That Night on Thistle Lane. Carla Neggers

Olivia since preschool. They were gathered in Olivia’s backyard. Fair-haired and pretty, she’d returned to Knights Bridge in the spring to convert her classic 1803 center-chimney house into The Farm at Carriage Hill. In the process, she’d met and fallen in love with Dylan, a former hockey player, now a wealthy San Diego businessman. His arrival in Knights Bridge had turned the out-of-the-way rural Massachusetts town on its head.

      Pushing back stray curls, Phoebe got to her feet. She and Maggie both wore sundresses and sandals, but Olivia had on shorts and an old T-shirt after spending the morning in her gardens. When she’d left Boston, she’d put her graphic design skills and boundless energy to work in transforming her historic house into an idyllic spot for showers, meetings, girlfriend weekends and the occasional wedding—including her sister’s upcoming wedding in September and her own in December.

      “You’ve been awfully quiet, Phoebe,” Olivia said. “Any ideas what we could wear?”

      “I was just thinking...” Phoebe tried to sound casual. “What if you two dressed up as Audrey Hepburn and Grace Kelly?”

      Olivia pushed back her chair and eyed Phoebe with obvious interest. “How would we pull off Audrey Hepburn and Grace Kelly? Do you have something in mind?”

      Maggie, a caterer with two young sons, stood with her iced tea, the sprig of peppermint and wedge of lemon that she’d artfully hooked onto the glass now floating among the ice cubes. She cast Phoebe an amused look. “Do you see me as Audrey Hepburn or Grace Kelly? Either one?”

      Phoebe smiled at her sister. “Sure, why not?”

      “You really do have an imagination,” Maggie said. “What are they, dresses that came in for the vintage fashion show?”

      Phoebe hesitated, framing her explanation. As director of the Knights Bridge Free Public Library, the vintage fashion show was her brainchild, an end-of-the-summer event that would involve the entire community. It would showcase clothing from 1900 to 1975. The various library reading groups were focusing on twentieth-century books, the historical society was helping out, local businesses were donating food and staging materials—it was an all-consuming project that now, finally, was well in hand.

      Phoebe had discovered the tiny hidden room while looking through the library attic for anything she could use for the show. It was as if she’d stepped into a time capsule, a secret hideaway. The room was filled with reproductions of dresses from movies up through the 1960s and from different historical periods—Medieval, Regency, Victorian, Edwardian, Roaring Twenties.

      Who could have predicted such a thing?

      She wanted to know more before she told anyone. Who had set up the room? Who had worked there, left everything behind? Why?

      Did anyone else know about it?

      She’d started volunteering at the library as a teenager and working there in college, and she’d never heard a word about a hidden attic room.

      Finally she said, “Everyone’s been going through trunks and boxes in closets and attics for the fashion show. It’s been loads of fun so far.”

      Olivia nodded. “I helped Gran load up her car trunk with old clothes from her and her friends. They’re all getting a kick out of the idea.”

      “I can think of several dresses that would be perfect for a costume ball,” Phoebe said. “Two in particular. I’m not positive about sizes, but we can alter them if we need to.”

      “Easier to take in a seam than let one out,” Maggie muttered.

      “If we need to let out seams, we could add a strip of similar or contrasting fabric,” Olivia said. “It’s a costume ball. No one’s going to kick us out if our costumes are a little quirky.”

      “You’ll be wearing masks, too,” Phoebe said.

      “Ah, yes. Plausible deniability.” Olivia grinned, obviously liking that idea. “No one else has to know it’s me trying to pass myself off as Audrey Hepburn.”

      “Not as Audrey Hepburn herself,” Phoebe amended. “As one of the characters she played.”

      Olivia laughed. “Well, that just makes all the difference, doesn’t it? Hey, if one of these outfits works, I’m all for it.”

      “Me, too,” Maggie said, with somewhat less confidence. “You’re sure it’s all right? We won’t be stepping on anyone’s toes borrowing a couple of the dresses?”

      “It’ll be fine,” Phoebe said, leaving it at that. “Why don’t you come by my cottage later? We can open a bottle of wine and you can see if the dresses work for you.”

      “What about you, Phoebe?” Olivia asked. “You have to come with us now. We can’t go off to the ball like the wicked stepsisters and leave you sweeping the ashes out of the fireplace. Dylan left a half-dozen tickets. No one will use them if we don’t.”

      Whenever Olivia mentioned Dylan, Phoebe could see how very much her friend was in love with him.

      A happy ending.

      Phoebe’s favorite books and movies were ones with happy endings, and she welcomed a real-life romantic happy ending, as rare as it could be.

      She waved off a bee that had found its way to her. “It’s very generous of Dylan. A neonatal ICU is a great cause, and it’ll be a wonderful night for everyone, I’m sure, but I can’t go.”

      “Why not?” Maggie asked, obviously skeptical.

      “I have things to do.” Phoebe glanced at her watch and winced. It really was later than she expected. “I have to get back to the library. I have story hour, but I’ll be home by six if you want to come by then.”

      “We’ll be there,” Olivia said, then turned to Maggie. “I guess I shouldn’t speak for you.”

      “Wouldn’t miss it,” Maggie said. “I want to see these dresses and I need a costume.”

      Aware of her sister’s eyes on her, Phoebe offered to help clear the table of the iced-tea glasses and plates of tarts they had sampled for possible addition to the Carriage Hill catering menu, but Olivia shooed her away. “You need to get to story hour. The kids will get restless if you’re late.”

      “An understatement,” Phoebe said with a smile as she snatched a tiny apple-pear tart. “This one’s my favorite, but they’re all fabulous. I’m off. I’ll see you later.”

      Instead of going back through the house and disturbing Olivia’s dog, Buster, asleep in the mudroom, Phoebe followed a bark-mulch path through basil, oregano and dill plants soaking up the summer sun, then crossed a patch of shaded lawn and went around the side of the house to the front yard.

      She had the door open to her Subaru, which she’d owned since she’d started commuting to the University of Massachusetts in nearby Amherst, when her sister burst out from the kitchen ell, a later addition to Olivia’s old house. Phoebe didn’t have a chance to get into the car before Maggie flew down the front walk and caught up with her.

      “Phoebe, what on earth is wrong with you?”

      She knew exactly what her sister was getting at. “I pay my own way, Maggie. You know that.”

      “It’s not as if Dylan offered to pay off your mortgage for you. The tickets are his donation to a worthy cause. It looks good if the ball is well attended. It’s great publicity for the neonatal ICU and what it does, and it gets other people thinking about giving. Everyone wins.” Maggie sighed at her older sister. “We can’t be grinds all the time.”

      “I’m not a grind,” Phoebe said. “I love what I do. I have fun—”

      “And you live within your means and never take a false step,” Maggie finished for her, then winced. “Sorry. That came out wrong.”

      “It’s okay. It’s just...” Phoebe stared at the tiny tart in her hand, suddenly wishing
