There is a hill on the way home.
He was climbing it with his rucksack on and his phone in his hand. The rucksack held his work laptop and his wallet. He kept the same things on the phone and the laptop, so he could pick up work from either. In his right trouser pocket was the second phone, the one the company issued. Keep personal and work separate — that was the rule where he worked.
Partway up the hill the street lamp seemed to brighten, and then he thought, no. What had brightened was him. He looked at his hand and it was glowing. He could see the outline of the phone through his own palm from the inside. It was not hot. It made no sound. Only the slope had gone out from under his feet.
Then the smell changed.
2
Carpet. Boiled coffee. Cigars. A chair went over, papers went up, someone drew breath and someone else could not.
"Ventilate. Open the windows. It's a German hallucinogen."
A young officer's voice. The man did not go to the windows. He could not, presumably. Beside him a white-haired man had gone down on his knees on the floor and begun to pray with his hands clasped. He himself was standing. The light was withdrawing upward from his feet, and when the brightness left his palm the phone became an ordinary phone again.
Where is this.
Then his right pocket rang. At the short electronic chime, which nobody in that room had ever heard, every eye moved at once — from the glowing figure to the glowing figure's trousers.
He took the phone out without thinking. There was no reason. He had done it for twenty years. In meetings, at funerals, people look at a phone that rings. In the middle of the Cabinet Room of the United States, something that had just come down out of the sky peered into a slab of glass in its hand.
The notification came from an app he had never seen.
ATLAS Your decisions will change this world. Choose what you wish to take with you. After that, do as you please.
He opened it. A list came up.

Twenty lines, and one more below the rule. Seventeen of the twenty were grey and only three were black, and all three of the black ones seemed to be for keeping records. He touched the lowest of them.
Admiral's Record Room Campaigns completed 0 Nations completed 0 Highest difficulty —
Zero.
He looked at the number. If there is a zero, there is a one. He stood like that for about a minute. For that minute eleven men watched in silence as a man touched something none of them could see. Nobody laughed. Nobody understood enough to laugh.
He put the phone back in his pocket, raised his head, and spoke his first words.
"Where is this?"
3
There was a long silence. It was the white-haired man on his knees who answered, looking up from the floor, forcing it out.
"Washington. The Cabinet Room."
"What is the date?"
"The twentieth. November."
"Of what year?"
The man's throat moved.
"Nineteen forty-one."
He closed his eyes. The twentieth of November, 1941. In eighteen days this country's Pacific Fleet would burn at its moorings. There are few adults anywhere who do not know that date.
I have come to the past, he thought. Steady, he told himself. I know almost everything this country is going to do in the next four years.
Then something else occurred to him. Why are we understanding each other. The white-haired man had spoken English and he had answered in English. He had not noticed at the time; noticing now, it was not the English he knew. It had come out of his mouth like a first language. He put a hand to the phone in his pocket. No reason. He just put his hand on it. No answer came from anywhere.
"The President?"
"Waiting in the next room. At once."
"May I ask your name?"
The white-haired man looked as though he did not understand the question. He answered anyway.
"President Leland G. Whitfield."
He did not move. It was not a name he knew.
"And yours?"
"Dean Mercer. Counsel to the President."
Unknown.
"And these gentlemen?"
"General Russell Vaughn, Chief of Staff. Admiral Curtis Maddox, Chief of Naval Operations."
Unknown. Unknown. Not one of them known.
He could not have recited the 1941 cabinet from memory. But he knew the President's name. Everyone in the world knows that name. And it was not here.
Something cold went down his back. This is not the past. It resembles it. It resembles it appallingly. The date, the room, the two charts on the table, what is about to happen — probably almost all of it the same. But not the same. What I know may no longer hold.
He said none of that to anyone. What he said instead was this.
"In eighteen days, on the morning of the eighth of December, a Japanese carrier force will attack Pearl Harbor."
4
It took less than a minute to convince them. He would think about that a great deal afterwards.
No proof was needed. He did not have to call a future event correctly, or perform a miracle. Eleven men had watched the light come down at the same moment. That was enough. People are cautious by nature, but people who have seen a thing with their own eyes are not. Everyone outside that room would go on doubting him for four years. The eleven inside it handed him almost everything before the day was out. The counsel who had knelt called it a sign. Only Major Ashby of intelligence kept up the hallucinogen theory to the end, and even he was rewriting the North Pacific patrol plan on his instructions the next day.
Whether they believed him was no longer the question. What to change in eighteen days, with the authority he had been given. That was all.
