“You’re sure, Mel?”

“I went to the doctor,” she said. “I’m ten weeks along. I heard the heartbeat.”

“You did?”

“Yeah.”

“Jesus,” he whispered. And then he was silent again. What was he thinking? Melanie was pleased to discover that she didn’t particularly care.

“So, anyway,” Melanie said. “I just thought you should know.”

“Know? Of course I should know. I am the father.” His tone was approaching that of an accusation, but Melanie would not be bul ied. He had given up the right to the secrets her body contained when he slept with Frances Digitt. Melanie could close her eyes and picture Frances rounding the bases of the softbal field, pumping her fist in the air.

“I wanted to wait until I’d been to the doctor before I told you. I wanted to make sure everything was okay.”

“How do you feel?” he said.

“I’ve been pretty sick,” she said. “I’m tired a lot, but otherwise, I feel fine.”

“You sound great,” Peter said. “You sound real y great.” He paused, cleared his throat. Melanie listened for the sound of his fingers on the computer keyboard. It would be just like him to check the market or play Snood while he was on the phone with her. But what she heard was silence; he didn’t even seem to be breathing. “God, I can’t believe this. Can you? After al we went through?”

“I know,” she said. “Pretty ironic.”

“You do sound great, Mel.”

“Thanks,” she said. “Okay, wel , I’m on a pay phone so I should probably hang up. I’l see you . . .”

“When?” Peter said. “I mean, when are you coming home?”

Melanie laughed. “Oh, geez,” she said. “I have no idea.” She felt wonderful saying this. She was 100 percent in control. When she got back to the house, she would kiss Vicki and thank her again for letting her come to Nantucket. Tonight, she would kiss Josh, and then some.

“I’l be in touch, Peter,” Melanie said.

“Um, okay, I’l —”

Melanie hung up.

Every morning when Josh walked into Number Eleven Shel Street, he asked himself what he was doing. What am I doing? What the fuck am I doing? The answer was: He was sleeping with Melanie Patchen, a woman both married and pregnant, he was having an affair with her, and he was keeping it a secret not only from Brenda and Vicki and his father, but from Blaine and Porter. He felt the guiltiest, perhaps, when he looked at the two kids, because he wanted to set a good example for them. They were going to emulate him any which way, a fact that would be easier to accept had he not been screwing their mother’s best friend. It was always first thing in the morning, when he saw their round, wide-eyed faces at the breakfast table, that his remorse was the keenest. By ten o’clock at night—which was when he met Melanie at the town beach—it had dissipated enough for him to carry on with his treachery.

How long would it be until they got caught? Josh asked himself this a hundred times a day, though he never put the question to Melanie because she had enough to worry about as it was. And they were very, very careful. Melanie went so far as to climb out her window into the garden rather than leave the house by the front door; she went so far as to straddle the picket fence rather than use the gate. She built a body out of spare pil ows in her bed, and she padded along the side of the road in the grass rather than crunch on the shel s. She arrived at the parking lot of the town beach between ten and ten-thirty; she climbed into Josh’s Jeep, and he whisked her away to one of a dozen secluded spots where they made love either in his car or, if they were feeling brave, on the beach. Twice, Josh had gotten the feeling that they were being fol owed. One time, he had turned down a dirt road that led them deep into the moors, and the other time he pul ed into an empty driveway. Those incidents made Melanie squeal with nervous excitement, and Josh had to admit, his adrenaline surged in a way that was not unpleasant. They were living a movie script—the secret, forbidden relationship complete with dramatic escapes, and the explosive sex that fol owed.

