On the first Tuesday of September 2005, Sameer Al-Jamil stood in his driveway on Maple Street, a garden hose in his right hand, watching Mrs. Patricia Holloway from three houses down approach him with the kind of deliberate casualness that he had learned, over the preceding weeks, to recognize as the shape of something being lowered into position. She carried a Tupperware container, the translucent lid fogged with condensation, and her smile was the same smile she had worn when she brought him a zucchini bread the week after his wife Fatima died, four years ago, but there was now a quality to it that he could not name, like a photograph that had been left in the sun too long and had gone thin at the edges.

Good morning, Dr. Al-Jamil, she said, stopping at the edge of his driveway, her sneakers on the concrete. She did not step onto the grass. I wanted you to have this. My daughter made too much pasta salad for the Labor Day picnic.

He thanked her and took the container. The exchange lasted perhaps forty seconds. She asked about his classes at the university. He said they were going well. She nodded, her eyes traveling from his face to the hose in his hand to the front door of his house and back to his face, and then she said, You know, the homeowners association is having a meeting Thursday night. About the new speed bumps. You should come.

He said he would try. He had said he would try to the last three meetings, too. She smiled again and walked back the way she had come, past the McCormicks mailbox, past the For Sale sign that had appeared on the Russells lawn three weeks ago, past the place where the pavement met the curb and the concrete was cracking just a little, like a fault line nobody talked about.

He went inside and set the pasta salad on the kitchen counter beside the other Tupperware containers, four of them now, all from neighbors, all delivered in the last two weeks with the same careful choreography. Banana bread from the Millers. A casserole from the Garcias. A jar of pickles from old Mr. Hendricks, who had not spoken to him above a murmur since the war in Iraq began. The food was good. The food was always good. The food was a message written in a language he understood perfectly, because he had been trained to read it: We remember that you are one of us. We are reminding ourselves that you are one of us. We are practicing.

He taught Introduction to Middle Eastern Political Thought on Tuesdays and Thursdays in a lecture hall that had been renovated in 1988 and not touched since. The room smelled of floor wax and old paper and the particular staleness that accumulates when windows have been sealed for reasons of energy efficiency. Twenty-three students sat before him, arrayed in the loose amphitheater of beige plastic chairs, and he stood at the lectern with his notes arranged in a folder that Fatima had bought him for his forty-second birthday, and he talked about Al-Farabi and the concept of the virtuous city.

A girl in the third row raised her hand. She was blonde and wore a cross on a thin chain around her neck, and he had learned her name on the first day but had since forgotten it, which was unlike him. Dr. Al-Jamil, she said. How do you reconcile Al-Farabis ideas about the ruler being both philosopher and prophet with the fact that, you know, the Prophet Muhammad wasnt a philosopher? I mean, he was a merchant. Isnt that a contradiction?

He answered the question. He answered it carefully, with citations, with the same precision he had used for fifteen years, and he thought the answer was adequate, but something in her eyes — a tightening, a slight tilt of the chin — told him that she had not been asking about Al-Farabi. She had been asking about something else, something that sat beneath the question like a second text, and she was disappointed that he had not addressed it.

After class, the department chair, a man named Gerald Towne who wore bow ties and had the soft, pink hands of someone who had never changed a tire, asked Sameer to step into his office. The office was small and windowless, lined with books that looked as though they had been purchased by the yard. Gerald closed the door behind them and gestured to a chair, and then he sat behind his desk and folded his hands and said, Sameer, I want to be frank with you.

Of course, Sameer said.

Ive had a few concerned calls, Gerald said. From parents. You know how it is. The world being what it is. Some of them are worried about the content of your syllabus. Theyve heard things.

What things?

Gerald sighed, a performance of reluctance. That youre assigning readings that are, well, sympathetic to certain ideologies. That youre using the word jihad without sufficient context, or with context that some might find, ah, mitigating. I told them you were an excellent scholar. I told them you had tenure. But I also told them I would talk to you.

Sameer said nothing. He had been at this university for twelve years. He had published two books. He had won a teaching award. He had sat beside Gerald at faculty dinners and listened to Gerald complain about his prostate. And now Gerald would not look him in the eye.

Im not asking you to change anything, Gerald said. Im just asking you to be mindful. To be aware of the temperature of the room. I think you understand what I mean.

Sameer understood. He had understood for a long time.

