The motel room smelled like mildew and someone else's bad decisions. Mark Whitman sat on the edge of the bed with a paper cup of tap water and watched the rain hit the window. The air conditioner was broken. It had been broken for three weeks and the office at the front desk had not returned his calls.

He was thirty-one years old and he had been unemployed for eleven months. He had been divorced for eight. He had a four-year-old daughter who lived with her mother three hours away and whom he saw every other weekend if the ex-wife remembered to tell him about the visit two days in advance.

He was wearing the same clothes he had worn yesterday and the day before. A pair of jeans that were starting to thin at the knees and a button-down shirt that had been white once but was now the colour of weak tea. He had one suit for job interviews, but he had worn it so many times that the elbows were shiny and the collar was stretched.

He was going to the employment agency tomorrow. He had decided this the night before, which meant he had probably decided it the night before that too. Decisions were cheap. Getting there was expensive. The bus fare alone was four dollars, and Mark had approximately twelve dollars in his wallet.

The man found him at the agency.

Mark was sitting on a plastic chair in a room full of other plastic chairs, reading the want ads in a newspaper that was two days old, when the man sat down next to him. He was dressed well—suit, tie, polished shoes—and he had the kind of face that made you trust him before he opened his mouth.

"Mark Whitman?" the man said.

"That's me."

"I'm Greg. I think we're brothers."

Mark looked at him. Really looked at him. The man had his nose. His jawline, if you squinted. His hands, even. Same long fingers, same slightly crooked pinky on the left hand.

"I don't have a brother," Mark said.

"Not that kind of brother. Twin. We were in the foster system together. I was placed with the Whitmans on Elm Street. You were placed two streets over, with the Millers. We used to meet at the park on Saturdays. Don't you remember?"

Mark didn't remember. But the man was sitting next to him, and he was saying things with a certainty that felt like truth, and Mark was tired, and being tired made everything feel heavier than it was.

"Okay," Mark said. "Okay."

Greg smiled. It was a warm smile, the kind that made you feel like everything was going to be all right. Mark had not felt like everything was going to be all right in a very long time.

"Come on," Greg said. "Let's get you something to eat."

They went to a diner three blocks from the agency. Greg ordered for both of them—eggs, toast, coffee, orange juice—and when the food arrived, he pushed Mark's plate closer to him and told him to eat.

"You look like you haven't eaten in a week."

"I haven't," Mark said, and it was true, but he didn't say more. He just ate.

After breakfast, Greg took him shopping. He bought Mark a new shirt—white, crisp, the kind of shirt that made you stand a little straighter. He bought him a tie. He bought him a belt. He bought him shoes that didn't have cracks in the soles.

"You can't interview in that shirt," Greg said, holding up Mark's tea-coloured button-down with an expression of genuine horror. "You can't interview in anything you own, Mark. Not unless you want them to see you as a man who has given up."

"I haven't given up."

"Yes, you have. But that's okay. You can give up and then start again. That's what brothers are for. We're the people who help you start again."

Mark let Greg pay for everything. He told himself it was temporary—just this once, just until he got a job, just until he could pay Greg back. But he knew that was a lie. He would not pay Greg back. He would take the shirt and the tie and the shoes and he would wear them to his interview and he would pretend that he had always owned them.

That was fine. That was what he did. He pretended.

The interview was at a warehouse on the industrial side of town. Mark wore the new shirt and the new tie and the new shoes, and he stood in front of the mirror in his motel bathroom and for one moment—just one moment—he saw someone who looked like he had his life together.

Then the moment passed and he was back in the motel, and the mirror showed him a man in clothes that didn't quite fit, standing in a room that smelled like mildew, with a hairline that was receding and a stomach that had gotten soft from too much sitting and not enough doing.

He went to the interview. He answered the questions. He said the right things. He got the job.

It was a warehouse position—picking and packing, standing on his feet for eight hours, lifting boxes that were heavier than anything he had lifted in years. But it was a job. It was money. It was something.

He told Greg about it that evening, over pizza at a place Greg had recommended. Greg ordered extra cheese and told Mark he deserved it.

"You earned it," Greg said. "You showed up. You wore the shirt. You answered the questions. That's more than most people do."

Mark ate the pizza. It was good. He had not realized how hungry he was until the first slice was gone.

Over the next few weeks, Greg became a part of Mark's life the way rain becomes part of a city—pervasive, unavoidable, changing everything without anyone quite knowing when it started. Greg showed up at the apartment Mark was renting from his ex-wife's sister. Greg brought Mark coffee in the morning and asked him how his interview went. Greg told him what to say in interviews and what not to say and how to shake hands and how to make eye contact.

"You're a good man, Mark," Greg told him. "But good isn't enough. You have to be the kind of good that other people can see."

Mark started practicing in the mirror. Handshake. Eye contact. Smile that didn't look like he was trying too hard.

It worked. He got another job—a better job, at a distribution centre two towns over, with health insurance and a four-week vacation and a path to promotion. He told his ex-wife, and for the first time in eight months, she sounded almost pleased to hear from him.

" You're doing well," she said. "I'm glad."

Glad. The word sat in Mark's chest like a warm stone.

But there were small things. Things he noticed but didn't want to name.

