Mr. Kahn kissed her lightly on the lips. "There's no use for us both to get soaked. I won't be long."

He shut the front door, and his car engine roared. Mrs. Kahn and Eric disappeared into the den, and Noel excused himself to the bathroom, leaving Aria all alone in the cavernous kitchen. The huge house was suddenly very still and overwhelming, the only sound the pounding rain against the roof. Suddenly thunder crackled, and the room went dark. Aria screamed. "Noel?" she called out, feeling along the walls.

Somewhere in the distance, someone-Naomi, maybe-giggled. Another clap of thunder sounded, shaking the pots and pans hanging over the island. Lightning lit up the room. For a split second, Aria was sure she saw a pair of eyes staring at her from outside the back window. She screamed again.

Then the lights snapped back on with a spark. The refrigerator hummed calmly, the recessed lights cast a peaceful yellow glow over the room, and the eyes at the window were gone. When Aria looked down, she saw that her cell phone, which was nestled in her pocket, was blinking. She grabbed it and swallowed hard. One new text message from Anonymous.

She pressed READ, dreading what she might see.

It was a picture of a blond-haired woman applying cherry-red lipstick in the front seat of a car. The woman wore a blue oxford shirt and an expensive gold watch-the same ones Mr. Kahn had worn during the pool game. Add in his telltale bushy eyebrows and straight mouth, and anyone would know it was him. The clock on the dashboard of his car said 1:35-three minutes ago. The tall, iron eagle on the post in the corner of the picture was the eagle at the Kahns' front gate. He'd put on the wig before he'd even left the property.

Aria ran to the window, certain she'd see someone lurking at the end of the driveway, but there was no one there. Sweat beaded on her forehead. No.

"Aria?" Noel called from the hall. "Are you okay?"

Aria dropped the curtain and whipped around. Noel was walking toward her. She fumbled for the ERASE b.u.t.ton on her phone, not wanting Noel to see the picture, but her finger b.u.mped the right arrow instead, bringing up a note that went with the picture. As Aria read it, her heart stopped dead.

Secrets are such a drag. Break up with your loving boyfriend, or this pic goes public. -A

18.

THE HOME OF HER DREAMS.

"Welcome to the open house!" a cheery realtor with a stiff black hair-helmet said as she ushered Emily and Aria through the open door of 204 Ship Lane. She thrust a square business card into each of their hands. "My name is Sandra. Have a look around!"

Emily turned the card over. Let me find you the home of your dreams, Sandra's slogan read. "Actually, I was wondering-" she started, but Sandra was already attending to a new couple who had come in after them.

Shaking out her umbrella and pushing back the hood of her raincoat, Emily stepped into the foyer of the house she'd obsessed over for the past seven months. It was empty, and only a few hints of the Bakers remained. The air smelled like a peppermint candle and Windex. The walls were painted a cheerful blue, and in the open closet was a blue plastic wrapper for the Philadelphia Sentinel. There were tiny scratches in the golden wooden floor from dog toenails, and someone had left a G.o.d's-eye string ornament hanging over the door.

Emily stared at the bra.s.s strip that separated the tiled foyer from the wooden living room floor, afraid to step any further into the house. Was she really ready to see this place?

Aria turned to Emily, as if sensing her apprehension. "Are you okay?"

"Uh huh," Emily said woozily. "Thanks for meeting me here."

"No problem." An uneasy look swept over Aria's face, but when she noticed Emily looking at her, she quickly smiled again.

"Are you okay?" Emily asked.

Aria's jaw trembled. "I don't want to bother you with it. You've got enough going on."

Emily rolled her eyes. "Come on. What?"

After a moment's hesitation, Aria leaned in closer, her feather earrings brushing against Emily's cheek. "Well, okay. I got a note from A about an hour ago."

Emily's mouth dropped open. "What did it say?"

Aria pressed her glossy lips together. "It doesn't matter. Just some stupid stuff. But I was at Noel's house, and A took a picture of something at the end of Noel's driveway. A was so close, and I missed seeing who it was."

A shiver snaked up Emily's spine. "Remember the note I got on my car at the covered bridge? The one with the picture of me and Tabitha? A was close then, too."

Aria skirted out of the way of two more people who had come through the front door. "How is it that we keep missing A? And how does A always know where we are?"

"Ali would always know where we were," Emily said quietly.

