The rain in Chicago didn't wash things clean. It just made the grime slicker.

Jack Mority sat in his office on South State Street, watching the water trace dirty paths down the windowpane, and tried to figure out why a dead man's widow was paying him to investigate his husband's murder. The check was made out to cash, for an amount that suggested the husband hadn't just been any scientist. He'd been someone important. Or someone who knew something important.

In Chicago, those were usually the same thing.

The husband's name was Harold Voss. Three months ago, he'd been working on the Celestial Defence Programme, some classified thing happening in underground bunkers beneath the Swiss Alps. Two months ago, he'd come back to Chicago and started drinking. One month ago, he'd fallen off a ladder in his own basement while trying to fix a leak he should have called a plumber for.

The official report said accident. The widow said murder. The amount of the check said she knew something the police didn't.

Jack lit a cigarette and read Voss's file. The man had been a nuclear physicist, worked on the lunar propulsion project—some insane scheme to build engines on the Moon's surface. The kind of project that made headlines for a week and then disappeared from public view, replaced by talk of the Sky Ring hanging over the Pacific like a luminous noose.

The Ring. Everyone called it that now. A ring five thousand kilometres wide, burning blue at its edges, moving slowly inexorably toward Earth. Its ambassador, a creature they called Fang, had come to Earth six months ago and announced that his people would consume the planet. Not out of malice. Out of necessity. Like a man eating bread because he's hungry.

Humanity had responded the way humanity always responded: by building bigger guns and pretending they'd work.

Jack's phone rang. He let it ring three times before picking up.

"Mr. Mority?" A woman's voice, gravel and smoke. "This is Viola Chen. I understand you're looking into Harold Voss's death."

"Who's asking?"

"Someone who thinks you're asking the wrong questions."

Jack took a drag of his cigarette. "Then tell me the right ones."

"There are no right questions. Only dangerous ones."

"Miss Chen, in this town, all questions are dangerous. That's why people pay me to ask them."

Silence on the other end. Then: "Come to the docks. Warehouse seven. Come alone. And bring an umbrella. The rain's worse tonight."

The phone went dead.

***

Warehouse seven was on the south side, where the streets were wider and the streetlights didn't work. Jack parked two blocks away and walked the rest of the way, his trench coat pulled tight against the rain, his .38 tucked into the back of his waistband.

Viola Chen was waiting inside, standing beside a table covered with photographs and documents. She was younger than he'd expected, maybe thirty, with sharp features and sharper eyes. She wore a dark suit that cost more than his car, and she looked at him the way a cat looks at a bird it's decided to play with.

"You came," she said.

"I don't usually turn down work that's already been paid for."

She smiled, but it didn't reach her eyes. "Harold Voss wasn't investigating the Ring. He was investigating the Sky Group."

Jack set his cigarette in an ashtray that was already full of other people's cigarettes. "The Sky Group?"

"A organization within the Celestial Defence Programme. They've been operating in secret for five years. Their leader is General Thomas Crawford—the man commanding the lunar propulsion project."

Jack picked up a photograph. It showed a group of men in suits entering a building with no sign. One of them was General Crawford. Another was a man Jack recognized from the news: an admiral in the Navy. A third was someone he didn't recognize—tall, reptilian features, wearing a human suit that fit poorly around the shoulders.

Jack put the photograph down slowly. "Is that—?"

"Fang's real name is Darian," Viola said. "He's not just the Ring's ambassador. He's the Sky Group's partner."

Jack felt the cigarette pause halfway to his mouth. "Partner in what?"

"In a plan to transfer humanity's elite off-Earth. The lunar propulsion project isn't building weapons. It's building lifeboats. But not for everyone. For the people the Sky Group has selected—scientists, engineers, artists, anyone deemed valuable enough to save."

"Saved by whom?"

"By the Ring. By Darian's people. They're going to eat Earth, Mr. Mority. But they're going to spare the people the Sky Group sends them."

Jack looked at the photographs again. The dead man's face stared back at him from a dozen angles. Harold Voss, alive and dead, smiling and frowning, standing in labs and walking down streets and falling off ladders.

"Why was he killed?" Jack said.

"Because he found out the truth." Viola's voice was flat, matter-of-fact. "The lunar impact plan—the one where we aim the Moon at the Ring—that's not a defence strategy. It's a cover. A flag operation. While the public believes we're building weapons, the Sky Group is building a ship. A big one. Hidden in the debris of the 'propulsion engines' that kept failing."

Jack lit another cigarette. His hands were steady, which surprised him. "And Voss?"

"Voss was a man of science. He noticed discrepancies in the propulsion project's budget. Materials that were ordered but never used. Constructions that didn't match any known design. He dug deeper, and he found the ship. And when he told his wife what he'd found, she called someone. Someone who made sure he fell off a ladder."

Jack was quiet for a long time. The rain tapped against the warehouse roof like fingers on glass.

"Why tell me this?" he said finally.

"Because the impact is scheduled for seventy-two hours from now. And when the Moon hits the Ring, the Sky Group will use the chaos to evacuate their selected passengers. You need to tell someone. The public. The press. Anyone."

"And if I do," Jack said, "what happens to the people on the ship? To the people who stay behind?"

Viola's expression didn't change. "The people on the ship survive. The people who stay behind... well. The Ring eats planets. That's what it does."

