They had come in a circle. The airship hung just ahead of them, and a giant shape barred their path. Two beams of pale green light stabbed towards them, filled with dancing water droplets. “HESTER,” grated a metal voice.
Hester groped for something she could use as a weapon and came up with a gnarled old length of wood. “Don’t come any closer, Shrike!” she warned. “I’ll smash those pretty green eyes of yours! I’ll bash your brains out!”
“Come on!” squeaked Tom, plucking at her coat and trying to drag her away.
“Where to?” asked Hester, risking a quick glance back at him. She shifted her grip on the makeshift club and stood her ground as Shrike stalked closer.
“YOU HAVE DONE WELL, HESTER, BUT THE HUNT IS ENDED.” The Stalker was moving carefully over the wet ground. Each time he set down his metal foot a wreath of steam hissed up. He raised his hands and claw-like blades slid out.
“What made you change your mind about London, Shrike?” shouted Hester angrily. “How do you come to be Crome’s odd-job man?”
“YOU LED ME TO LONDON, HESTER.” Shrike paused, and his dead face widened in a steely smile, “I KNEW YOU WOULD GO THERE. I SOLD MY COLLECTION AND CHARTERED AN AIRSHIP SO THAT I COULD GET THERE BEFORE YOU.”
“You sold your clockwork people?” Hester sounded astonished. “Shrike, if you wanted me back that badly, why didn’t you just track me down?”
“L DECIDED TO LET YOU CROSS THE HUNTING GROUND ALONE,” said Shrike. “IT WAS A TEST.”
“Did I pass?”
Shrike ignored her. “WHEN I REACHED LONDON I WAS TAKEN STRAIGHT TO THE ENGINEERIUM, AS I EXPECTED. 1 SPENT EIGHTEEN MONTHS THERE WAITING FOR YOU TO ARRIVE. THE ENGINEERS TOOK ME APART AND PUT ME TOGETHER AGAIN A DOZEN TIMES. BUT IT WAS WORTH IT. I MADE A DEAL WITH MAGNUS CROME. HE HAS PROMISED ME MY HEART’S DESIRE.”
“Oh, good,” said Hester weakly, wondering what on earth he was talking about.
“BUT FIRST YOU MUST DIE.”
“But Shrike, why?”
The reply was drowned out by a thick, warbling hum that made Tom wonder if the Stalker’s airship was about to lift off without him. He glanced up at it. It was still holding the same position as before, but the steady chirrup of the propellers had been masked by the new noise, a rumbling, slithering roar that grew louder every second. Even Shrike seemed disturbed: his eyes flickered and he tilted his head to one side, listening. Underfoot, the ground began to tremble.
Out of the fog behind the Stalker burst a wall of mud and water, curling over at the top, capped with white foam. Behind it came a town, a very small, old-fashioned town, racing along on eight fat wheels. Hester scrambled backwards, and Shrike saw the look on her face and turned to see what caused it. Tom dived sideways, grabbing the girl by the scruff of her neck and hurling her to safety. The airship tried to veer away but the wheels of the speeding town caught it and blew it apart and ploughed the blazing debris down into the mud. An instant later they heard the Stalker bellow “HESTER!” as the huge front wheel came crashing down on him.
They clung together, rolling over and over as the town howled past, a flicker of spokes and pistons, firelight on metal, tiny figures staring down from observation decks, the long-drawn-out moan of a klaxon echoing through the fog. Then, just as suddenly as it had appeared, it was gone. The air stank of smoke and hot metal.
They sat up. Bits of airship were drifting down, blazing merrily. Where the Stalker had been standing a deep wheel-mark was quickly filling with black, glistening mud. Something which might have been an iron hand jutted from the ooze and a pale cloud of steam rose into the air above it and slowly faded.
“Is it… dead?” asked Tom, his voice all quivery with fright.
“A town just ran over him,” said Hester. “I shouldn’t think he’s very well…”
Tom wondered dimly what Shrike had meant about his “heart’s desire”. Why would he have sold his precious collection to come after Hester if all he wanted to do was kill her? There was no way of knowing now. “And the poor men on that airship…” he whispered.
