Once they had parked in Sconset, under giant elms showing off their new spring leaves, Dabney poured herself and Agnes a glass of champagne. Dabney wasn’t one to seek solace in alcohol, but circumstances were piling up against her so rapidly that she saw no alternative. She took a nice, long sip of champagne, which sparkled against her tongue. Any second now, she would relax.

She set out the picnic on a card table covered with her yellow linen tablecloth, used only this one day a year.

She realized that she had forgotten to pick up the lemon tarts from the Nantucket Bake Shop.

“Oh my gosh!” she said. “I forgot the tarts!”

Box was uncorking the white Bordeaux. He shrugged. “It doesn’t matter,” he said. “No one ever eats them anyway.”

Dabney stared at her husband. Forbearance, she thought. But emotion overcame Dabney’s sturdy genes: her eyes filled with hot tears. She turned away from Box, and from Agnes and CJ, who now seemed like some hideous two-headed monster, and all the others who were starting to mill on the street. She couldn’t let anyone see her crying about the forgotten tarts. She felt like Clarissa Dalloway, who decided that she would get the flowers for the dinner party herself. This picnic, with the ham, and the asparagus, and the ribbon sandwiches that everyone felt comfortable ridiculing, was Dabney’s picnic. It was an expression of her very self, and yet here was John Boxmiller Beech, the brilliant and celebrated economist, telling her it didn’t matter. Which was the equivalent of saying that she, Dabney, didn’t matter.

She stumbled down the street, wishing she were alone, wishing she were anonymous, wishing-for the first time in her forty-eight years-that she were not stuck on this island where every last person thought he knew her, but where in reality no one knew her.

Oh, something was wrong.

Dabney’s vision was blurred by tears, and by drinking champagne on an empty stomach. She knew she should return to the car and eat a ribbon sandwich. There was a big crowd around the 1948 woodie wagon, which had won Best Car three times in the past decade; this year they had done a Wizard of Oz theme. The police chief, Ed Kapenash, was dressed as the Scarecrow.

Dabney didn’t stop, didn’t turn around, she just kept going. Clarissa Dalloway had survived, but someone at her dinner party had committed suicide. Was that right? And then of course Virginia Woolf had done herself in. She’d walked into the River Ouse with rocks in her pockets.

Dabney felt unsteady on her feet. Her hand was shaking so badly that champagne spilled onto the cuff of her yellow oxford.

She saw him waiting at the corner of Main and Chapel Streets. He was straddling a ten-speed bicycle, the same one he had ridden everywhere as a teenager because there had been no money to buy him a car. He used to ride that bike whenever he met Dabney to be alone. They used to meet in the Quaker Cemetery, they would meet at the old, abandoned NHA property called Greater Light, and they would meet at the high school football field. Their song growing up had been Van Morrison’s “Brown Eyed Girl,” not only because Dabney had brown eyes but because of the line about making love in the green grass behind the stadium. That line had been written for her and Clen.

She knew it was him even though he in no way resembled the twenty-two-year-old she had last seen at Steamship Wharf in 1987. He was bigger-seventy or eighty pounds heavier at least-and he had a mustache and a beard. He was a grown-up, a man.

He was wearing a red T-shirt, jeans, and a pair of black Chuck Taylors. Twenty-seven years later and he still wore Chuck Taylors? In high school they had been the only thing he would spend money on. He had owned five pairs.

Something else was different about him, something off balance. It took Dabney another second to realize that Clen had only one arm. She blinked, thinking it was a trick of the light, or the champagne. But what she saw was real: his left arm was a stump. There was the sleeve of his red T-shirt, and nothing below it.

I suffered a pretty serious loss about six months ago, and I’ve been slowly recovering from it.

He had lost his arm.

Dabney’s vision grew dark at the edges, but there was still color-the red of Clen’s T-shirt and the green glen and weak tea of his Scottish hazel eyes. I could not stay, and you could not go. She couldn’t speak. Nina Mobley would be looking for her, as it was time to judge the picnics. It doesn’t matter, nobody ever eats them anyway. Clen! She wanted, at least, to say his name, just his name, but even that was beyond her. She was in the power of some other force; something had her by the back of the neck and was pushing her down. I hope that “never” has an expiration date. She wanted to ride away on his handlebars. Any second now, she would relax. He was there. It was him.

She did not stop for him. She walked on. Even if she could have spoken, what would she have said? She was unprepared. She wasn’t feeling well. Around the corner, hidden by hedges, she tried to breathe, but found she could not breathe. She heard the sound of breaking glass and realized the champagne flute had dropped to the road and shattered. There was wind in her ears. Her knees gave way.

Blackness.

Silence.

