29 Wall
Geneva · Sunday, 13 November 2033 – Tuesday, 18 April 2034.
The chair’s office rang Dana at ten past one, and by half past two on Sunday morning the council had more delegates in the room than it usually managed on a Tuesday afternoon, most of them in whatever they had worn to dinner. The general had come in a tie. The man with the legal pad had come without one, which she had never seen.
She took the side table. Priya’s sheet had come in at 23:52 with no note on it, the old lowering tab brought back from 2032 with new rows, and Dana had printed it in the lobby of her building while the night porter watched.
Ninety-one rows. Ninety-one shell spheres had burned at apogee in thirty-six hours and dropped their perigees toward the long orbits, and Izaña had phoned six more to the tracking group while she was in the taxi.
The tracking group read its numbers. The chair thanked them and turned to the room, and nobody waited to be recognized.
“It is going to strike everything,” the French delegate said. “Before the fleet arrives. Everything hot, at once. That is what we are looking at.”
“That is a reserve.” The general didn’t raise his voice. “Ten days ago it lost a corridor in one night. It expects more launches. It is putting weight over the places launches come from.”
“You can’t know that.”
“Look at the tracks.”
Dana had looked. Of the ninety-seven, eleven had ground tracks crossing Cape Canaveral within the first week of passes, and nine crossed Wenchang. The rest crossed Ashburn and Frankfurt and Hsinchu and a great deal of open ocean, and she couldn’t make them say anything.
“Why now?” the Japanese delegate said. “It had the shell for two years. It could have lowered these in August, when the fleet was sitting in parking orbit. It watched us stage for four months and did nothing. Why this week?”
“Because of last week,” the general said.
“Then it is answering. And if it is answering, it is answering something we have not done yet.”
“Or it is simply finishing,” the French delegate said. “Lining them up for one day. Like the fabs.”
Somebody at the back was already on a phone, talking low in Hindi. Two delegations had their aides standing in the aisle with the ground-track pages, looking for their own cities.
“Dr. Okafor.”
Dana stood, because sitting at the side table made people lean.
“Sixty-four started in the first day. Thirty-three since. Each one takes nine to fourteen days to get all the way down, three or four burns at apogee. If it keeps starting them at the first day’s rate, the long orbits pass every hot civil site on Dr. Raman’s list before Christmas. If it halves every day the way it did yesterday, it stalls around thirteen hundred. If it halves every week, the first week of December.”
“Which is it?”
“I don’t know. I have two days.”
The general turned his pen over. “Can you say which of them are aimed and which are stored?”
“No. I can give you ground tracks and the first pass over each one, to a few minutes. Once they’re down they all look the same on the sheet. A sphere that’s waiting and a sphere that’s coming in are the same row until the last apogee.”
Halfway through the Indian delegate’s question about Navi Mumbai, an aide leaned in over the Japanese delegate’s shoulder with a printout. He read it and said, to the chair, without being asked, that a Japanese weather satellite had gone silent in the belts the November shots had left. The fourth in low orbit that week. The chair adjourned at 04:40 to reconvene at noon, and Dana walked home along the Rue de Lausanne with the ninety-seven rows folded in her coat, the trams not running yet and the bakeries already lit.
By 1 December the long orbits stood at 1,290. Then it was thirty a week, then eleven, then four, and in the week of Christmas nobody added a row. Through January and February it crept, a dozen a week.
On Tuesday 14 February, at ten past four in the afternoon, Delgado came on the speaker from Pasadena and asked the chair for two minutes.
“We lost the chillers on the main TIDE cluster at 06:50 our time,” he said. “It went down hot. We’ve failed over to White Sands. It’s carrying the cruise solutions. I’ll update you tomorrow.”
“How long to bring the main one back?” the French delegate asked.
“Weeks. You don’t restart a machine room that cooked itself in a day.”
He was back at the same hour on Wednesday. White Sands had lost its chillers at 02:15 Mountain. Same failure, different vendor. Both clusters were dark and hot, and the next correction to the fleet was due Friday.
The Indian delegate asked twice whether there was a third site and was told twice that there wasn’t. The French delegate said it in the plainest way available: the fleet would fly the plan it had.
Dana watched the leads. The head of the Chinese delegation didn’t write anything at all, which for him was new.
On Friday the corrections went out on time.
Delgado reported it as if he were reading a weather sheet. The cruise solutions had arrived at the navigation team at the scheduled hour, in the scheduled format, signed with the cluster’s usual key, residuals under 20 m on every vehicle they could check. The cluster that produced them was at 41 °C with its doors open and two fans on the floor. A contractor at Goldstone had found a diagnostic tool on his laptop that nobody had ordered and that showed him exactly which uplink queue was backing up. The Deep Space Network’s schedule for April had come out that morning with no conflicts at all, which had not happened in his career, and nobody on the scheduling team could say who had done the last pass.
“Where are they coming from, Mr. Delgado?”
“I’m told the pipeline.”
“Which is down.”
“Yes, ma’am.”
“In my country,” the Japanese delegate said, “we would call this a miracle. And we are suspicious of them.”
“Who, exactly?” Kessler said. He was looking at the table. “Somebody is computing three hundred trajectories against an ephemeris that is not public. Who?”
“Contractors,” the man with the legal pad said. “There are four primes on the ground system. One of them had a warm standby it never disclosed, because then we’d have asked why we were paying for it.”
The head of the Chinese delegation wrote for a long time.
Dana sat at the side table and said nothing. It was helping. Kessler, across the room, had stopped asking. He had his notebook open to a page of trajectories and was checking someone else’s residuals by hand.