***

Jack spent the next two days walking a razor's edge. He visited three journalists, two politicians, and a priest. None of them would act. The Ring was too big, too distant, too inevitable. What was one more conspiracy in a world that was already ending?

On the second night, he stood on the balcony of his apartment and watched the Ring hang in the sky, luminous and vast, its inner wall a city of lights that stretched beyond the horizon. It was beautiful, in the way a storm is beautiful. The way a grave is beautiful.

His phone rang. He knew who it was without looking at the number.

"Mr. Mority," Darian's voice said, translated through a crude machine into a man's voice that was deeper and rougher than human. "I understand you have information about the Sky Group."

"I have a lot of information."

"Would you like to trade it?"

"For what?"

"Survival."

Jack looked at the Ring. He thought of Harold Voss, falling off a ladder. He thought of Viola Chen, standing in a warehouse full of photographs. He thought of the people on the ship, floating away into the dark while Earth burned.

"What's the deal?" Jack said.

"The impact proceeds. The Ring is damaged. In the chaos, the Sky Group evacuates their passengers. You do not expose them. In exchange, I give you a place on the ship."

Jack was silent. The cigarette in his hand burned down to the filter.

"And the people who stay?" he said.

"Are consumed. That is the nature of the Ring. It eats planets. It does not ask permission."

Jack looked at the city below him, the streets slick with rain, the neon signs flickering in the dark. He thought of the people in those buildings, sleeping and drinking and loving and hating, completely unaware that their world was hanging by a thread and the hand holding that thread was about to cut it.

"No," Jack said.

There was a pause on the other end. "No?"

"I don't make deals with monsters, Mr. Darian. Or dinosaurs. Or whatever you are."

"Then you will die. And your death will mean nothing."

"Maybe," Jack said. "But at least I'll have chosen how I face it."

He hung up the phone.

***

The impact happened at dawn.

Jack stood on the lakefront, watching the Moon accelerate across the sky, its surface blazing with nuclear fire as five million weapons detonated in sequence. The recoil pushed the Moon along its curved trajectory, a silver eye opening in the daytime sky, blinking once, twice, three times, and then—

The Ring maneuvered.

Jack saw it on the news feeds, the Ring shifting its orbit, trying to slip past the oncoming Moon like a horse sidestepping a whip. For a moment, it looked like it might work. The distance closed: one hundred thousand kilometres, fifty thousand, thirty thousand—

And then the Ring tore.

A crack appeared on its hull, five thousand kilometres long, glowing red at its edges. Then another. Then another. The Ring's structure was failing, its self-rotation engines engaging too late, unable to brake the spin that the stress had induced.

On the screens, people cheered. Strangers hugged on the lakefront. Someone played a trumpet. Jack didn't cheer. He felt nothing, which was worse than feeling something.

Because he knew what was coming.

The Ring's engines re-lit. It began to return to its original position, slowly, carefully, re-establishing its orbit with Earth. It was walking a tightrope, and it was walking it successfully. The Moon had wounded the Ring, but the wound was not fatal.

Earth would still be consumed.

Jack went back to his office and made one phone call. He called the only journalist who hadn't hung up on him, a young man named O'Brien who worked for the Tribune and still believed in the truth the way other men believed in God.

"I have a story for you," Jack said. "It's about the Sky Group. It's about General Crawford. It's about Darian. And it's about a ship being built on the far side of the Moon."

"Where do I start?" O'Brien asked.

"Start with the fact that the people building that ship know exactly what's coming. And they're not telling anyone."

***

The story ran on the front page the next morning. It didn't change anything. The Ring kept coming. The Sky Group kept building. The world kept turning, indifferent to truth or lies.

Jack sat in a bar on State Street three weeks later, watching the news, drinking a beer that tasted like watered-down regret. The bartender was playing jazz on the radio—Louis Armstrong, singing about a world that was gonna roll again.

Jack didn't believe it was going to roll again. He believed in only one thing: that when the end came, he'd faced it on his own terms.

That had to be enough.

The door opened. A woman walked in, shook rain from her coat, and sat at the bar. Jack recognized her from the photographs. Viola Chen.

She turned, saw him, and walked over.

"You published the story," she said.

"I did."

"Did it help?"

Jack looked at his beer. "No."

Viola sat down beside him. "I have a proposition."

Jack looked at her. "I don't make deals with monsters."

"This isn't a proposition from the Sky Group. Or from Darian. It's from me. I'm leaving on the ship. And I want you to come with me."

Jack was quiet for a long time. Then he said, "Why?"

"Because you're the only person I know who asked the right questions and didn't like the answers. And because someone has to remember what happened here. Someone has to tell the story."

Jack looked at the television above the bar. The Ring filled the screen, luminous and vast, its engines burning blue. It was beautiful. It was terrible. It was inevitable.

He finished his beer. Set the glass on the bar. Stood up.

"Give me five minutes," he said.

He went back to his office, wrote a letter he knew would never be delivered, and left it on his desk. Then he walked back to the bar, pulled on his coat, and followed Viola Chen out into the rain.

The rain didn't wash anything clean. But it was honest. It fell on the righteous and the unrighteous alike, and it didn't pretend to be anything other than water.

Jack Mority stepped into it and didn't pull his coat tight.