Couple #30: Dr. Gary Donegal and Lance Farley, partners ten years

Dr. Donegal: I started seeing Dabney in 1978, my first year on Nantucket. Dabney was, in fact, my first patient. She was twelve years old; her mother had left the family four years earlier, and Dabney’s father, who was a policeman, was worried about Dabney’s emotional well-being as she entered adolescence. Dabney refused to leave the island; she was convinced that if she left Nantucket, she would die. Or something worse.

“Something worse?” I said.

Officer Kimball then explained to me that the last time Dabney had been off Nantucket was in December 1974, when her mother, Patty Benson, took Dabney to Boston to see The Nutcracker. They had orchestra seats for the evening performance of the ballet and a suite at the Park Plaza afterward. Patty, Officer Kimball said, had come from money and was used to doing things this way. She was also spoiled, selfish, and entitled, he said. A summer person, he said-as if this were the explanation for her unpleasant qualities. He then went on to tell me that Patty Benson had left the Park Plaza Hotel in the middle of the night and had never returned.

“Never returned?” I said.

“Never returned,” he said. He knew Patty hadn’t met with foul play because she had given the hotel’s concierge Officer Kimball’s phone number and a twenty-dollar tip to call and tell him to come to Boston to collect their daughter.

When Dabney awoke in the suite in the Park Plaza, Patty was gone. The concierge sent up one of the chambermaids to stay with Dabney until her father arrived.

Dabney never saw or heard from her mother again. Eventually, Officer Kimball hired a detective and discovered that Patty Benson was living in Texas, working as a flight attendant on the private jet of some oil millionaire.

I realized I had my work cut out for me with Dabney. The refusal to leave Nantucket was a natural response to having lost her mother, to being left behind in a hotel room like an empty shopping bag, or a half-eaten club sandwich.

Dabney was happy enough to talk about her mother. Her mother had grown up spending summers in a big old house on Hoicks Hollow Road. The Benson family had belonged to the Sankaty Beach Club; her mother used to say that tan skin was healthy skin. Her mother liked black-and-white movies with singing and dancing, liked lobster tails on Christmas Eve, and did not care for her husband’s Wharf Rat tattoo. Her mother read to Dabney every night before bed and some nights fell asleep in Dabney’s bed; she promised that Dabney could get her ears pierced on her twelfth birthday, but that the only acceptable earrings were pearls.

Dabney wouldn’t talk about The Nutcracker trip or waking up in the hotel alone or the fact that her mother had not contacted her in two, then three, then four years.

I had seen my share of obsessive-compulsive disorder and agoraphobia and paranoia, but I had never seen a combination of the three the way they presented in Dabney. I am, perhaps, making things sound worse for her than they were. She was an exceptional child, and as she grew into a teenager, she only became more exceptional. She was lovely to look at, intelligent, clear-eyed, perceptive, kind, poised, articulate, and funny. But when it came to leaving Nantucket, she had a blind spot. She wouldn’t leave the island unless her life depended on it, she said.

I met with her twice a month. We tried antianxiety medications, none of which proved very effective, but we finally made enough progress that when she was accepted to Harvard, she said she would go.

Even I was surprised by this.

She said, “I told you that I wouldn’t leave the island unless my life depended on it, and now my life depends on it. Am I supposed to stay here and wait tables? Work as a nanny? I have to go to college, Dr. Donegal. I’m smart.”

I agreed with her wholeheartedly: she was smart. I was sure that when she got to Harvard, she would realize there was nothing to fear. No one else would disappear.

This didn’t end up being quite true. Her boyfriend, Clendenin Hughes, went to Yale and became engrossed in his studies and his life there. Dabney traveled once to New Haven to see him, and it ended badly. Officer Kimball was working double shifts that weekend, and hence I was dispatched to go get her.

It was on the ride from New Haven back to the Cape, eight years after our therapy started, that I finally got Dabney to talk. She started with things I knew: she was fatally in love with Clendenin Hughes-“fatally” meaning she was pretty sure the love would kill her, or the fact that he didn’t love her the way she loved him would kill her. He wanted to go places and see things, and she couldn’t, and he didn’t understand, and she couldn’t explain. New Haven had changed Clen, she said. I told her that going new places did sometimes change a person, new experiences shaped us, and Dabney said that she liked who she was and was determined to stay that way. She had not been changed by Cambridge, and I suggested that was because she hadn’t truly let Cambridge into her heart. She didn’t respond to this, and the next time she spoke, she told me that the night her mother left, she told Dabney that she was woefully unhappy with her life. She was no longer in love with Dabney’s father; she had been blinded, she said, by the romantic notion of a war hero. She used to love Nantucket as a summer haven, but living there year-round had spoiled it for her. She hated it now with every cell of her body. She felt like a coyote in a trap, she said. She would chew off her own leg to escape.
