“You seem unashamed to,” Mustafa said. Then he felt Fadwa’s hand on his wrist and knew he had been overruled.

The doctor knew it too: “Let me get someone to take your financials.”

While they waited to see whether the clinic would deliver more than hope in exchange for their savings, Mustafa and Fadwa received other therapeutic suggestions from family and friends: folk remedies, charms, foods to eat and foods to avoid. Mustafa’s uncle Tamir, with the authority granted him by the eight children he’d sired, said that getting a woman pregnant was mostly a matter of proper positioning during the sex act.

And there were religious therapies, too. In addition to her regular attendance at mosque, Fadwa began making weekly pilgrimages to an Armenian church dedicated to Umm Isa, the mother of the prophet Jesus. Mary, revered by Muslims as well as Christians, was believed by some to be able to intervene on behalf of the faithful; pregnancy issues were, for obvious reasons, one of her specialties. A few of Mustafa’s Sunni cousins grumbled that this was idolatry, but Mustafa was more concerned that, like everything else they tried, it would prove ineffective.

“Fadwa,” he said one evening, as she prepared for her visit to Umm Isa’s house, “you know I’ll never stop praying for you to be able to have a child, but if . . . if it doesn’t happen, will we—”

She looked at him as if he were an idolater—or a blasphemer. “How dare you say that! How dare you say that! God can do anything!”

“God can do anything,” Mustafa agreed. “He can say no. If He does—”

But Fadwa didn’t want to hear If He does.

Mustafa went to see his father. Alone among the relatives, Abu Mustafa had refrained from volunteering advice so far, but now Mustafa asked him the question that Fadwa refused to consider: “What if nothing works? What if we simply can’t have children?”

“Do you love her?” Abu Mustafa asked.

“Yes,” said Mustafa.

“And how will you feel if you never become a father?”

Mustafa had to think about it. Since the initial shock of the diagnosis, he’d been so focused on reassuring Fadwa, he was no longer sure of his own feelings. “I will be disappointed if that happens,” he said finally. “Probably more disappointed than I can imagine now. But I believe I could learn to live with such disappointment. What concerns me is Fadwa. I don’t know if she’ll ever be able to accept it. Or trust that I have.”

“A marriage without trust is a failed marriage,” Abu Mustafa said. “There’s a simple solution for that.”

“No.” Mustafa shook his head. “A divorce would crush her. It might even kill her. I won’t do that.”

Abu Mustafa smiled sadly. “So what is it you’re asking me, then? How to live with a wife who can never be satisfied? You want my expert opinion on that?”

“Father,” Mustafa said, abashed. “I don’t—”

“No, it’s all right. My answer is simple enough: Be kind.”

Mustafa frowned. He’d been hoping for something more detailed. “Be kind . . . That’s it?”

“If you can do it consistently, you’ll be a better husband than I was,” his father told him. “And Mustafa? If you can’t be kind, be honest. The sooner the better.”

He did what he could. He acceded without complaint to whatever baby-making regimens Fadwa proposed, no matter how hopeless or absurd they seemed. He cultivated patience, and kept his own frustrations to himself, and tried not to be drawn into arguments. But here already he wasn’t being honest, and the problem only got worse.

To help pay for the experimental fertility treatments (all worthless, and each series more expensive than the last) Mustafa began volunteering for extra assignments at work, as much overtime as he could get. This meant being away from home a lot, something that Fadwa couldn’t reasonably object to. She objected anyway, saying that Mustafa was running away from her, which he denied.

The denials weren’t lies, at least not exactly. Yes, there were times when he needed to get away from Fadwa, but his ultimate goal wasn’t escape, it was renewal. Whatever the discontents of his marriage, Mustafa continued to find fulfillment in his work. It wasn’t as easy as it had once been—like many a drug warrior before him, Mustafa had become a cynic about prohibition—but bringing down a villain, avenging (or more rarely, saving) an innocent: These things still gave him a jolt of righteousness, a sense that he was contributing, in some small way, to God’s plan. Sometimes the sense of righteousness was infectious: He’d go home after a particularly good day and Fadwa would smile and laugh and be almost like her old self.

These moments of grace never lasted, and in the long run, the idea that the joys of one sphere of life could compensate for the deficiencies of another was probably poisonous. But it kept Mustafa going for quite a while.

Then in the fifth year of their marriage, at the end of another failed series of fertility treatments, Fadwa fell into a depression that lasted for months. Mustafa went out and arrested Saddam’s chief lieutenant in Anbar Province, catching him red-handed with a truckload of whiskey and convincing him to give up his entire distribution network in exchange for leniency. This was a major coup for Halal Enforcement—a career-making success—but it didn’t improve Fadwa’s mood in the slightest. Mustafa, unable to contain his feelings for once, ended up shouting at her: Why could she not be happy for him?

That night he lay awake, thinking about the wedding party where he and Fadwa had reconnected as adults, wondering what his life would be like if that day had never happened. What if Fadwa’s letter of invitation had been lost in the mail? What if his car had broken down, or he simply hadn’t gone? What if, what if. Of course it might not have made any difference. It could be that he was fated to marry Fadwa no matter what. But it was possible to imagine a world in which that wasn’t so. What if, what if.

He began looking at other women, not in a sexual way (well, not only in a sexual way), but as emissaries from that other world. He tried not to be completely selfish about it: If he got to walk a different path, so did Fadwa, and so he always gave her a husband who was loving and patient and kind and who, most of all, had the wisdom Mustafa lacked, the knowledge of how to make her happy. That being stipulated, his most detailed fantasies all focused on his half of the equation.

A woman in line at the post office; the secretaries at Halal; a mother at the supermarket wrangling three healthy children . . . What if, what if. Or a woman he spied waiting for a bus, sixty if she were a day and obviously plain-looking even in youth, but just as obviously content with her life. What would it be like to be married to such contentment, to see it every morning and every evening, to share a bed with it? What if, what if. And as the fantasy continued to take shape: I wish, I wish.

Such wishing was harmless, he told himself, so long as he remembered it wasn’t reality. He had the wife he had and not another. He wasn’t going to leave Fadwa; he’d sworn that oath a thousand times already and he meant it, even if she didn’t believe him. Nor would he become like Samir, who’d broken off two wedding engagements because of his freely confessed inability to stop womanizing.

But maybe he wasn’t careful enough about keeping his fantasies to himself. Or maybe God wanted to test his resolve. One morning at breakfast Fadwa started telling him about the previous night’s homily in church, which had concerned the prophet Ibrahim’s wife Sarah and her servant, Hagar . . .

Mustafa was only pretending to pay attention, so it was the silence that followed Fadwa’s words rather than the words themselves that caused him to look up. Fadwa was at the kitchen sink with her back to him, standing rigid as though awaiting a physical blow.
