He ran across Piccadilly and cut down a side street. His coat flapped, but he no longer concerned himself as to how cool it looked.

As he emerged onto Park Lane, he faced the gray space of Hyde Park. It was no longer still. It was moving, crawling like rotten meat.

There was no time for anything anymore. He ran toward Speakers Corner to find a crowd of people barely alive, staring in slack-jawed awe up at a bald-headed madman who had, for the occasion, smeared a circle of black grease on his forehead.

They came from Hyde Park, shambling from the open gates, dragging their emaciated legs to hear the prophet speak.

Petrovitch couldn’t get near him without pushing through the press of bodies. His heart was already skipping beats and fluttering behind his ribs, and he could feel the capacitors charging; the electric tension before the lightning. Then the prophet spotted him from his crate-top perch and declaimed:

“See? See the machine-man who gives and gets life: the true symbiote who does not fear the coming age!”

Charge raced through Petrovitch, and he fell to his knees. The pain was agony, the passing of it relief. He was dimly aware that he was staring at a pair of filthy feet shod only in sandals.

He swallowed the metallic taste in his mouth and looked up. The shaven-headed man with the oil mark looked down.

“Stand up, my brother. We are all equal beneath the machine.”

Petrovitch stood shakily. He would have put his hand out for support, but he was afraid of what he might touch.

“I…” He swallowed again. His mouth was desert-dry. “How did you know about this new machine jihad before everyone else?”

The prophet smiled. His teeth were yellow, rotting. “The Machine chose me to proclaim the new order. The Machine is one and many. I am but the first believer.” As he spoke, his eyes flickered, as if he was reading text from a page.

“How did it choose you?”

The man put his hand inside his shirt and brought out his mobile phone. He held it reverently as he would a relic. “I received its holy oracle.”

Petrovitch looked at the chipped, dented device. “Do you speak to it?”

“It speaks to me! I would not dare question the Machine.” He snatched the phone away as Petrovitch reached for it. “Are you worthy?”

“Yeah,” said Petrovitch, starting to lose his temper. “Just get God on the line. I hope he talks more sense than you.”

The prophet pressed two buttons: God was apparently now on speed-dial. He presented the phone with a bow. Petrovitch plucked it out of the man’s dirt-encrusted fingers and held it gingerly to his ear.

It was ringing.

Then, with a click, the line was live.

“Hello? It’s Petrovitch.”
