The other thing that only Hope knew was that, although Allegra had been dating Brick Llewellyn for the past two years, she was cheating on him with Ian Coburn, a rich kid who had graduated from Nantucket High School the year before and who was now a freshman at Boston College.

To Hope’s knowledge, Allegra had seen Ian three of the past four weekends. Allegra was supposed to be flying over to the Cape every Saturday to take a fancy, expensive, guaranteed-to-get-results SAT prep course at the community college, but Allegra had ditched the class, and Ian picked her up in his red Camaro and they “drove around,” whatever that meant. This past weekend, they had gone to the Cape Cod Mall, where Ian bought Allegra three Chanel lipsticks from the makeup counter at Macy’s; then they enjoyed a long, boozy lunch at the Naked Oyster, Allegra using a fake ID saying that she was a twenty-seven-year-old resident of Grand Rapids, Michigan. Allegra had asked Hope to cover for her—both with Brick and with her parents. She had offered to pay Hope, or lend Hope the fake ID, even though Allegra and Hope both knew Hope would never need it.

Hope agreed, but not because she wanted the ID or the money.

She wanted Brick.

For two years, Hope had assumed there would be no way Brick would ever break up with her sister. They would be one of those couples who grew up together, made it work long distance through four years of college (if Allegra got into college, which at this point seemed doubtful), and then married, had children, and found themselves celebrating their fiftieth wedding anniversary. Although Brick might have shared this vision, what neither he nor Hope had considered was that Allegra was Allegra, which meant not smart enough to know a good thing when she had it. Allegra was a seeker and a climber and an opportunist, and she had a short attention span. Allegra would get caught with Ian Coburn, and that would be the end of her and Brick. Hope just had to wait.

Hope and Brick texted each other regularly about their honors chemistry homework, a fact that Hope did not share with her sister, and she knew Brick didn’t either. Allegra hadn’t been selected to take honors chem; she was in regular chem with other underachievers like Hollis and their friend Bluto.

At five thirty, when Hope knew Brick would be home from baseball practice, she shot him a text: Hot glass looks like cool glass. This was how they started every conversation about their chem homework, an inside joke referring to the enormous sign hanging over the Smart Board in their classroom. Mr. Hence lived in mortal fear of one of his students picking up a beaker that had recently been over the Bunsen burner.

No response. Maybe Brick wasn’t ready to tackle chem yet. Maybe he was taking a shower or hanging out with his parents. Brick liked to spend time with his parents—whereas Hope, and especially Allegra, avoided it like the plague—because Trevor and Madeline were so cool, and the three of them in their family were, like, friends.

Sometimes Hope thought that she might not want to date Brick as much as become his adopted sister.

She texted: Have you looked at the questions on page 242? Inert gases?

No response. Hope could send two unanswered texts but not three. That would make her look desperate and pushy.

A second later, her phone pinged.

Brick wrote, Was your sister really at class on Saturday? Or did she ditch and go to the mall?

Hope ogled her screen. Here it was, then, at a time she least expected it. Brick was on to Allegra. It was all Hope could do not to spill the beans.

She wrote: Class, I think. Why?

Brick wrote: Someone said they saw her at the mall.

Hope wrote: Which someone?

Brick wrote: Someone.

Hope wrote: Come on. Who.

Brick wrote: Parker Marz. He said she was with some guy in a Boston College sweatshirt. Doesn’t your cousin go to BC?

Hope chewed her pencil eraser. Her cousins were all older, although one of them—the biggest, most pompous jerk of the bunch—had gone to BC, prompting Eddie to tell his favorite joke. How do you know if someone goes to BC? They’ll tell you.

Hope wrote: One of our cousins went to BC. A while ago.

Brick wrote: Oh. Okay.

Hope wrote: Did you ask Allegra about it?

Brick wrote: Nah. Not a big deal. Never mind.

Burying his head in the sand, Hope thought. She couldn’t blame him. The truth was too awful to contemplate.

Hope went to church every week with her mother. She was a spiritual person, she believed in God, she bought most of the tenets of the Catholic Church but not all of them. She did believe in prayer, and so she said a heartfelt one for Brick, and then she opened to page 242 and started learning about the inert gases.

EDDIE

He bounced up the cobblestone street in his Porsche Cayenne, wearing his lucky Panama hat, waving at everyone he saw. Grace liked to accuse him of what she called “indiscriminate waving.”

“You didn’t even know that person,” she said once. “Why did you wave?”

The fact was, Eddie was a little nearsighted, and he feared not waving to the wrong person more than he feared waving to a complete stranger. A not-wave in the real-estate business could mean a killed deal or a lost rental; it could mean missing out on thousands of dollars of potential income.

Next to Eddie, on the passenger seat, were four bills from the spec houses on Eagle Wing Lane. Or, more correctly, four bills from 13 Eagle Wing Lane, because Eddie had been forced to stop construction on numbers 9 and 11. He simply didn’t have the cash.

Getting four bills in one day should be illegal, Eddie thought. Three should be the maximum. But today’s mail had brought four; his secretary, Eloise, had handed them over, pinched between her thumb and index finger, as if she were giving him someone’s snotty handkerchief.