That evening, he walked to the mailbox at the end of his driveway and found a flyer tucked between the gas bill and a catalog from LL Bean. The flyer was printed on good paper, cream-colored, and it read: NEIGHBORHOOD WATCH MEETING — THURSDAY 7:30 PM — COMMUNITY CENTER — ALL RESIDENTS ENCOURAGED TO ATTEND. There was no mention of what would be discussed. There did not need to be.

He stood at the end of the driveway, the flyer in his hand, and looked up and down Maple Street. The street was quiet. The sun was low, the light golden and long. The Russells house was dark, the For Sale sign a white rectangle against the dying grass. Mrs. Holloway was watering her petunias, her back to him. Mr. Hendricks was bringing his trash cans in from the curb. Nobody was looking at him, and everybody was aware of where he was standing and for how long.

On Thursday, he did not go to the meeting. He told himself that he had papers to grade, that the meeting was about speed bumps, that his presence would only make things worse. But the truth was simpler and harder: he did not go because he was tired. He was tired of being the subject of conversations that he was not invited to join. He was tired of performing normalcy while everyone around him performed the careful, polite rituals of exclusion. He was tired of the food.

He graded papers until eleven oclock. He watched the news. The news was about the war, about the president, about terror alerts coded by color. He turned off the television and sat in the dark living room, and he thought about Fatima, who had loved this house, who had planted the rose bushes that were now overgrown and wild. She had loved the neighborhood, too. She had believed in neighbors. She had been the one who brought cookies to the Welcome Wagon when they first moved in, twelve years ago, a young couple with a baby on the way, a daughter they would name Layla, who was now eleven and sleeping in the room at the end of the hall.

He heard a car door close outside. He watched from behind the curtain as a sedan pulled away. He did not know who had been in it or where they had been. He went to bed.

The next morning, he found an envelope taped to his front door. Inside was a handwritten note on stationery that smelled faintly of lavender. The handwriting was rounded and careful, a schoolteachers hand.

Dear Dr. Al-Jamil,

I hope this note finds you well. I am writing on behalf of several families on the block to express our concern about the flags. I understand that you have the right to express your beliefs, and I respect that. But some of the children have been asking questions, and we are not sure how to answer them. The crescent flag in your window is very prominent, and during these times, it can be... unsettling. We would be grateful if you would consider taking it down, just for a little while, until things calm down. We all want what is best for the neighborhood.

With warm regards, A Concerned Neighbor

He read the note three times. Then he folded it carefully and put it in the drawer of his bedside table, beside Fatimas prayer beads, which he had not touched since she died. He walked to the living room and looked at the flag. It was small, no larger than a sheet of printer paper, hanging in the corner of the bay window where the morning light caught it. Fatima had hung it there the week they moved in. It had been there for twelve years. It had never bothered anyone before.

He left it where it was.

That afternoon, he took Layla to the library. She was reading at a level two grades above her age, and the librarian, a cheerful woman named Denise who had always had a kind word for them, was coolly professional today, her smile not quite reaching her eyes. She helped Layla find a book about space exploration and did not ask about Sameers research or remark on the weather as she usually did. The transaction was efficient and blank.

In the parking lot, Layla said, Daddy, why doesnt Mrs. Holloway wave anymore?

She waved this morning, he said.

No, she said. She waved at you. She didnt wave at me.

He looked at his daughter, at her dark hair and her brown eyes and the face that was her mothers face, and he felt something in his chest close like a fist. She waved, he said. You must have missed it.

Layla looked at him for a long moment, and then she said, Okay, and got into the car. She did not mention it again, but she did not have to. She was eleven years old, and she had already learned to read the language of the neighborhood better than he had.

October came, and the leaves turned, and the neighborhood watch meetings continued. The flyers kept appearing in his mailbox. The food stopped coming. The conversations that stopped when he entered the grocery store aisle stopped with less urgency now, as if the people involved had decided that he was no longer worth the effort of pretending. He was assigned to teach the 8 AM section of Introduction to Middle Eastern Political Thought instead of the 11 AM section, and when he asked Gerald about it, Gerald said it was a scheduling issue, and they both knew it was not.