“They were sent to help him kill us, Natsworthy,” said the girl. “Don’t waste your pity on them.”
They were quiet for a moment, staring at the mist. Then Tom said, “I wonder what it was running from?”
“What do you mean?”
“That town,” said Tom. “It was moving so fast… Something must be chasing it…”
Hester looked at him and slowly realized what he meant.
“Oh, knackers!” she said.
The second town was upon them almost at once. It was bigger than the first, with vast, barrel-shaped wheels. On its gaping jaws some wag had drawn a toothy grin and the words, “HAPPY EETER”.
There was no time to run out of its way. Hester grabbed Tom this time and he saw her shouting something, but the shrieking thunder of the engines meant that it took him a moment to work out what it was.
“We can jump it! Do as I do!”
The town rolled over them, its wheels passing on either side so that they were lifted up like two ants in the path of a plough, lifted on a wave of mud that almost smashed them against the lumbering metal belly overhead. Hester crouched on the crest of the wave like a surfer and Tom wobbled beside her, expecting at any moment to be swatted out of his life by a passing derrick or hurled under the wheels. Hester was shouting at him again, and pointing. An exhaust duct was rushing past them like a monstrous snake, and by the flare of furnace-light from vents on the town’s underside he made out the handrail of a maintenance platform. Hester grabbed at it and swung herself up, and Tom flung himself after her. For a moment his hands clutched wildly at nothing, then there was rusty iron under his fingers, almost jerking his arms from their sockets, and Hester reached down and took a firm grip on his belt and hauled him to safety.
It was a long time before they stopped shaking and clambered to their feet. They both looked as if they had been modelled crudely from the Out-Country mud; it covered their clothes and clagged in their hair and plastered their faces. Tom was laughing helplessly at the closeness of their escape and at the sheer surprise of finding himself still alive, and Hester laughed with him. He had never heard her laugh before, and he had never felt as close to anyone as he felt to her at that moment.
“We’ll be all right!” she said. “We’ll be all right now! Let’s go up and find out who we’ve hitched a lift with!”
* * *
Whatever the town was, it was small, only a suburb really. Tom amused himself by trying to work out what it might be while Hester picked the lock on a hatchway and led him up a long stairwell with rusty walls that steamed in the heat from the engines. He thought it looked a bit like Crawley, or Purley Spokes, the suburbs that London had built back in the great old days when there was so much prey that cities could afford to build little satellite towns. If so, it might have its own merchant airships, licensed to trade with London.
But something still nagged at the back of his mind. Only the most foolhardy mayor would bring his town here…
Why on earth would Crawley or Purley Spokes be chasing a townlet into the dreaded Rustwater Marshes?
They climbed on up the stairwell until they reached a second hatch. It wasn’t locked, and swung open to let them out on to the upper deck. A cold wind blew fog between the metal buildings and the deckplates shook and lurched as the suburb raced onwards. The streets seemed deserted, but Tom knew that small towns often had only a few hundred inhabitants. Perhaps they were all busy in the engine-rooms, or waiting safe indoors until the chase was over.
But there was something about this place he didn’t like; it certainly wasn’t the trim little suburb he had been hoping for. The deckplates were rusty and pitted and the shabby houses were dwarfed by huge auxiliary engines that had been ripped out of other towns and bolted haphazardly to this one, linked to the main engines on the deck below by a cat’s-cradle of gigantic ducts that wrapped around the buildings and burrowed down through holes cut in the de
ckplate. Beyond them, where Tom would have expected parks and observation platforms, a mess of gun-emplacements and wooden palisades ringed the edge of the suburb.
Hester motioned for him to keep quiet and led him towards the foggy stern, where he could see a tall building that must be the Town Hall. As they drew nearer they made out a sign above the entrance which read:
Welcome to
TUNBRIDGE WHEELS
Population: 500 467 212
and still rising!
Above it flapped a black and white flag; a grinning skull and two crossed bones.
“Great Quirke!” gasped Tom. “This is a pirate suburb!”
And suddenly, from foggy side-streets all around them, came men and women as shabby as the town, lean and hard and fierce-eyed, and carrying the biggest guns that he had ever seen.