Aria's shoulders lowered. "Em, A isn't Ali. There's no way."

Emily shut her eyes. She was so sick of having the same argument over and over. But she couldn't explain why she was convinced Ali wasn't dead-she'd have to confess that she'd left open the door in the burning house in the Poconos.

Aria stepped into the living room. The blue carpet had deep indentations from where the furniture had stood. "A is definitely Gayle, Em. Remember how weird she was that day at the cafe? She's totally capable of stalking us."

"But it makes no sense." Emily glanced over her shoulder to make sure an elderly couple in matching argyle sweaters wasn't listening. "Gayle has no connection to Jamaica. How could she know what we did?"

"Are you sure you didn't say anything to anyone?" Aria asked. "What about that friend of yours, Derrick? He worked for Gayle, right? Are you sure you didn't slip and tell him anything about Tabitha?"

Emily whirled around and glared at Aria. "Of course not! How could you even think that?"

Aria held up her hands in surrender. "I'm sorry. I'm just trying to cover all the bases."

Sandra's voice rang out in the other room, telling a potential buyer about the square footage and the kitchen upgrades. Emily tried to swallow her annoyance, knowing Aria wasn't trying to accuse her of anything. She wandered out of the living room and up the stairs to the second floor. The master bedroom was the first room on the right.

The room was painted a dusty gray and had wooden blinds on the windows. Emily could picture a bed on one wall, a dresser on another. But she couldn't picture the Bakers living within these walls. Were they late sleepers or early risers? Did they snack on cookies and potato chips in bed, leaving crumbs in the sheets? How many tears had they shed over not being able to have a child?

It was one of the first things the Bakers had told Emily when she'd met them-they'd been trying for over four years to no avail. "We both work with kids all day, and we'd love to have some of our own," Mrs. Baker had said earnestly. "We've always wanted to be parents." Mr. Baker's fingers gripped his wife's hand hard.

Now, Emily walked the perimeter of the room, touching the light switch, tracing a tiny crack in the wall, and poking her head into an empty closet. She could only imagine how overjoyed the Bakers had been when they'd found out she had chosen them as her baby's adoptive parents. They'd probably lain in bed at night, dreaming of their child, fantasizing about swimming lessons, vacations, and the first day of school. Then she imagined the Bakers' shock when they found out Emily had changed her mind. She'd asked Rebecca, the adoption coordinator, to pa.s.s on the message-she'd been too chicken to tell the Bakers herself.

Rebecca had been confused. "So . . . you're keeping the baby?" she'd sounded out.

"Uh, I've just come up with another option," Emily said evasively, not wanting to admit that she'd found another adoptive parent-or that Gayle had offered her a lot of money.

The coordinator called back a little later and told Emily that the Bakers had been very gracious with her decision. "They want your baby to have the best home possible, and if you think that's somewhere else, they understand," Rebecca said. In some ways, it disappointed Emily: She would have rather they'd been furious at her. It was what she deserved.

Emily had thought about the Bakers a lot after she made the decision to give the baby to Gayle, especially after Gayle started calling Emily nonstop. Every time Emily's phone rang, it was Gayle, checking in. At first, Emily indulged her, rationalizing Gayle's rapid speech, her shaky laugh, her nervous questions. She was just excited, right? She tried to justify why she hadn't met Gayle's husband, the potential father, yet-Gayle said he was really busy, but he was one hundred percent on board. When her phone started ringing every hour, Emily let the calls go to voicemail, the uneasiness growing sharper and more acrid inside her. Something wasn't right. She began looking for ways to get out of the deal. She dreaded the day she'd have to give the baby up.

The final straw came two weeks before Emily's scheduled C-section. Derrick had asked Emily to pick him up at Gayle's house after work one Sat.u.r.day; they were going to go to the Camden Aquarium. Emily hadn't told Gayle she was coming; she was too tired to deal with her. After parking the car in the long driveway, she'd walked up to the front door and looked through the window. Gayle was standing in the foyer with her back to Emily, talking on the phone. "Yes, it's true," she was saying into the receiver. "I'm having a baby. I know, I know, I've barely gained any weight, but I guess I'm one of those lucky pregnant people."

Emily had nearly tumbled off the porch. What kind of crazy person pretended they were pregnant when they really weren't? Was she going to try and pa.s.s off Emily's baby as her own? It left a horrible taste in her mouth. The Bakers had told Emily that the child would know she'd been adopted. They'd even tell her about Emily. What else would Gayle lie to the baby about?

