It was Petrovitch’s turn to look completely blank. He covered his confusion by draining every last drop of sake in his cup. “So if I said the words New Machine Jihad to you, it would mean nothing?”

“How did you hear of that?” Again, he looked amused, as if it were a matter of no consequence.

“The New Machine Jihad is the name of the… thing that’s destroying the Metrozone. But when I called it Oshicora-san, it answered. The New Machine Jihad is you.”

Oshicora shook his head. “No. That is simply not possible, and I will explain to you why. There is no connection between VirtualJapan and the wider network. This world is a bubble, sealed off for the moment. No data will get in or out until it is completely ready.”

“You can say that, but I know it’s not true. Why would the Jihad tell me that the shinkansen would run again? Why would it tell me to save Sonja? Why would it remember the promise you made to me? Why would it do any of these things if it wasn’t you?” Petrovitch stared hard at Oshicora’s faint smile. “So you have heard of the Jihad.”

“I dreamed of it, of a world where there was a revolution in technology: a new machine age.” He raised his eyebrows. “I had never expected to dream.”

“What else?”

“I dreamed of Oshicora’s daughter. And I dreamed of you. And a city, not like this one,” and he looked around him at the dark wood and burnished chrome, “but one made of steel and concrete, alive with movement and noise.”

Petrovitch understood at last. “Okay. What if I were to say to you that it’s your dreams that are leaking out into the real world? Your subconscious is running out of control, trying to create Tokyo from the ruins of the London Metrozone. Did you ever want to drive a train when you were younger?”

“Of course. I still do.”

“That little fantasy nearly killed me. You drove an express train at full speed into St. Pancras station while I was walking along the track. How about Sonja? How do you feel about her?”

“Protective. She is my creator’s child.”

“It’s more than that. You think she’s your daughter. Not up here,” Petrovitch said, tapping his head. He moved his hand to cover his heart. “but here. You told me to save her. I’ve rescued her from Sorenson, lost her to Chain, only to get her back from Hijo. And if I could, I’d show you what’s happening outside the tower. How it’s surrounded by water, choked with bodies and thick with rats feeding on the corpses. How there are fires everywhere, vast slices taken out of buildings as your monsters tear up the city. Oshicora-san, you might be sane in here, but out there, the New Machine Jihad is mad.”