He began to notice small absences. The newspaper was sometimes missing from his driveway in the morning, tossed instead onto the grass, where the dew soaked it through. A package that he had ordered — a new translation of Ibn Rushd — was left not on his porch but at the bottom of the steps, where anyone walking by could have taken it. The trash collectors, who had always returned his bin neatly to the side of the garage, began leaving it in the middle of the driveway, forcing him to stop his car and move it before he could pull in.

None of these things was, by itself, anything. They were not vandalism. They were not threats. They were not crimes. They were the smallest possible signals, each one calibrated to be deniable, each one saying exactly what it meant without saying anything that could be quoted. They were the social immune system doing what it did best: recognizing what did not belong and applying gentle, persistent pressure until it was expelled.

He did not fight it. He did not know how to fight it, because there was no target. You could not argue with a missing newspaper. You could not complain about a mailbox flyer. You could not call the police about a shift in the quality of a smile. The system was not cruel. It was not even unkind. It was simply—efficient. It found the foreign body and it surrounded it, layer by layer, cell by cell, until the foreign body either dissolved or left.

He started grading papers at the university library instead of at home. He started grocery shopping at a store on the other side of town, where nobody knew him. He stopped walking in the evenings, because the looks that the new neighbors — the ones who had moved into the Russells house, a young couple with a German shepherd and a flag decal on their SUV — gave him when he passed were not hostile, exactly, but they were attentive in a way that felt like surveillance.

In November, Gerald called him into his office again. The windowless room seemed smaller than it had before. Gerald did not ask him to sit.

Sameer, Gerald said, I have to be straight with you. Enrollment in your 8 AM section has dropped from twenty-three to nine. Students are transferring out. Theyre citing, ah, discomfort. The administration is asking questions. Ive done what I can, but —

Im not changing my syllabus, Sameer said.

Gerald blinked. I didnt ask you to.

You didnt have to.

There was a silence. Gerald looked at his hands, at his soft pink hands, and then he looked up and said, I think you should consider taking a leave of absence. For the spring semester. Paid. Use it to finish your book. Let things cool down.

And if I dont?

Then I cant guarantee what happens next.

Sameer looked at Gerald for a long time. He thought about Fatima, who had loved this town, who had believed that if you were good and kind and patient, the world would eventually be good and kind and patient in return. He thought about Layla, who was learning the wrong lessons about the world and learning them far too young. He thought about the flag in the window and the Tupperware containers in the kitchen and the flyers that kept coming, week after week, like the pulsing of a slow, steady heartbeat.

He took the leave of absence.

He did not take down the flag. He did not move. He did not leave Maple Street. But the leave of absence was what the system had been waiting for, because it meant that he no longer had a public role, no longer had the protection of institutional affiliation, no longer had a reason to be here that could be explained to anyone who asked. He became, officially, the man who used to be a professor, the man who was home during the day, the man whose daughter went to the local elementary school and whose wife was dead and whose flag hung in the window.

The flyers stopped coming. The newspaper resumed its place on the driveway. The trash bin was returned to the side of the garage. The system had achieved equilibrium. The foreign body had been isolated and neutralized without surgery, without confrontation, without anyone ever having to admit that any of it had happened. The neighborhood was at peace.

On the last day of the year, Sameer stood at the living room window, looking out at Maple Street under a thin layer of snow. The street was beautiful in the snow, quiet and clean, the houses glowing with Christmas lights that the families had not yet taken down. Mrs. Holloway was shoveling her walk. Mr. Hendricks was scattering salt on his driveway. A child was building a snowman on a lawn that had once belonged to the Russells.

He thought about calling the university to tell Gerald that he would not be coming back in the fall. He thought about looking at apartments in Chicago, where his brother lived, where nobody knew his face or his name or the shape of his beliefs. He thought about taking down the flag.

He did none of these things. He stood at the window and watched the neighborhood go about its business, and he understood, with a clarity that felt almost peaceful, that he had not been driven out. He had been contained. He had been placed in a space where he could do no harm, where his ideas could not spread, where his presence could be acknowledged without being accepted. He had been managed.

This was not the war he had prepared for. There were no bombs, no checkpoints, no interrogations. There were only Tupperware containers and scheduling changes and notes on lavender-scented stationery. There was only the slow, patient, inexorable pressure of a community deciding, without ever having to say it aloud, that it would be better off without him.

And the terrible thing — the thing that he would never say aloud, not to Layla, not to his brother, not to himself in the dark of the night — was that he was not sure they were wrong.