5
Three questions were put to him.
Land. Vaughn, the Chief of Staff, opened a map of the Pacific.
"War may begin this week. But where does the first blow fall? We cannot get adequate reinforcement to the Philippines in time. Do we hold, do we buy time, or do we prepare somewhere else entirely?"
"All three will come."
"All three."
"Hawaii, the Philippines, Malaya. The same morning."
Vaughn set his pencil down.
"What can we send to the Philippines?"
"Ships will not arrive in time. Aircraft will survive, provided they are not burned on the ground."
"Meaning what?"
"On those islands the aircraft are burned lined up on the runway, after word of the attack has already come in. The warning arrives; it does not arrive in time to matter. What is too slow is the interval between the warning and getting airborne."
He spoke for forty minutes after that, about dispersal and evacuation, about where fuel was stored and where the ground crews were quartered. Vaughn wrote all of it down.
Sea. Maddox, the Chief of Naval Operations, produced the mooring plan for Pearl Harbor.
"The fleet is concentrated here to deter Japan. Is it in fact deterring anything? Or is it a target laid out in rows?"
He was struck by how exactly right the question was.
"A target."
"Then do we sortie?"
"No."
The room stirred.
"Leave them. Leave the battleships in the harbour."
"Knowing an attack is coming, you would leave them there."
"Yes."
"Give me your reason."
He drew breath. This was the hardest ground in the eighteen days.
"If the fleet is gone from the harbour, they call the attack off. They call it off and wait for the next opportunity. I do not know when the next opportunity comes. What I know is the morning of the eighth of December."
The colour went out of Maddox's face.
"You would leave them lying there. Knowing."
"I would leave them lying there. With three changes."
He held up three fingers.
"One. The carriers must not be in the harbour that morning. Send them out. To the northeast. I will give you the reason later. Two. Air defence and readiness go onto a war footing today. Ammunition lockers unlocked. Crews standing at the anti-aircraft guns. Aircraft not parked in rows. Torpedo nets rigged. Those things alone change half of what you lose. Three. Put men on the dry docks, the fuel tanks and the repair shops. They will not strike those. They will go home without striking them. Do not prepare for the case where they are hit — prepare so that from the following morning you can work them at full capacity."
"Can you tell me for certain they will not strike them?"
"In the world I come from, they did not."
He said it plainly, in so many words.
"That does not guarantee it here. But I will take the wager."
The nation. Mercer, the President's counsel, lowered his voice.
"Public opinion is still against entering the war. If war cannot be avoided, they must fire first. Is there anything we can do besides wait?"
This was the heaviest of the three. Fire first and you forfeit your standing. Wait and men die. He could not resolve the contradiction. Historians eighty years later could not resolve it either. So he decided not to resolve it.
"Let them fire the first shot."
Mercer looked down.
"But," he went on, "they will not fire the second."

Every decision was taken that same day, and then it could not be taken back. In this country's government a decision becomes a telegram the moment it is made. Orders cross the Pacific, and where they land people begin to move. To reverse one, the fact of the reversal becomes a telegram in its turn.
Eighteen days remained. They were not days for thinking. He had nothing left to decide; the deciding was done. The eighteen days were for watching the result. Every morning when he woke he counted. Seventeen. Sixteen. Fifteen.
On the twenty-sixth of November the country sent Japan a note demanding withdrawal from China and Indochina. He was shown the draft the day before it went. He could have stopped it — he had that much authority by then.
He did not stop it.
Stopping it would have brought down the whole eighteen-day plan. That this paper be received as an ultimatum, that their carrier force sail on schedule and arrive on the morning it was meant to arrive: that was the premise of the trap he had laid.
That night, in his own room, he opened the laptop for the first time.
It powered on. The screen came up the way it always did.
The AI app was there. The one he used every day for work, still installed. The same one was on the phone.
There was an impossible single bar of signal on the company phone. His own phone stayed out of service. When he connected through the company phone, the app worked.
He understood none of the reasoning behind it. It simply reached.
The first night, what he asked about was the proximity fuze.
The answer came back. Long paragraphs and a simple diagram. The essentials of doing it with vacuum tubes. Building it to survive the acceleration of the shell. How to wake the battery. It went as far as concluding that it could be made in this period.
He went on asking. Metallurgy. Production control. How to make antibiotics. It answered all of them — carefully, with its reasoning attached, and it said so when it did not know.
Then he asked this.
On 8 December, what happens if we lie in wait at Pearl Harbor
I cannot tell you. What I know goes as far as the world you did not leave.
