Mortal Engines

Dr Arkengarth told me how Pandora Shaw was murdered, and I’d already found out that she died seven years ago, around the time you got back from that expedition and the Lord Mayor was so pleased with you, so I just put it all together and. …”

She shrugged. The trail had been easy to follow once she had all the clues. She picked up a book she had been reading and showed it to him. It was Adventures on a Dead Continent, his own account of his journey to America. She pointed to a face in a group photograph of the expedition; an aviatrix who stood beside him, smiling. “I didn’t realize at first,” she said, “because her name had changed. Did you kill her yourself? Or did you get Pewsey and Gench to do it?”

Valentine hung his head, angry, despairing, ashamed. A part of Katherine had been hoping against hope that she was wrong, that he would deny it and give her proof that he was not the Shaws’ killer, but when she saw his head go down she knew that he could not and it was true.

He said, “You must understand, Kate, I did it for you…”

“For me?”

He looked up at last, but not at her. He stared at the wall near her elbow and said, “I wanted you to have everything. I wanted you to grow up as a lady, not as an Out-Country scavenger like I had been. I had to find something that Crome needed.

“Pandora was an old comrade, from the American trip, just as you say. And yes, she was with me when I found the plans and access codes to MEDUSA. We never imagined it would be possible to reconstruct the thing. Later Pandora and I went our separate ways; she was an Anti-Tractionist and she married some clod-hopping farmer and settled down on a place called Oak Island. I didn’t know she was still thinking about MEDUSA. She must have made another trip to America, alone this time, and found her way into another part of the same old underground complex, a part we’d missed on the first dig. That’s where she found—”

“A computer-brain,” said Katherine impatiently. “The key to MEDUSA.”

“Yes,” murmured Valentine, astonished at how much she knew. “She sent me a letter, telling me she had it. She knew it was worthless without the plans and codes, you see, and those were in London. She thought we could sell it and share the proceeds. And I knew that if I could give Crome a prize like that it would make my fortune, and your future would be secure!”

“And so you killed her for it,” said Katherine.

“She wouldn’t agree to sell it to Crome,” said her father. “She was an Anti-Tractionist, as I said. She wanted the League to have it. I had to kill her, Kate.”

“But what about Hester?” said Katherine numbly. “Why did you have to hurt her?”

“I didn’t mean to,” he said miserably. “She must have woken up and heard something. She was a pretty child. She was about your age, and she looked so like you that she might have been your sister. Perhaps she was your sister. Pandora and I were very close at one time.”

“My sister?” gasped Katherine. “Your own daughter!”

“When I looked up from her mother’s body and saw her staring at me! I had to silence her. I struck wildly at her, and I made a mess of it. I thought she was dead, but I couldn’t bring myself to make sure. She escaped, vanished in a boat. I thought she must have drowned, until she tried to stab me that night in the Gut.”

“And Tom…” Katherine said. “He learned her name, and so you had to kill him too, because if he’d mentioned her to the Historians the truth might have come out.”

Valentine looked helplessly at her. “You don’t understand, Kate. If people discovered who she is and what I have done, not even Crome would be able to protect me. I would be finished, and you would be dragged down with me.”

“But Crome knows, doesn’t he?” asked Katherine. “That’s why you’re so loyal. Loyal as a dog, so long as you get paid and get to pretend that foreign daughter of yours is a High London lady.”

Rain, rain on the windows and the whole room quivering as London dragged itself across the sodden earth. Dog lay with his head on his paws, his eyes darting from his mistress to Valentine and back. He had never seen them fight before, and he hated it.

“I used to think you were wonderful,” said Katherine. “I used to think that you were the best, bravest, wisest person in the world. But you’re not. You’re not even very clever, are you? Didn’t you realize what Crome would use the thing for?”

Valentine looked sharply at her. “Of course I did! This is a town eat town world, Kate. It’s a shame Panzerstadt-Bayreuth had to be destroyed, of course, but the Shield-Wall has to be breached if London is to survive. We need a new hunting ground.”

“But people live there!” wailed Katherine.

“Only Anti-Tractionists, Kate, and most of them will probably get away.”

“They’ll stop us. They’ve got airships…”

“No.” In spite of everything, Valentine smiled, proud of himself. “Why do you think Crome sent me east? The League’s Northern Air-Fleet is in ashes. Tonight MEDUSA will blast us a passage through their famous Wall.” He stood up and reached for her, smiling, as if this victory that he was delivering would put right everything he had done. “Crome tells me that firing is scheduled for nine o’clock. There’s to be a reception at the Guildhall beforehand; wine, nibbles and the dawn of a new era. Will you come with me, Kate? I’d like you to…”

Her last hope had been that he had not known Crome’s mad plan. Now even that was gone. “You fool!” she screamed. “Don’t you understand what he’s doing is wrong? You’ve got to stop him! You’ve got to get rid of his horrible machine!”

“But that would leave London defenceless, in the middle of the Hunting Ground,” her father pointed out.

“So? We will have to carry on as we always have, chasing and eating, and if we meet a bigger city and get eaten ourselves… well, even that would be better than being murderers!”

She couldn’t bear to be in that room with him another second. She ran, and he did not try to stop her, or even call her back, just stood there looking pale and stunned. She left the house and ran sobbing through the rainswept park with Dog at her heels, until the whole of High London was between her and Father. I must do something! was all she could think. I must stop MEDUSA…

She hurried towards the elevator station, while the Goggle-screen loops began to blare the good news of Valentine’s return all over London.

31. THE EAVESDROPPER

London gathered speed, racing towards the mountains. Semi-static towns that had hidden for years on these high steppes were startled out of their torpor by its coming and went lumbering away, leaving behind them green patches of farmland and once a whole static suburb. The city paid no heed to any of them. The whole of London knew the Lord Mayor’s plan by now. In spite of the cold, people gathered on the forward observation decks and peered through telescopes towards Shan Guo, eager for their first glimpse of the legendary Wall.

“Soon!” they told each other.

“This very night!”

“A whole new hunting ground!”

Most people at the Museum were used to Katherine and Dog by now, and nobody paid very much attention as she hastened through the lower galleries with the white wolf trotting behind her. A few noticed the frantic look in her eyes and the tears on her face, but before they could ask her what was wrong or proffer a pocket handkerchief she had swept past, heading towards Mr Nancarrow’s office at a near run.

There she found a smell of turpentine and the lingering scent of the art-historian’s pipe tobacco, but no Nancarrow and no Bevis Pod. She ran back out into the hallway, where a fat Third-Class Apprentice was mopping the floors. “Mr Nancarrow’s in the store-rooms, Miss,” he told her sullenly. “He’s got that funny new bloke with him.”
