"What's that on your neck?" He asked her.

Jacqui blushed.

They returned home hoping not to run into Anna. No such luck. She had just returned from the salon and pulled up to the house at the same time.

"Anyone care to explain?" She demanded when she saw William.

"Um, it was the sunscreen. I don't think it was strong enough," Eliza said smoothly.

"But he's fine," piped in Jacqui. "Right, Will?" William just smiled and pointed at her hickey. He was definitely fine.

"Drugstore brands are really ineffective," Eliza said, playing up to Anna's snobbishness. "There's a really good one from Zurich that is divine."

"Order some for tomorrow," Anna allowed, and turned away without even saying hello to any of the children.

The three breathed a sigh of relief. And then William ran off, as though nothing had happened at all.

the girls have finally learned how to locate the fridge under all that french cabinetry.

TWO WEEKS AFTER THE TWINS DITCHED HER BEFORE the PlayStation2 party, Eliza stood by the washbasin in the laundry room, trying to get the mud off Sugar's Escada tennis whites. This was so not what she had prepared for when she told Kevin Perry she would "help out with the kids" this summer.

Poppy and Sugar's snub had hit Eliza hard, but she still managed to claw her way back into the scene through her old friends Taylor and Lindsay, who had instant access to every guest list event in town, from store openings to movie premieres. The three of them hit a different nightclub every night, all while Eliza strategically avoided the Perry twins. It was harder to pretend they didn't exist back at the house, where the blond brats kept her busy with countless mundane tasks. Eliza didn't mind so much since it appeared Sugar and Poppy had failed to mention her diminished status to anyone in the clique. Were they being nice or just indifferent? Eliza couldn't hazard a guess, but she was thankful for the reprieve in public, at least.

"There," she said, holding the soiled cloth up to the light. "That should be good enough."

She had ruined her manicure in the process, but at least she wouldn't wake up tomorrow morning to hear Sugar's hoarse voice asking her ever so sweetly why her tennis skirt wasn't hanging in her closet. She walked out to the kitchen, where Mara was sitting in front of a bowl, her forehead knit in concentration as she carefully balanced a small green object on her fingers.

"What are you doing?" Eliza asked.

"What does it look like I'm doing? I'm peeling Madison's grapes," Mara explained, as if it were the most normal thing in the world.

"Hell no." Eliza still couldn't believe some of the things they had to do for these kids.

Mara gingerly took an edge of the grape and peeled off its skin. The bowl in front of her held about two dozen similarly skinless specimens.

"Where's Jacqui?" Eliza asked.

"Feeding Cody dinner. It's her turn." And for once Jacqui was actually there to do it.

Eliza made a face. Talk about a thankless undertaking. The girls had learned not to stand in the line of fire when Cody hurled after every meal. Two words: projectile vomit.

"MERDA!" Jacqui stormed into the kitchen from the dining room. A river of green-colored puke ran down the length of her cotton dress. "Why does everything he eats have to be hand chopped?" she ranted. "Has this woman never heard of baby food? This makes his stomach virada!"

They grunted in sympathy.

Madison walked in and helped herself to a grape. "Bleh," she said, spitting out a chewed-up mess.

"What's wrong now?" Mara sighed.

"They're not cold enough. And that one still has its skin on a little bit."

Mara wanted to throw her hands up in despair. Madison's grapes were never cold enough or peeled properly or else could not be eaten because they were deemed "funny looking." Mara knew the kid was just rebelling against the strict diet her stepmother had put her on, but it was seriously making her own life difficult.

"There's nothing wrong with them," Eliza said, taking one and popping it into her mouth. "Yum. I wish I had somebody to peel my grapes. You're a lucky girl."

Madison looked at Eliza doubtfully but began to eat the grapes without complaint. A miracle.

The door swung open again and this time Anna walked into the kitchen. The three au pairs froze, wondering what was wrong now.

"Has anyone seen the mail?" She asked.

They shook her heads. Laurie had told them that Anna was desperately waiting for an invitation to a dinner party at Calvin Klein's house. Unfortunately, it had yet to arrive.

"Anna? Could we ask you something?" Mara assayed.

"Yes?"

"The kids keep talking about these other girls-who, um, used to take care of them? Do you know what they're talking about?"

"Some girls named Camille, and Tara, or something," Eliza added.

Anna scowled. "Yes. They used to work here. But we don't talk about them," she said sternly. "Do you understand?"

They nodded. Obviously, the former au pairs were a sore subject. But the girls' curiosity was doubly piqued. What had they done that was so bad? If only someone would tell them. It obviously hadn't been letting one of the kids fry like a potato chip. They'd done that and they were still here. But they had to find out, because as all three of them agreed, they couldn't afford to make the same mistake.

After cleaning up the kitchen and putting the kids to bed, the au pairs staggered back to their dingy room.

"God! What a week!" Eliza said, flopping into the only armchair. Between the cooking and the cleaning and the scrambling out of a VIP room whenever she spotted any sign of the twins' blond heads, Eliza was exhausted.

"Seriously," Mara agreed, thinking about the week spent catering to the whims of four adorable but very spoiled children.

Jacqui had disappeared into the bathroom to change. She was meeting Luca for dinner at The Laundry, a romantic French restaurant.

Eliza looked at the clock. It was nine. Too early to hit the clubs yet. "You know what? We deserve a little break."