* * *
As the pirate suburb speeds on its way, silence returns to the Rustwater, broken only by the sounds of small creatures moving in the reed-beds. Then the ooze in one of the deep wheel-ruts burbles and heaves and vomits up the jerking wreck of Shrike.
He has been driven far down into the mud like a screaming tent-peg, ground and crushed and twisted. His left arm hangs by a few frayed wires; his right leg will not move. One of his eyes is dark and blind and the view from the other is cloudy, so that he has to keep twitching his head to clear it. Bits of his memory have vanished, but others come up unbidden. As he wades out of the suburb’s wheel-marks he remembers the ancient wars that he was built for. At Hill 20 the Tesla Guns crackled like iced lightning, wrapping him in fire until his flesh began to fry on his iron bones. But he survived. He is the last of the Lazarus Brigade, and he always survives. It will take a lot more than being run over by a couple of towns to finish Shrike.
Slowly, slowly, he claws his way to firmer ground, and sniffs and scouts and scans until he is sure that Hester escaped alive. He feels very proud of her. His heart’s desire! Soon he will find her again, and the loneliness of his everlasting life will be over.
The suburb has left deep grooves across the landscape. It will be easy to track, even with his leg dragging uselessly, even with an eye gone and his mind misfiring. The Stalker throws back his head and bellows his hunting cry at the empty marshes.
16. THE TURD TANKS
London kept on moving, day after day, grinding its way across the continent formerly known as Europe as if there were some fantastic prize ahead—but all that the look-outs had sighted since the city ate Salthook were a few tiny scavenger towns, and Magnus Crome would not even alter course to catch them. People started to grow restless, asking each other in whispers what the Lord Mayor thought he was playing at. London had never been meant to go so far, so fast. There was talk of food shortages, and the heat from the engines spread up through the deckplates until it was said you could fry an egg on the pavements of Tier Six.
Down in the Gut the heat was appalling, and when Katherine stepped off the elevator at Tartarus Row she felt as if she had just walked into an oven. She had never been so deep into the Gut before, and for a while she stood blinking on the steps of the elevator terminus, dazed by the noise and darkness. Up on Tier One she had left the sun shining down on Circle Park and a cool wind stirring the rose-bushes: down here gangs of men were were running about, klaxons were honking and huge hoppers of fuel were grinding past her on their way to the furnaces.
For a moment she felt like going home, but she knew that she had do what she had come here for, for Father’s sake. She took a deep breath and went out into the street.
It was nothing like High London. Nobody knew her face down here; passers-by were surly when she asked them for directions, and off-duty labourers lounging on the pavements whistled as she went by and shouted, “Hello, darling!” and “Where’d you get that hat?” A burly foreman shoved her aside to lead a gang of shackled convicts past. From shrines under the fuel-ducts leered statues of Sooty Pete, the hunch-backed god of engine rooms and smoke-stacks. Katherine lifted her chin and kept a tight grip on Dog’s leash, glad that he was there to protect her.
But she knew that this was the only place where she could hope to find the truth. With Father away and Tom lost or dead, and Magnus Crome unwilling to talk, there was only one person left in London who might know the secret of the scarred girl.
It had been hard work finding him, but luckily the staff in the records office at the Guild of Salvagemen, Stokers, Wheel-Tappers and Associated Gut Operatives were happy enough to oblige Thaddeus Valentine’s daughter. If there was an Apprentice Engineer near the waste-chutes that night, they said, he must have been supervising convict labourers, and if he was supervising convict labourers he must have come from the Engineers’ experimental prison in the Deep Gut. A few more questions and a bribe to a Gut foreman and she had a name: Apprentice Engineer Pod.
Now, nearly a week after her meeting with the Lord Mayor, she was on her way to talk to him.
* * *
The Deep Gut Prison was a complex of buildings the size of a small town which clustered around the base of a giant support pillar. Katherine followed signposts to the administration block, a spherical metal building jacked up on rust-streaked gantries and slowly revolving so that the supervisors could look down from its windows and watch their cell-blocks and exercise yards and algae-mat farms spin endlessly around them. In the entrance hall, neon light glimmered on acres of white metal. An Engineer came gliding up to Katherine as she stepped inside. “No dogs allowed,” he said.