He sat looking at the screen for a while without moving.
At the far end of the same thin line was the other world itself.
That end was heavy. Text only. A photograph took minutes. Sometimes hours, sometimes days, went by with nothing coming back at all.
He asked the same question there, of a person.
The reply came two days later.
No such history exists. Pearl Harbor was eighty years ago. The surprise attack is regarded as successful.
He looked at those lines for a long time.
The war history of that world had not changed by a single page. Nothing he did would change it. And that world did not know what he had done.
That world, too, knew only its own history.
The thing in his hand was the same. Everything that had already been accumulated, it could answer. What happens next, neither of them knew.
You can ask about technology. But tomorrow, nobody knows.
He put the phone down and then opened the app.
There were three layers. Established history. Trends. The consequences of his own choices.
The third was blank.
The reason settled into place that same night. What he knew was the history of a world he had not entered. From the moment he put out his hand, nobody knew what came next. Not the phone. Not the other world.
At the top of the screen, the first notification was still there.
Your decisions will change this world. Choose what you wish to take with you. After that, do as you please.
He read it twice.
Who is saying this.
Choose what you wish to take with you. There had been nothing to choose. After that, do as you please. That is the way somebody speaks who is letting you.
He stopped thinking there. He had ten more days to carry it, and to sleep with it.

The eighth of December.
That morning he was in the operations room at headquarters. He stood in front of the map for seven hours.
At 0755 the first report came in.
It came.
For two hours afterwards he did nothing. There was nothing to do.
In the harbour, what he had described eighteen days earlier was happening exactly as described. The battleships were there, and they were struck. Men died. On the ships he had told them to leave lying there, men died.
But there were crews standing at the anti-aircraft guns. The ammunition lockers were unlocked. The aircraft on the fields were dispersed. The torpedo nets were rigged. The fires went out.
And the carriers were not there.
Shortly after ten the second report came. A patrol aircraft had found wakes on the surface, north-northwest.
He had known they would come from the north — that they would come by the northern Pacific route that carries no shipping. Any child eighty years later knows it. But you cannot explain knowing it. So eighteen days earlier he had given one instruction and no more: widen the patrol fan to the north.
At eleven, Maddox looked at him.
"Adviser. The second shot."
"Yes."
"You said you would not let them fire it."
"I did."
Northeast of the islands lay three carriers, in the position he had made them take eighteen days before without giving a reason. Task Force One. Rear Admiral Randall commanding — a man the navy said believed in aircraft.
What happened in the northern Pacific from that afternoon into the next day became the first chapter of this country's naval history. He did not direct that battle. Maddox gave the orders and Randall carried them out. What he had done was say three things, eighteen days earlier.
By evening the Japanese carrier force could no longer go home in the shape it had arrived in.
That night President Whitfield sent for him.
"We shall have to settle on a title for you."
The President laughed with a tired face.
"Special Adviser, let us say. One can hardly write God into a federal document."
8
The following week he made another wager.
There was a convoy running south through the South China Sea, carrying troops for Malaya. In the world he came from, that convoy completed its landing unmolested.
"Can we hit it?"
"War is declared. We may fire," Vaughn said. "But it is far. We have not enough aircraft with the range."
"How many aircraft are left in the Philippines?"
Vaughn raised his head. The aircraft that had not been burned were there. The forty minutes of eighteen days ago came back to him at that moment.
Less than half the convoy was reached. Even so the landing was delayed, and by as much as it was delayed the troops that did get ashore had to wait for supply, and while they waited the rainy season arrived. History had begun to change shape by the width of his finger.

The three years that followed are a story about factories. He never once went to the front. What he did was ask, digest, and hand over.
The proximity fuze went to sea in the autumn of 1942, nearly a year earlier than in the world he came from. The hit rate of anti-aircraft fire changed, and it took the other side six months to notice the change and alter how they fought.
The idea of gathering radar, radio and the plotting table into a single room aboard ship — he drew the diagram himself and handed it over. This is not technology, he said, it is where you put the furniture. Where they put the furniture changed who won night actions.
For anti-submarine work he handed over the hunter's organisation. Escorts are not sent out to protect; they are sent out to sink. He took that idea wholesale from a textbook eighty years in the future.
For production he handed over the use of statistics. Sampling inspection and the process control chart. It looks unrelated to the war, he explained, but it means that identical shells from the same factory fly identically. Four months later the dud rate had halved.
And he handed over medicine. Nobody in the service thought much of it. He considers it the best thing he did in four years.
