The call came on Wednesday morning. I was still in bed, still nursing the hangover from the previous night, when the phone rang. I let it ring twice before I picked it up. I do not like answering phones. Phones are promises of conversation, and I have never been good at conversation.

This one was different. A man on the other end said his name was Richard Chen, and his sister, Dr. Margaret Chen, had been missing for three days. He offered me five thousand dollars and six months in a Manhattan apartment, forty dollars a week, if I could find her personal notebook.

What kind of scientist keeps a notebook instead of putting everything on a computer? I asked.

The kind who knows people hack computers, he said. The notebook is in her apartment. Find it. That is all.

I could have said no. I have said no to harder questions. But five thousand dollars is five thousand dollars, and the apartment was an added bonus I did not refuse.

Margaret Chen's apartment was in Brooklyn, a fourth-floor walk-up with peeling paint and a landlord who only showed up when rent was late. The door was unlocked. Inside, the apartment was clean in the way of someone who had left in a hurry but not in panic. No overturned chairs. No broken glass. Just a coffee cup on the kitchen table with a skin of mold on top.

I started looking under mattresses. Not my idea of efficient investigation, but the client had said notebook, and notebooks in scientist apartments tend to be where scientists hide things. Mattresses. Baseboards. Behind bookshelves.

I found it under Margaret Chen's bed, wrapped in a dish towel. A small black sketchbook, the kind students use for homework. I opened it and flipped through.

No formulas. No data. Just drawings of the sun.

Dozens of them. Maybe hundreds. From different angles, different lighting, different conditions. And at the top of each page, a date. The earliest drawing was labeled two months ago. The sun looked normal. Or as normal as a ball of nuclear fire burning forty thousand miles away can look.

But the drawings progressed. Subtly at first. A slight dimming here, a color shift there. By the last drawing, dated two weeks before she disappeared, the sun looked wrong. Smaller. Darker. And beneath it, in neat handwriting, were four words:

72 hours. Maybe less.

I sat on her floor and stared at those words for a long time. Then I wrapped the notebook back in the towel and put it back under the mattress. Not my problem. Not my problem at all.

But I needed the money.

The first person I went to see was Frank O Malley. Everyone called him Fingers. He ran a打字机 repair shop down in lower Manhattan that was a front for whatever information trade happened behind those walls. Fingers had been an FBI informant in the fifties, which meant he knew things the FBI wanted forgotten. He had also survived that long, which meant he knew how to keep other people's secrets.

The bell above his door jingled when I entered. The shop smelled of machine oil and old paper. Fingers looked up from a broken Underwood and saw me. His face did not change, but something in his eyes did. Something like recognition mixed with fear.

I am looking into a missing person, I told him. A scientist. Dr. Margaret Chen.

His pen stopped moving. He set it down carefully, like he might need it to defend himself.

You should not be looking into anything, Callahan.

Her brother hired me. Five thousand dollars.

That is a lot of money for a missing persons case.

It is more than a lot for a case that goes nowhere, I said.

Fingers stood up and walked to the back room. I heard him lock a door. When he came back, he was holding a cigarette he had not lit.

There was a program. During the war, they called it Hermes. After the war, they just kept doing it. Deals with people who see things in the sky that other people should not see. Your sister was one of those people.

What did she see?

Fingers took a breath. Hermes was looking for someone. A woman in a gray coat. Asian. She asked me about a physicist at Brooklyn College. I told her I did not know her. Three days later, she disappeared.

How does the sun relate to any of this?

Fingers shrugged. You figure that out, you are smarter than both of us.

I left Fingers with a twenty-dollar bill he refused and a headache I did not ask for.

The second night, I found something in Margaret's apartment that Fingers had not mentioned. A folded newspaper from her trash, or what was left of it. The New York Times, March 16th. The headline on the front page was about the Senate rejecting a space defense budget. On the blank margin, in Margaret's handwriting, was a sentence fragment:

They will not believe. So we must

The rest had been torn away. Carefully. With scissors, not anger.

The third night, I followed a man in a gray coat through the streets of Manhattan. He moved like someone who knew how to be invisible, but I have spent twenty years finding people who do not want to be found. He ended up in Central Park, near a bench that faces the reservoir, and stood behind a rock the way people do in movies when they are supposed to be waiting for someone.

He was not waiting for someone. He was waiting for something to be left.

I watched from across the path for twenty minutes. He pulled a small metal box from inside his jacket, set it on the ground behind the rock, and walked away without looking back.

I went over when he was gone. The box was locked, but locks are not hard for someone who has picked locks since the Nixon administration. Inside, I found the same newspaper. The Times, March 16th. But this one was clean. No torn edges. No handwriting.

Except when I held it up to the streetlight, I could see pressure marks. Words written on paper that had been placed on top of this newspaper. I had done this once before, in the academy before they threw me out for asking too many questions.

I went home and rubbed pencil graphite over the surface. The words appeared:

They will not believe. So we must tell them ourselves. And if they shoot the messenger

The rest faded into illegibility.

The fourth night was the seventy-second hour. I knew this because I had been counting. Margaret had disappeared on Wednesday afternoon. It was now Saturday morning, just after midnight.

I found her beneath the Brooklyn Bridge. Not surprising, really. It is where broken things go in New York. The bridge has been swallowing secrets since 1907.

She was sitting against one of the concrete pillars, wearing a white bathrobe. In March. In New York. At midnight. Her face was turned upward, toward the sky. And she was smiling.

Dead people are not supposed to look peaceful. Margaret Chen looked peaceful.

Next to her on the ground was a small transistor radio. The dial was between stations, sitting in the white noise. I picked it up and held it to my ear.

It was not static. Not exactly. It was a low, sustained sound. Like something massive moving above the atmosphere. Something enormous and silent until it was not.

I put the radio down and looked up. The sky was the normal color of light pollution, a yellowish gray that hides the stars. But for a moment, just a moment, I thought I saw something. A brightness. Not the sun, not yet. But moving toward it.

I took the notebook from my coat pocket and walked home.

Richard Chen never paid me. When I went to his office in midtown Manhattan, the receptionist said she had never heard of a Dr. Richard Chen. When I went back to my bachelor apartment in Queens, someone had been through everything. Not ransacked. Gone through. Selective. The notebook was gone.

But I had copied the last page. Or at least the part I could read.

I am sitting in a bar in Queens now. The television above the counter is showing news. A reporter is talking about unusual brightness in the eastern sky. Millions of people are looking up. The bartender said people have been taking early shifts, just standing outside and staring.

I drink my whiskey. It tastes like everything else in this city, which is to say like it was made from something that once grew somewhere under open sky.

In my pocket is the notebook. The last page reads:

I am sorry, Jack.

She knew. She knew I would find it. She knew I would read it. She knew I would sit here tonight and look at the sky and understand that I am, as of this exact moment, the last person on Earth who knows what is coming.

The bar fills with people leaving work. They look at me the way New Yorkers look at anyone who is not looking at them. Curious and indifferent at the same time.

I finish my drink and stand up. The bartender does not ask how much I owe. He sees my face. Everyone in New York has learned to read faces.

Outside, the air is cold. The sky is the color of dirty wool. But if I look east, just before the sun comes up, I think I can see it. A brightness that is not the sun.

Not yet.

But it will be.