The sex was, in fact, astonishing. It became abundantly clear to Josh that having sex with a girl was one thing and having sex with a woman was quite another. Josh had thought Melanie’s pregnancy would make things weird, or uncomfortable, but it was just the opposite. Melanie was completely in tune with her body, her hormones were flowing, she was always ready for Josh, she craved him. She complimented him, she encouraged him to be creative. Yeah, the sex was a fantasy, Josh couldn’t deny it, but if the relationship with Melanie had been only about sex, Josh would have tired of it. The problem was that the relationship quickly became about more than just sex. Melanie talked to him, she told him things—

real, adult things; she trusted him with details. It was different from the dreck Josh usual y got from girls. When Josh thought about the stupid drivel he was used to hearing from girls his age ( My hair goes frizz-city in this humidity. . . . Ohmygod, look how many grams of fat! . . . Who’s going to be there? That bitch? . . . I downloaded it for free on . . . ), he was amazed his brain hadn’t turned to tapioca. At first, Josh wasn’t sure that hearing about Melanie’s shattered marriage or her quest for a child would be any better, but he was wrong. It was a story that sucked him right in.

A marriage, as you’ll no doubt discover one day, is a pact you make with another person. It’s a vow you take, it’s sacred, or so you believe on the altar. It’s a promise that you’ll never be alone, you’re part of a team, a unit, a couple, a married couple. That’s the dream, anyway, and I believed it. The baby thing was another dream. For most couples, it’s a given. They don’t even think about it and—bam!—pregnant. I thought it would be that way with Peter and me. I always wanted lots of kids. And then we tried and it didn’t happen and people said, Give it time, because what else can they say? And so we kept trying and kept trying, but the more I thought of it as “trying” the more stressful it became and I got sad and Peter got angry because there was nothing either of us could do. So then we went to see a doctor, and I was, of course, thinking there was something wrong with Peter, and Peter was thinking there was something wrong with me. But the frustrating thing was that there was nothing wrong with either of us. We were both perfectly healthy, we just weren’t connecting. So I took fertility drugs, which had unpleasant side effects, and they didn’t seem to be working anyway, so I stopped those, and we tried the holistic approach—powder from rhinoceros horn and making love upside down at midnight during a full moon—and then we just threw in the towel and admitted it wasn’t working. So what were our options? In vitro. But in vitro is tricky—there’s a timetable, they harvest eggs, they take Peter’s sperm, they fertilize the eggs in a laboratory, then they implant the eggs and hope they take root. There’s a lot of hospital time involved, lots of other people, health professionals helping you along, and meanwhile you’re thinking how unromantic it all is, and you’re wondering why you couldn’t just have conceived after three martinis or a weekend in Palm Springs, like everybody else. You start to hate yourself. Seven times I went through in vitro cycles. It was over a year of my life spent holding my breath, basically, and praying—then crying when it didn’t work, blaming myself, blaming Peter. I’m not going to say I was easy to live with—I wasn’t. Peter got tired of hearing about my cycle, ovulation, fertilization, implantation, viable embryos, but that was all I could think about. The real difference between Peter and me was that I kept the faith in our marriage. I thought we were on the same team—in a tug-of-war, let’s say, against whatever forces were working to keep us childless. But then it was like I looked behind me and Peter was gone, I was tugging alone. Or worse. It was like Peter had joined the other team. He and Frances Digitt. He was my dearest love, my best friend, my safe place, my hero, Josh—and then I discovered I was nothing to him. Less than nothing. It was—it is—the betrayal of a lifetime. I thought affairs were only in soap operas. I thought they were only in Cheever. I didn’t know they really happened. I was so fucking naive. Peter is having an affair with Frances Digitt, he is involved with Frances Digitt. You can’t imagine. You just can’t imagine.

She was wrong there. Al he could do was imagine, and when he did so, he found himself hating Peter Patchen. Because what Josh quickly learned was that Melanie was a sweet person, a genuine person, she thought of others, she was kind and vulnerable and trusting. Of course she believed in love that lasted forever, of course she wanted a house ful of children—and she deserved it. The more time Josh spent with Melanie, the more he wanted to help her, to save her. He wanted to be her hero. He realized he’d felt this way from the very beginning—when Melanie fel off the airplane’s steps and he offered her first aid, and then again when she was stranded at the airport and he gave her a ride home. Late at night, when Josh lay sleepless in bed trying to figure out what the fuck he was doing with Melanie, he wondered if there was something in him that needed to be needed—but if that were the case, he might as wel have stayed with Didi. She was the neediest person he knew. In the end, Josh would have to say that he didn’t know what he was doing with Melanie, but he was powerless to stop.