Throughout, the second layer of the app — the band of trends — kept widening. Every time he did something, its upper and lower edges drew further apart. The projection of Japanese production, the projection of his own side's losses: what had been a thin line was now a broad band, hollow down the middle. The more he put his hand in, the less could be seen ahead.
10
In the summer of 1943 Ashby came to him, a colonel by then. The intelligence officer who had shouted about hallucinogens.
"Adviser. Something odd has come up."
Photographs of components from a captured aircraft.
"These came out of one of theirs. That country should not be able to make this, not at this date."
He looked at the photographs. Then he was shown another sheet: a fragment of decrypt.
"And this may be my own error."
In the fragment there was one word that made no sense. He knew the word. It was a word that did not yet exist in this period.
"Colonel Ashby."
"Sir."
"In the last six months — have their communications stopped making mistakes?"
Ashby's face changed.
"How do you know that?"
He did not answer.
That night, in his room, he did not move for a long time. Fight quietly and it comes late. Fight spectacularly and it comes early. He had fought spectacularly. He had put the proximity fuze out a year ahead, ambushed a carrier force, broken up a convoy, changed the shape of history. The other side had been watching those traces. He had called them himself.
For the first time he felt he could see the logic of the arrangement. How large he moves is something he decides. And when the other side arrives is decided by how he decides it. Not a curse. An instrument with a scale on it. This time he had used it without reading the scale. If there is a next time — and, catching himself thinking that, he laughed a little. If there is a next time, indeed.
11
The war ended in the autumn of 1944, nearly a year earlier than in the world he came from.
It ended in a way he had not expected. There was no great decisive battle. Their oil ran out, their ships ran out, the men to fly their aircraft ran out. The margin he had made in eighteen days had become, over three years, that kind of margin. That was all.
The terms were a little softer than in the world he came from. He took no part in those negotiations.
And in the summer of 1945, it was completed.
The war was over. There was no longer anyone to use it on. It was completed regardless — in the month he knew, in the place he knew, the thing he knew.
He read the news in a newspaper.
He did not move.
There was a great deal he had moved. Carriers saved at Pearl Harbor. A carrier force sunk in the northern sea. Aircraft in the Philippines not burned. A fuze at sea a year early. A war ended a year early. History had indeed changed shape by the width of his finger.
But that summer had not moved by a single day.
He could not yet put into words what that meant.
12
In the autumn of 1945 the victory celebrations, held late, ran for three days.
On the third night he left the hall. It was a city he had lived in for four years. Nobody knew his real name; in four years he had never once given it. He meant to go back to the offices and clear the paperwork that had piled up during the celebrations. The title of Special Adviser comes with a surprising amount of clerical work.
He was walking the corridor of the offices when his right pocket rang. That sound, for the first time in four years. He stopped and took out the phone.
ATLAS Operations in this world are complete. Your decisions have changed this world. Choose what you wish to take to the next one.
He read it. The next world.
The same words as the first notification, with only the tense moved into the past. And "after that, do as you please" was gone. Because he had already done as he pleased, he thought — and then was slightly startled at how cold his own thought was.
He opened the app. Three of the twenty lines had turned black.
Elite Battleship Squadron Unlocked War Economy Unlocked Campaign Chronicle Unlocked …… Admiral's Record Room Campaigns completed 1 Nations completed 1 ―――――――――――――――― Next Theatre Modern Fleet Requirements not met Remain in this world Requirements not met
The zero had become a one.
He opened the line for the Elite Battleship Squadron. When you next begin, it said, you may bring this formation with you. When you next begin. The app had known from the outset that there would be a next.
He looked below the rule. There were two lines.
Remain in this world. Requirements not met.
He put his finger on it. Nothing happened. So one cannot remain. He stood a while in the corridor of a city he had lived in for four years.
Then he closed the screen. He chose nothing. Whatever could be chosen, it said, would come with him whether he chose it or not. Everything except remaining.
After he closed it, the light came up around his feet.
"Ah," he said.
The same brightness, after four years.
The smell changed. Not coffee, not cigars: tobacco tar, damp paper, oiled paper. Under his soles, cold stone.
A chair going over. Papers going up. Someone drawing breath.
And his right pocket rang.
He looked slowly around him. A conference table in green baize. Seven ashtrays. On the wall chart a red pencil line ran from the South China Sea down to the Malay Peninsula. The date on the papers on the table was the twentieth of November, Shōwa 16. Fourteen men were looking at him. One of them, an elderly admiral, bowed deeply.
"We take this to be the advent of a god of war."
The next world was Japan.