“He’s not a dog, he’s a wolf,” replied Katherine, with her sweetest smile, and the man jumped back as Dog sniffed at his rubber coat. He was prim-looking, with a thin, pursed mouth and patches of eczema on his bald head. The badge on his coat said, Gut Supervisor Nimmo. Katherine smiled at him, and before he could raise any more objections she showed her gold pass and said, “I’m here on an errand for my father, the Head Historian. I have to see one of your apprentices, a boy called Pod.”
Supervisor Nimmo blinked at her and said, “But… But…”
“I’ve come straight from Magnus Crome’s office,” Katherine lied. “Call his secretary if you want to check…”
“No, I’m sure it’s all right…” mumbled Nimmo. Nobody from outside the Guild had ever wanted to interview an apprentice before, and he didn’t like it. There was probably a rule against it. But he didn’t want to argue with someone who knew the Lord Mayor. He asked Katherine to wait and scurried away, vanishing into a glass-walled office on the far side of the hall.
Katherine waited, stroking Dog’s head and smiling politely at bald, white-coated passers-by. Soon Nimmo was back. “I have located Apprentice Pod,” he announced. “He has been transferred to Section 60.”
“Oh, well done, Mr Nimmo!” beamed Katherine. “Can you send him up?”
“Certainly not,” retorted the Engineer, who wasn’t sure he liked being ordered about by a mere Historian’s daughter. But if she wanted to see Section 60, he would take her there. “Follow me,” he said, leading the way to a small elevator. “Section 60 is on the underdecks.”
The underdecks were where London kept its plumbing. Katherine had read about them in her school books so she was prepared for the long descent, but nothing could have prepared her for the smell. It hit her as soon as the elevator reached the bottom and the door slid open. It was like walking into a wall of wet sewage.
“This is Section 60, one of our most interesting experimental labour units,” said Nimmo, who didn’t seem to notice the smell. “The convicts assigned to this sector are helping to develop some very exciting new ways of recycling the city’s waste products.”
Katherine stepped out, clamping her handkerchief over her nose. She found herself standing in a huge, dimly-lit space. Ahead of her were three tanks, each larger than Clio House and all its gardens. Stinking yellow-brown filth was dribbling into the tanks from a maze of pipes that clung to the low ceiling, and people in drab grey prison coveralls were wading chest-deep in it, skimming the surface with
long-handled rakes.
“What are they doing?” asked Katherine. “What is that stuff?”
“Detritus, Miss Valentine,” said Nimmo, sounding proud. “Effluent. Ejecta. Human nutritional by-products.”
“You mean … poo?” said Katherine, appalled.
“Thank you, Miss Valentine; perhaps that is the word for which I was groping.” Nimmo glared at her. “There is nothing disgusting about it, I assure you. We all… ah … use the toilet from time to time. Well, now you know where your … um . … poo ends up. ‘Waste not, want not’ is the Engineers’ motto, Miss. Properly processed human ordure makes very useful fuel for our city’s engines. And we are experimenting with ways of turning it into a tasty and nutritious snack. We feed our prisoners on nothing else. Unfortunately they keep dying. But that is just a temporary set-back, I’m sure.”
Katherine walked to the edge of the nearest tank. I have come down to the Sunless Country! she thought. Oh, Clio! This is the land of the dead!
But even the Sunless Country could not be as terrible as this place. The slurry swilled and shifted, slapping at the edges of the tanks as London trundled over a range of rugged hills. Flies buzzed in thick clouds beneath the vaulted roof and settled on the faces and bodies of the labourers. Their shaven heads gleamed in the dim half-light, faces set in blank stares as they skimmed the thick crust from the surface and transferred it into hoppers which other convicts wheeled on rails along the sides of the tank. Grim-faced Apprentice Engineers looked on, swinging long, black truncheons. Only Dog seemed happy; he was straining at his leash, his tail wagging, and every now and then he would look up eagerly at Katherine as if to thank her for bringing him somewhere with such interesting smells.