She'd fled back to her car, revved the engine fast, and driven away, too upset to even leave a message for Derrick. Everything was so clear in that moment. There was no way Gayle was getting her baby. The money didn't matter. The privileged life the child might lead in Gayle's care didn't matter. And so, the next day, she called Gayle and told her that the doctor had rescheduled her C-section for two days later than originally planned. Then she'd called Aria, Hanna, and Spencer, asking for their help.

"Emily?" Aria called now. "Em, you have to come see this!"

Emily followed Aria's voice to a smaller bedroom down the hall. "Look!" Aria said, spreading out her arms.

Emily spun around. The walls were striped with green and yellow paint. On the far wall was a mural of a circus train, a lion, tiger, elephant, and monkey peeking out of the cars. Above the mural was a decal that said Violet, the o a smiley face, and the t sprouting a flower out the top.

"It was her room," Aria whispered.

Tears filled Emily's eyes. She remembered the Bakers telling her that they'd designed a nursery for the baby in gender-neutral colors, leaving a s.p.a.ce on the wall for a boy name or a girl name. They hadn't told Emily their choices, though, saying they wanted to see what the baby looked like before they made a final decision. The name Violet, she thought, was perfect.

"It's so beautiful," Emily whispered, walking to the little window seat and settling on the cushion. There were still marks where the crib and changing table had stood. When the Bakers found the baby seat on their doorstep, had they brought her in here to sleep? No, Emily decided. Not that first night. They'd probably held the baby until the sun came up, amazed she was theirs. Scared, too. They'd probably made plans to move that very night to avoid questions and to make sure the baby wouldn't be taken away.

Suddenly, Emily knew something for sure: The Bakers had done everything they could for the baby. They'd uprooted their lives just to ensure they could keep her, her happiness meaning more than their community, their home. That was worth more than any amount of money. She had made the right choice giving her daughter-Violet-to them.

"Hey," Aria said soothingly, noticing Emily's tear-streaked face. She wrapped her arms around Emily and squeezed tight. Emily hugged back, and they remained that way for several minutes. She felt happy and sad at the same time. It was wonderful to know that the baby had such a loving home, but she hated that she still didn't know where the Bakers had gone.

Emily broke from Aria's embrace and started down the stairs to find the realtor, suddenly fueled with purpose. Sandra was in the kitchen, rearranging papers in a binder.

"Excuse me," she called. Sandra turned, a plastic smile frozen on her face. "The family that lived here before. Do you know what happened to them?"

"If I recall, they left in early September, I believe." Sandra flipped through a file folder containing information about the house. "Their names were Charles and Lizzie Baker."

"Do you have a forwarding address?" Emily asked.

Sandra shook her head. "Were you the one who e-mailed me about this?"

"E-mail?" Emily raised an eyebrow. "No . . ."

Sandra whipped out her BlackBerry and scrolled through it. "That's funny. I got an e-mail asking the same question. Someone else was eager to know where the Bakers went, too."

Aria, who had just arrived in the kitchen, coughed. "Do you remember who sent the e-mail?"

Sandra stared at her BlackBerry. "I swore I had it on here, but maybe I deleted it. It was a woman's name, definitely. Maybe it started with a G?"

"Gayle Riggs?" Aria blurted.

Sandra's face lit up. "Yes, I believe that's it! Do you know her?"

Emily and Aria exchanged a haunted look. Emily had never told Gayle who she'd originally chosen to give the baby to. The adoption agency would never have given out that information, either. What if she'd found out, somehow? What if A had told her? And what if-Emily's heart started to pound-Gayle was trying to track the baby down?

Suddenly, a ping sounded from inside Aria's bag. She pulled it out and looked at her phone. "Hanna says she's been trying to contact you, Em."

Emily reached into her pocket for her phone and studied the dark screen. "The battery's dead."

Aria's eyes were still on her phone. She hit a b.u.t.ton and gasped. "Look at this." She pa.s.sed it to Emily. Tell Em it's urgent, a text from Hanna said. I think Gayle is after her baby. Call me ASAP.

"Oh my G.o.d," Emily whispered.

Another ping sounded as a new message arrived on Aria's phone. The sender was a jumble of letters and numbers. Aria clapped her hand to her mouth. Emily's heart thudded fast as she read the words.