Greg never ordered food when they ate together. He would sit across from Mark at a restaurant and talk and talk and talk, and when the check came, Mark would pay, and Greg would say thank you with that warm smile and then say, "Next time is on me," and there would never be a next time.

Greg never looked at himself in mirrors. When they passed a shop window, he angled his body away. When they were in a room with a mirror, he stood with his back to it. Mark noticed this but didn't say anything. Some things you notice and don't name, because naming them makes them real, and some things are easier left unnamed.

And then there was the daughter. Mark's daughter, Lily. Four years old, with her mother's eyes and his stubborn chin. Greg had never mentioned her. Not once. When Mark talked about her—which he did, more than he had done in years—Greg listened and nodded and said things like "That's wonderful, Mark" and "You're a good father," but he never asked to meet her. Never asked to see a picture. Never asked a single question about the child who was, by any definition, Mark's most important responsibility.

Mark noticed all of this. He filed it away in the part of his brain that filed things away—the part that had learned, over thirty-one years, that noticing was not the same as acting.

The end came on a Tuesday in March. Mark was at the distribution centre, lifting boxes and counting packages and standing on his feet for eight hours, when his phone rang. It was Greg.

"Mark," Greg said. "I need your help with something."

"Sure. What is it?"

"I need you to look at something. A business card. I think I might have dropped it somewhere, and I want to make sure it's mine."

Mark was at work. He didn't have time for this. But he was at work, and the work was repetitive and his mind was elsewhere, and so he said: "Okay. Send it to me."

Greg sent a photo. It was a business card. Greg Whitman. Senior Consultant. Career Advisory Services.

Mark stared at the card. He knew the name. He had seen it before, but he didn't know where. He put the phone down and lifted a box and set it on the conveyor belt and tried to think.

That evening, after work, he called the number on the card. It rang twice.

"Good evening, Career Advisory Services. This is Sandra speaking. How can I help you?"

"I'm calling about a Greg Whitman. Is he—does he work for you?"

There was a pause. Mark could hear typing in the background, the clack-clack-clack of someone looking for information.

"Let me check," Sandra said. Another pause. "I'm sorry, but I don't believe we have anyone by that name on our staff. Are you sure you have the right company?"

Mark felt something cold move through his chest. "Are you sure?"

"Let me check again." More typing. More silence. "I'm certain. We don't have a Greg Whitman."

Mark hung up the phone. He sat on the edge of his bed and stared at the wall and tried to understand what he was looking at.

Greg Whitman did not exist.

Or rather, Greg Whitman existed, but not as the man who had been appearing in Mark's life for the past three months. The man who had been appearing was wearing Greg Whitman's name like a coat—trying it on, seeing how it fit, deciding whether to keep it.

Mark thought about the restaurant where Greg never ordered food. The mirrors he avoided. The daughter he never asked to meet. The job he helped him get. The shirt. The tie. The shoes.

He thought about the way Greg had looked at him in the employment agency, sitting next to him on that plastic chair, saying we're brothers with a voice so warm and certain that Mark had wanted to believe him.

He thought about the fact that he had wanted to believe.

The next morning, Mark woke up and made coffee and ate toast and went to work. He lifted boxes and counted packages and stood on his feet for eight hours. He came home. He ate dinner. He watched television. He went to bed.

He did not call Greg. He did not look for Greg. He did not ask anyone if they had seen him.

He went to work the next day and the day after that and the day after that. He came home. He ate. He watched television. He went to bed.

One evening, his ex-wife called. "Lily asked about her uncle today," she said.

Mark was in the kitchen, making spaghetti. The water was boiling. The garlic was sizzling in the pan. "What did she say?"

"She said, 'Mom, when am I going to meet my uncle Greg?' And I didn't know what to say."

Mark stirred the sauce. He stirred it slowly, methodically, the way he had learned to stir things when stirring was the only thing he had control over.

"Tell her," Mark said, "that her uncle Greg is a very busy man. But that he loves her very much."

His ex-wife was quiet for a moment. Then she said: "Mark, is everything okay?"

"Yes," Mark said. "Everything's fine."

He hung up and finished the spaghetti and ate it at the kitchen table and washed the dishes and went to bed.

In the morning, he woke up and made coffee and ate toast and went to work. And on the way to the bus stop, he passed a shop window, and for the first time in three months, he looked at his reflection.

He saw a man in a thinning shirt with shiny elbows. A man with a receding hairline and a soft stomach and a face that looked like it had learned to accept things it did not like.

He saw a man who had been helped by a stranger and had called it brotherhood.

He saw a man who had chosen not to know.

He kept walking.

At the distribution centre, his supervisor told him he was doing good work. Good work. The words sat in Mark's chest like a warm stone.

After work, he went home and made spaghetti and ate it at the kitchen table and washed the dishes and went to bed.

In the morning, his daughter would ask about her uncle Greg, and he would say that her uncle Greg was a busy man who loved her very much, and she would believe him, because children believe what their fathers tell them, and that was the way of the world.

And Mark would go to work, and he would lift boxes, and he would count packages, and he would stand on his feet for eight hours, and he would come home and eat and watch television and go to bed, and he would do all of these things with the quiet, unremarkable dignity of a man who had learned that sometimes the most honest thing you can do is not to know.