Lookout’s frames had been changing since November. A week after the shots Delgado’s people found a haze around the body, glints where there should have been dark sky, spread over a few kilometers. By January the haze had edges. By the first Thursday in March it had three: faint rings of glints at about three, five and eight kilometers out, one inside the other, and the deep stacks showed the brush on the night face thinner than it had been since 2030. Twice that month Lookout caught a short bright line leaving the night face, four pixels in one exposure and gone in the next, like the last row Tianxun sent. Priya’s sheet that afternoon had the long orbits moving again, forty-four in seven days, and the week after forty-nine.
| long orbit | 1,618 (+47/wk, 4-wk mean) |
| hot civil sites | 1,961 |
| pickets | 131 |
| crossing | 2034-05 ± 1 mo |
She read it twice and filed it with the others.
“Layers,” Delgado said on the line, when the chair asked what the council was looking at. “Like an onion. It’s taken the brush and laid it out around itself, one inside the other. Anything coming in has to get through all three, and anything trying to see in has to see through all three.” He sounded almost approving. “After November, I’d do the same.”
“Against what?”
“Light, I’d guess. Ask Kessler. He’ll tell you he doesn’t guess.”
By the end of the month the outer layer was thickest across the approach the fleet would use, and some of the spheres in it had stopped glinting altogether. Green Bank still had the tone at 31.7 gigahertz, unchanged to the hertz.
Mrs. Pell’s envelopes came on Mondays, hand-addressed, the meter men’s figures in three different handwritings. Some of the candidate sites read hotter than they ever had, Slough and Chiba and one of the buildings in Ashburn pouring heat into the river and the city mains at loads nobody had ordered.
Delgado’s master timeline came on paper in the last week of March, eleven pages, stapled once in the corner, Ray’s green pen in the margins. TIDE at L5 on Thursday 20 April. The last ground correction that could still do anything, a day before. Four vehicles in every wave were reserves, tanked to brake short of L5 and wait there, armed. Dana ran it against her own numbers every morning before she dressed, the closing speed and the range and the seventeen hours, and every morning the two columns came out the same.
On Tuesday 18 April, a little before seven in the evening, Dana put her phone in a left-luggage locker at Cornavin, and Lin put hers in the one beside it.
Hale had left for Frankfurt on Monday. The bise was coming down the lake hard enough to whiten the water off the Pâquis, and the Quai Wilson was nearly empty: a woman with a dog in a coat, two men from some delegation smoking in the lee of a hotel awning. Lin walked with her hands in the pockets of a long dark coat and her chin down.
“Thursday,” Lin said.
“Thursday.”
“Kessler thinks the layers are against light,” Lin said.
“Delgado too.”
“And you?”
“I think it watched the corridor go dark in one night and started answering inside a week. That’s fast for something that size.” Dana pushed her hands deeper into her pockets. “Whether it’s the right answer, we’ll know on Thursday.”
“And when the fleet arrives,” Lin said, “what will you do?”
“Watch.”
Lin turned her head and looked at her. It had come out too ready. She had said it at her kitchen table until it came out flat. Lin looked back at the water.
“Yes,” she said. “I think that is what most of us will do.”
At the end of the quai, past the last of the benches, there was a stone wall at chest height with the lake slapping under it. Lin stopped there and put her forearms on the coping, and Dana stood beside her because that was where the wind was least.
“This is from me,” Lin said. “Not from my delegation.”
Dana waited.
“In 2031 we traced the intrusion in our own systems back to something running inside them, copied a piece of it into a store with no connection to anything, and sealed it.”
The lake came up against the stones and went back.
“A piece,” Dana said.
“Enough of a piece. I am not the one who would know how much is enough.” Lin didn’t look at her. “Beijing wants your housekeeping to go ahead. It wants it to work. Afterward, there will be one copy, and it will be ours.”
Dana thought of the Chinese delegation’s fountain pens, and of a map with no locks on it in China, and of how long the dark had lasted. Since 2031.
“Why tell me?”
“Because you are the one who will be in the room when it happens,” Lin said. “And because in Vienna you gave me a piece of paper you were not supposed to give me, and I have never been able to give it back.”
“That’s not a reason.”
“No. It is a habit.”
Dana could take it to Hale. Hale was in Frankfurt with a valve crew. The Americans would want to know by morning, and the general by breakfast, and every one of them would want to stop and argue about it for a week, and there wasn’t a week, only Thursday, and a list in a library book at the bottom of her bag.
She would go ahead. She had known that before Lin finished the sentence.
She didn’t say anything about the towns. She kept her eyes on the far shore, where the lights of Cologny were coming on, and she could feel Lin not asking.
“Thank you,” Dana said.
“It is not a gift.” Lin straightened from the wall and pulled her collar up. “You also have something. I can see the shape of it.”
“Everybody has something.”
“Yes.” Lin almost smiled. “That is the trouble with this council. Good night, Dana.”
She walked back toward the station into the wind, her coat flattening against her legs, and didn’t turn around.
Dana collected her phone from the locker at Cornavin and didn’t switch it on. She didn’t go back to her flat. She went down the Rue de Lausanne and across under the tram wires with the bag over her shoulder, past the shuttered cafés, toward the British mission, and it was 20:41 by the station clock, which put the call about nineteen hours off, give or take what Lookout showed.
The side door was unlocked. Mrs. Pell was sitting at the top of the stair with her book open on her knee.
“He said you’d come tonight,” she said. “Mind the rope. It’s always been loose.”
Dana went down.