"What have you got in mind?" Mara asked.

Eliza smiled mischievously. "Look what I found." She grinned, holding up an antique key that just happened to unlock the Perrys' liquor cabinet. It was about time they had a little fun.

the best way to find out a secret? a bottle of grey goose and a game of truth.

AN EMPTY VODKA BOTTLE ROLLED DOWN THE THREADBARE carpet.

"Here's another one." Eliza hiccupped, grabbing another bottle from her bag.

"No thanks-I'm done," Mara said.

"No way, if I'm having another, everyone else is, too."

Jacqui held up her glass. She wasn't one to argue with that.

Stealing a couple of bottles from the Perry stash seemed totally appropriate, given how they had been slaving away. It was sort of like a bonus, Eliza had told herself.

"Let's play truth," Eliza decided, and spun the bottle around.

It stopped in front of Jacqui.

"What do you want to ask me?" Jacqui asked, thinking the game was sort of fun for being a little wicked. Plus Luca had called earlier to say could they meet at eleven for drinks at Turtle Crossing instead, so she had lots of time to kill with the roommates.

"Have you ever been in love?" Eliza asked, thinking she would start it off easy.

Jacqui blew out a puff of smoke and considered the question. "Of course."

"Are you in love now?" Mara asked.

"Maybe," Jacqui hedged.

"The game is called TRUTH!" Eliza said.

"Okay, okay. Yes. I'm in love." Jacqui giggled. She told them about Luca, the guy she had come all across the globe to be with, and how they had gotten reacquainted very, very quickly. It was the same as it ever was. Or was it? She didn't tell them, but Luca never took her out on proper dates. Instead they spent an awful lot of time in his bedroom or in dingy, out-of-the-way crab shacks in the North (known by most as the "Wrong") Fork.

"I'm just not digging the scene this year, Jac," Luke had explained one evening when they were getting ready to drive all the way to some ramshackle bar on Shelter Island for what he called "the best hamburgers in the Hamptons." Jacqui didn't think the burgers at the Dory were anything to write home about, but she had found her man and as long as they were together, she was happy.

Jacqui spun the vodka bottle, which pointed toward Mara.

"Shoot," Mara said. "Ask me whatever you want."

"How many guys have you slept with?" Eliza asked with a grin. She wanted to shake Mara up a little. The girl was so uptight sometimes.

To Eliza's surprise, Mara merely rolled her eyes. "One."

She told them about Jim, her boyfriend back home, not that it had escaped her roommates' notice that all Mara seemed to do after work was log on to her laptop to send him e-mails or else max out her mobile minutes to chat to him every night. As if it was doing her any good. Even Jacqui could see that every time Mara set her eyes on Ryan Perry, she got all flustered.

"So how was he?" Eliza giggled.

"I don't believe you guys get follow-up questions!" Mara huffed.

"Not that good, huh?" Eliza teased. She was in a good mood after three vodka tonics.

"How many guys have you slept with?" Mara demanded.

Eliza blushed. "It's not my turn!"

"C'mon, how many?" Jacqui asked, curious.

"I'm not telling."

"TRUTH! TRUTH! TRUTH!" Mara demanded.

"All right-fine. None," Eliza said challengingly.

"Wow." Jacqui and Mara raised their eyebrows. Now things were getting interesting.

"I almost did once. With my boyfriend Charlie." Eliza's face softened. "It was our six-month anniversary, and he'd just given me these earrings," she said, touching her ear. "I had bought this really cute little outfit from La Perla."

"What happened?"

"He'd rented a room at the Carlyle, but when we got up there, he fell asleep from all the wine at dinner," Eliza said. "Then we broke up the next week, so we never got a chance."

"What happened?" Mara asked.

"Things got-uh, complicated," Eliza said. "I had to go away."

"Were you in love with him?" Mara asked.

"Yeah-I think so," Eliza said. She certainly loved being Charlie Borshok's girlfriend, if not Charlie himself. There were so many perks that went with the title. The gifts (always hand-delivered by special messenger). The vacations (weekends in Locust Valley, skiing in Telluride, surprise jaunts to St. Bart's). The flat-out envy of everyone in the sophomore class.

"Do you guys keep in touch?" Mara asked.

"Not really. But he's in the Hamptons this summer," Eliza said. "I'm sure I'll bump into him one of these days."

"Maybe you guys will get back together," Mara suggested. She couldn't help it; she was a romantic at heart.

"We'll see," Eliza said. "I heard he's already dating someone else." She looked at her cell phone for the time. "I've got to get ready!"

"Where are you going?"

"There's some benefit for baby teeth testing at Trupin Castle. It's this huge mansion this guy built in Southampton; he broke, like, all the zoning laws to do it. I heard he paid six million in fees. Anyway, it's never been open to the public and the new owner just got it renovated."

"How do you keep getting into all these things? Don't they card?" Mara asked.

Eliza took a puff from her cigarette and placed it on a makeshift ashtray (an upside-down Bumble and Bumble styling wax top). "I've got a fake ID. And it's a private event. As long as you're on the list, it doesn't matter. It's two hundred bucks a head, but Kit gave me three tickets. You guys wanna come?" The tonics and secret sharing were making Eliza feel surprisingly benevolent. Maybe these other girls weren't so bad after all, she thought.

"No, I'm meeting Luca," Jacqui said.