Guess Emily's not the only one looking for that little bundle of joy. Who's going to get there first? -A

19.

SECRET AGENT HANNA.

The thing about camo, Hanna realized, was that it was really ugly. There should be Louis Vuitton camo or camo that actually complemented one's skin tone. It wasn't like she was hiding out in the green and brown woods, after all. She was lurking in the King James Mall.

It was a little later on Sat.u.r.day afternoon, and Hanna had just put on her first-and last-camouflage outfit to kick off Operation Figure Out If Colleen Is Hiding Something. She'd bought the outfit at the Rosewood Army/Navy, a terrifying store full of gas masks, grenade holders, unflattering combat boots, and other sundries she hoped to never see again, except maybe on CNN. She'd also picked up a field scope that had scratches on it (probably from some scary war), night-vision goggles, and a platoon helmet, just in case she had to do a commando roll or jump out of a moving car. Perhaps it was overkill to buy all that equipment to spy on a girl who'd probably be delighted if she knew Hanna had taken such an acute interest in her, but Hanna thought it would help her get in the mood.

Now, she was crouching behind a large fake plant in the middle of the esplanade and peering through the binoculars at Colleen and Mike strolling into Victoria's Secret. Hanna felt a moment of misgiving. Was it weird that she was doing this? It was sort of like she was becoming an A herself. But then, maybe Gayle was right-maybe Colleen had a secret she didn't know about. Everyone did.

Hanna checked her watch. She would give it another half hour, she decided, and then call Emily again. As for the Colleen thing, it wasn't like she and Gayle were on the same team or anything-A just had a good idea for once. All she needed to do was unearth some embarra.s.sing secret of Colleen's to turn Mike off her for good and kick her back to dork-dom where she belonged.

There was only one problem: so far, Colleen seemed like an open book. Hanna had peeked in Colleen's car in the parking garage, but she kept it tidy and boring. She'd followed the couple to Otter, the best boutique in the mall, and watched as Hanna's favorite salesgirl showed Colleen a brand-new style of James jeans that had just come in-jeans that Hanna was supposed to see first. Traitor.

Now, Colleen approached the Victoria's Secret salesgirl and explained she was looking for some new lingerie. "What size are you?" the a.s.sistant asked. Hanna had learned how to lip-read when she was in fifth grade, mostly to decipher her parents' tense fights through the gla.s.s back-patio door. Colleen gave her the answer, and Hanna's jaw dropped. Colleen's b.o.o.bs were even bigger than she had thought.

As the salesgirl searched for some styles Colleen might like, Mike wandered over to a table of satin bras, held an enormous pink one to his chest, and started striking exaggerated poses. Hanna snickered. Mike used to do that all the time when they went shopping together, and it never failed to crack her up. But when Colleen saw him, a disapproving scowl settled over her features. Mike pouted and dropped the bra back to the table, looking like a scolded puppy.

Hanna's phone chimed loudly, and she frantically patted her pocket to silence it. Aria's picture was flashing on the screen. "Did you get in touch with Emily?" Hanna whispered into the receiver.

"I'm with Emily, and I've patched in Spencer, too." Aria's voice echoed on speakerphone. "We're really freaked. I got a note today. A is definitely after Emily's baby."

Hanna sank down further into the bushes. "We have to prove Gayle is A. But how do we do that without going to the cops?"

"Gayle's psycho," Aria explained. "Just like Kelsey. The cops wouldn't believe anything she says."

"Yeah, but she has money," Hanna reminded her. "And she's an adult. That holds some weight, don't you think?"

"Guys, I'm not so sure Gayle is A," Spencer's voice sounded far away. "I got a note last night, and I'm at Princeton. How could Gayle be in two places at once?"

Hanna watched as a bunch of kids from Rosewood Day pa.s.sed. "Maybe she can be. At the race this morning, Gayle apologized for being late, saying she'd just come from Princeton. Her husband just donated some cancer lab."

Spencer made a small noise at the back of her throat. "Do you think she followed me to my party? Wouldn't I have noticed someone like her in a crowd of kids?"

"She was probably hiding in the bushes outside," Hanna said.

"That still doesn't prove Gayle is A," Emily protested. "But the important thing is, either way, she's after the baby. How are we going to find out where the Bakers went? We need to warn them."

"The realtor didn't have the information on where they moved," Aria added, sounding despondent. "They could be anywhere."
