“And then there’s the Spike, and Perdido Street Station. You-know-who has to spend a lot of time in the Spike. Commanding the militia. Or in the station. In the embassy wing, in the high-tower.” It was more than the hub of New Crobuzon’s trains. It was a town, in three dimensions, encased in brick. The vastness of its mad-made architecture disobeyed not only rules of style but, it was said, of physics.

“When our quarry’s there, it ain’t as if it’s just the Perdidae we got to face.” Not that they would be easy to defeat. The dedicated submilitia given over to protect the station were well-armed and trained. “Wherever the chair-of-the-board goes, the Clypeans go. They’re our worry.

“What about in town? When did you last see any Fat Sun bigwig give a speech? They’re too scared, too busy trying to make secret peace with Tesh. So we need another strategy.” There was a long quiet.

“You-know-who is very close, intimate with one particular magister. Magister Legus. Weekly they meet. There’s all rumours, if you know who to ask. At Legus’ private house. Where he lives as a citizen, takes off his mask. They settle down in private. Sometimes they don’t part again until the morning.

“Happens every week, sometimes twice. In the magister’s house.

“The house next door.”

Tumult. How do you know ? someone was shouting, and You can’t, and Whose is this place? How did you get this? and on.

Ori had a memory. Something in him flinched from an understanding, unsettling, that veered close and was gone again and then was back. Ori saw others remembering, not sure what it was they remembered, not threading things together.

“It was hard to find out the true name behind a nom de jure,” Toro was saying. “But I did it. Took me a long time. Tracked him down.” Ori heard through gauze.

“This is the house…” Ori said, and then said nothing more. No one heard him and he was glad of that. He did not know what he wanted to do. He did not know what he felt.

This is the house where the old couple lived. That I heard about, the job you did, months ago, soon after I gave you the money. That the papers railed at. You killed them, or Old Shoulder did or one of us, and it weren’t that they was militia at all. They was rich, but you wouldn’t do them for that. It weren’t because they was rich but because of where they lived. You needed them gone so you could buy this house. That’s what you did with Jacobs’ money.

Ori felt gutted. He swallowed many times.

He sat hard on his own instincts. Something welled in him. All the uncertainty, the desperate lack of knowledge, then the weight of knowledge but vacillation of ideas, the shameful hash of theory that had sent him to the Runagaters, to all the different sects and dissidents, looking for something to ground him, a political home, which he had found in the anger and anarchist passion of Toro. His uncertainty came back. He knew what he felt-that this was a dreadful thing, that he was aghast-but he remembered the exhortations to contextualise, always to have context, that the Runagaters above all had always stressed.

If one death’ll stop ten, ain’t it better? If two deaths’ll save a city?

He was still. He had a sense that he did not know best, that he had to learn, that he was a better man in this collective than out, that he must understand why this had happened before he judged. Toro watched him. Turned to Old Shoulder. Ori saw the cactus-man set his face. They can see I know.

“Ori. Listen to me.”

The others watched without comprehension.

“Yes,” Toro lowed. Ori felt like a schoolchild before a teacher, so disempowered, so ill-at-ease. He felt truly sick. Toro’s thaumaturged drone felt through his skin.

“Yes,” Old Shoulder said. “This is the house. They were old, rich, alone, no one to inherit, it’d be sold. But no, it ain’t good. Don’t presume, Ori, that there’s no guilt and pain.

“We get in that house beside us… we’re done. We win. We win. ” Under the cactus’s words, Toro began to roar. It was a sound that went from beast-noise to the cry of elyctricity and iron under strain. It lasted a long time, and though it was not loud it took over the room and Ori’s head and stopped him thinking until it ebbed again and he was staring into Toro’s phosphorescent glass eyes.

“If we win, we take the city,” Old Shoulder said. “Take off the head. How many do we save then?” One by one, the other Toroans were understanding.

“You think other things weren’t tried? The magister’s house is closed. We can’t lie in wait there. The boss can’t push in, even with the horns. Some ward blocks us. Weapons won’t go through: not a bullet, a blast, a stone. It’s packed hard with charms. Because of who comes to visit. The sewers are stuffed with ghuls-no way in there there. It’s what we had to do. Think about it. You want out of this, now?”

How did I become the one to be asked? Don’t the others have to decide? But they were looking to him. Even Enoch had come to it now, and was open-mouthed thinking of what he had acted as lookout for, that night. Old Shoulder and Baron watched Ori. Tension drew the cactus-man up and stiff. Baron was relaxed. They would not let Ori walk, of course. He knew that. If he did not go along with this, he was dead. Even if he stayed, perhaps. If they thought they could not trust him.

Everything that was necessary was necessary. It was a tenet of the dissidents. And yes of course that necessary had to be fought over, debated and won. But they were so close. That they had found egress to a place their target would be alone, unwarded, vulnerable, where they could finally give their gift to New Crobuzon, was a towering thing. If it took two deaths to make it happen… could Ori stand in the way of history? Something in him blenched. It was necessary, he thought. He bowed his head.

On the top floor, the wall adjoining Magister Legus’ property had been precisely excavated. Inches of plaster and thin wood were swept away. The wall was dug out.

“Deeper’n that, hexes kick in,” Old Shoulder said. He touched the exposed surface with tremendous care. He was looking at Ori. Ori made his face unmoving. He listened. Toro had been preparing for weeks. Do you have other gangs? Ori thought, with an emotion he could not come close to identifying. Or are we your only ones? Whose name is this house in? It ain’t as if you bought it as yourself, is it?

Baron was talking, with his instrumental precision. I better listen, Ori realised. This is the plan.

“Sulion’s close to caving. We’re buying two things: information, of who’s where and what their tactics are, and a first move. Without him at the door, we’re dead.”

This is militia techniques, Ori thought, that’s what I’m learning. Once again, Ori wondered how many militia there were who had been to the war and had come back with such bitterness as this, so full of it. What they would do. He watched Baron and realised that everything in Baron led him to this, that he had no plans beyond this, that this would be his revenge.

An epidemic of murders. That’s what we’ll see. If those AWOL and back from the wars don’t have outlets. And the New Quill will recruit, too. They’ll recruit men like this. Jabber help us. And Ori’s eagerness to take off the head of the government came back strong. Soon, he thought. Soon.

He felt as if he might lose himself. He had to tell himself several times, until he was sure of it, that he was where he was meant to be.
