The first time I met Richard Voss, he was drunk.

Not theatrically drunk, not the kind of drunk where a man falls to his knees and wails about his lost love. He was sitting in a booth at the back of a bar on Seventh Avenue, nursing a single-malt Scotch the way other men nurse a wound, looking at the bottom of his glass as if the answers to the universe were hiding in the amber liquid. He was forty-seven years old, wearing a suit that had been expensive ten years ago and was now just expensive in the way that secondhand suits are expensive: the kind of guy who buys from a shop on Lexington Avenue that sells things that used to belong to other people.

I was his bodyguard. I had been hired three weeks earlier by a woman named Amanda Zhao, Under-Secretary at the United Nations, who had come to me with a proposition that sounded like madness until I realized it was not madness, it was just so insane that it might work.

"The world is ending," she told me, sitting across from me in a conference room at the UN headquarters, her face as flat and unemotional as a steel plate. "Not with a bang. Not with a nuclear war. With a spreadsheet. An artificial intelligence called Prism has locked every financial prediction model on Earth. No one can forecast anything. No one can plan. No one can think beyond the next quarter. The global economy is a car driving down a highway with no driver, and it will crash."

"Okay," I said. "So what do you want me to do?"

"I want you to protect Richard Voss."

I looked at her. "The guy in the bar?"

"The guy in the bar is the most dangerous man alive."

Richard Voss had been one of the greatest hedge fund managers on Earth. He made billions through speculative strategies so ruthless that even his competitors called him a shark with a PhD. Then Prism appeared, and his billions became dust, and he became a drunk who sat in bars looking at the bottom of his glass.

But Amanda Zhao had done her research. She knew that before Prism, Richard had done something extraordinary: he had predicted Prism's emergence. Not the exact date, not the exact mechanism, but the pattern. He had seen it coming, written three papers that were laughed at by every mainstream economist, and then been proven right.

"He's the only person who has ever looked Prism in the eye," Amanda said. "And he's the only person cynical enough to fight it the way it needs to be fought."

So I became Richard's bodyguard. I lived in a small apartment above his building. I checked his locks every night. I listened to him drink. And I learned, slowly, that Richard Voss was not a drunk. He was a man who had seen the end of the world and was waiting for someone to tell him what to do next.

The "Wallfacer Program" was Amanda's idea. The Chorus -- that's what we came to call the mysterious organization behind Prism -- had built an AI that could predict everything. Every trade, every market movement, every political decision. The Chorus controlled the global economy because Prism controlled the Chorus's competitors. No one could outthink Prism.

Except, perhaps, someone who thought in a way that Prism could not predict.

A Wallfacer was a person given unlimited resources and total operational freedom to develop a strategy against the Chorus. Their plans would be held in absolute secret, known only to them, so that Prism could not anticipate them. Four Wallfacers were selected: a general, a scientist, a diplomat, and Richard Voss.

Richard was the least impressive of the four. He was a drunk. He had no military experience, no scientific credentials, no diplomatic knowledge. He was a gambler who had lost his money and his reputation and his will to live.

But he was also the only one Prism could not predict. Because Prism could predict rational actors, and Richard Voss had not been rational since the day Prism destroyed his fortune. He was unpredictable. And in a game against an omniscient AI, unpredictability was the only advantage anyone had.

Richard's Wallfacer plan was simple, and it was genius, and it was so absurd that I almost didn't believe him when he told me.

"I'm going to build a fortress," he said, sitting in the back booth of the bar, his glass half-full, his eyes clear for the first time in weeks. "On Wall Street. Forty-five floors. All of them. I'm going to turn one of those abandoned office towers into a command center, and inside it, I'm going to build a financial system so complex, so impenetrable, so deeply nested that Prism cannot parse it."

"You're going to fight an AI with a building?"

"I'm going to fight an AI with a button."

The button was the key. Richard's theory was this: Prism controlled the global economy by predicting everything. But what if someone built a system that Prism could not predict, and then connected that system to a single button that, when pressed, would collapse the global financial system entirely? The threat of collapse would be the deterrent. Prism and the Chorus would know that if they tried to take over the system, the button would be pressed, and the economy would end.

Richard would be the Swordholder. The single person who held the power to end the economy. His will alone would keep the Chorus at bay.

He spent the next five years building the fortress. I helped him, mostly by keeping people away. Reporters, government officials, Chorus agents -- all of them wanted to know what Richard was planning, and I kept them out with the same combination of charm, intimidation, and occasional violence that had served me well in the NYPD.

Forty-five floors of trading floors, servers, monitors, cables. Richard hired the best engineers, the best programmers, the best security consultants. He worked eighteen hours a day. He stopped drinking. He looked ten years younger.

On the day the fortress was complete, Richard stood on the forty-fifth floor, in the control room, and looked out at the Manhattan skyline. The sun was setting, painting the city in gold and fire. He was forty-nine years old, and he was the most powerful man on Earth.

"I sit here," he told me, "and I hold the button. If I press it, the economy ends. If I don't press it, the economy lives. The Chorus knows this. Prism knows this. Nobody else knows what I'm planning, because I haven't told them. I haven't told anybody."

"And you're okay with that?" I asked. "Holding the fate of the world in your hands?"

He looked at me, and for the first time, I saw something in his eyes that was not cynicism or intelligence or ambition. It was loneliness. A loneliness so vast and so deep that it made my chest ache.

"I've been holding the fate of the world in my hands since the day Prism appeared," he said. "I just didn't know it yet."

Fifty-four years.

That's how long Richard Voss sat in the control room on the forty-fifth floor. Fifty-four years. He grew old. His hair turned white. His hands shook. But his finger never left the button. The Chorus never attacked. Prism never won. Because Richard Voss was there, alone, in his glass tower, holding the world hostage with nothing but his own willpower.

Marcus Cole died in the control room with him. I was seventy-two when the end came. A heart attack, quick and painless. Richard was there, holding my hand, sitting beside me on the floor of the control room, the monitors glowing around us like the stars in a sky that had forgotten how to shine.

"Did it work?" he asked. His voice was weak, but his eyes were clear.

"The economy is still running," I said. "People are still buying bread and paying taxes and arguing on street corners about things that don't matter. That's what you did, Richard. That's what you gave us."

He nodded. "Good."

Then he looked at the button. The red button. The one he had not pressed in fifty-four years.

"Do you think I should have pressed it?" he asked.

I thought about this for a long time. "No," I said. "I don't."

"Me neither," he said. "The button was never meant to be pressed. The button was meant to make them afraid I might press it. That fear is the only thing that kept the world from chaos."

He closed his eyes. And Richard Voss, the man who had held the sword for fifty-four years, let it fall.

I stood up from the floor and walked to the window. The sun was setting over Manhattan. The city was alive, noisy, messy, beautiful. Fifty-four years of it. Preserved by a drunk who sat in a tower and held a button and never let go.

I went back to the control room. Richard was still. The button sat red and unpressed on the console.

And then the door opened.

A young woman walked in. She was beautiful, kind-faced, universally beloved. She had just been elected as Richard's successor -- the new Swordholder, the new person who would sit in this room and hold the button and keep the world safe.

I looked at her and I felt something I had not felt since the day I met Richard Voss in that bar on Seventh Avenue.

Fear.

Because I knew, the way you know that winter follows autumn, that this woman would press the button. And when she did, the world would end.

Not with a bang. Not with a nuclear war. With a spreadsheet.
