said Deeba. “Umbrellas can’t stop bullets.”
“Please,” hissed Mortar. “You’re being rather brusque.”
“Leave her alone, Mortar,” Lectern muttered. “What our visitor is trying to say, Unbrellissimo, is that, uh…”
“She’s absolutely right,” Brokkenbroll said. “Neither umbrellas nor unbrellas can stop bullets. Not untreated, they can’t. But as I say— the Smog’s bullets are just rain, and my subjects keep the rain off. I knew there must be ways of reinforcing them.”
“So they’re like bulletproof vests?” said Deeba.
“Almost. The problem is that the Smog can change its chemicals, can fire missiles in many different compounds. The only way to make unbrellas effective against anything it might produce was to know everything about the Smog.”
“So that’s why we’re here,” Deeba said. “You got into Unstible’s workshop and read his books, innit? He knew more’n anyone else, and you’ve been learning.”
“Smart girl,” murmured Lectern.
Brokkenbroll laughed.
“You flatter me,” he said. “I couldn’t make head or tail of those texts. Believe me, I’ve tried. No, I knew I’d need help from an expert.”
He opened the door. The illuminations in the room beyond made them blink.
It was an enormous workshop. The ceiling soared. There were shelves crammed with books and dusty machines, and flasks and scrolls and pens and junk. There were piles of plastic, and bits of coal. By a huge fireplace was a freight elevator.
The chamber was filled with boiling kettles and glass and rubber tubes, boilers and conveyor belts. In the center was a bubbling brass vat.
There were no windows in the room. The light came from an enormous number of placid-looking insects the size of Deeba’s fist, which sat on shelves and stools and crawled sluggishly up the walls. Their abdomens were lightbulbs, screwed into their thoraxes. Their slow motion made the shadows crawl.
