Aria shivered, her lungs burning from the cold. She wanted out of here, now, but her limbs wouldn’t move. “W-what are you doing here?”
“Just checking out an old haunt,” Courtney said. She leaned against a crumbling structure Aria had never seen before. It looked like a round brick base, overgrown with moss. Half of an A-shaped post still existed, the wood brittle and rotted. A rusty metal bucket lay in the grass nearby.
Aria put her hand to her mouth, slowly filling in the missing pieces. It was a wishing well. Just like the one Ali had drawn on her Time Capsule flag. Her limbs began to shake.
“I used to come here to think.” Courtney perched on the edge of the stone, letting her feet dangle into the well. “It was the only place that was just mine. It’s why I drew it on my Time Capsule flag.”
Aria’s mouth dropped open. Her Time Capsule flag? “Excuse me?”
An owl hooted. A cloud shaped like a hand floated over the moon. Courtney threw a clump of frozen moss down the well. Aria didn’t hear it hit the bottom. “I know Jason gave you the flag.” She turned to look at Aria. “I’m glad you had it.”
Aria blinked fast. “W-what the hell is going on?”
Courtney raised her hands in surrender. “Don’t freak out.” Her voice made a little puff of smoke in the air. “But I’m not Courtney. I’m Ali.”
Aria’s knees buckled. She scrambled backward, slipping on some wet leaves.
“Please don’t run away,” Courtney pleaded. The moon illuminated the whites of her eyes and her ultra-bleached teeth, like a human jack-o’-lantern. “Just let me explain.”
Aria didn’t move as Courtney—or whoever she was—quickly summarized the truth about her sister, the murder, and the switch. “Hanna, Spencer, and Emily all know already,” she concluded. “I knew you’d be the hardest to tell. All that stuff with your dad…” She jumped off the well and approached Aria. She tentatively put a cashmere-gloved hand on Aria’s shoulder. “I was awful to you. But I’ve changed. I want us to be friends again, just like we used to be when we first got together in sixth grade. Remember how awesome it was?”
Aria’s lips felt paralyzed. Was this Ali standing in front of her? It could be possible. Something had been so strange about Courtney from the beginning—she’d known more about Aria and Rosewood than she should have.
Ali stood there, her eyes wide, pleading. “Just think about it, okay? Try to see things from my perspective.”
Aria felt a longing twinge, wanting things to be the way they once were back when they’d first become friends. Things had been awesome for a while: They’d taken tons of trips to the Poconos, spent hours at one another’s houses, made silly movies with Aria’s video camera. For once, Aria hadn’t been a kooky loner but part of a group.
And then Ali pivoted and walked away. Her footsteps crunched loudly for a few moments before fading into the distance.
Aria started back down the hill toward her house. I want us to be friends again. Just think about it, okay? Part of her wanted to tell Ali that bygones were bygones. She wanted a best friend again. But something was holding her back. Could Aria really believe that Ali was sorry for everything she’d done and had changed her ways? She’d been back for only a few days, and she already was telling lies again, pretending she’d never been to Rosewood Day or seen Noel Kahn’s house before. She’d put on a pretty convincing act, blubbering about how devastated she was about her father’s affair. Was it really just to get Aria to open up about her own family dysfunction all over again?
Aria breathed out, the smell of rust and something vaguely pondlike filling her nostrils. Then she noticed something white at her feet and stopped. Something was buried deep in the dirt in the side of the hill.
After a moment’s hesitation, Aria crouched down and pulled at it. Chunks of soil and dead leaves cascaded to the ground as she wrenched it free. It was a tattered envelope. Had the backhoes dredged it up when removing some of the old tree stumps?
She tore the envelope open and plunged her hand inside. Her fingers touched something with hard, square edges. Taking a deep breath, she pulled out two blurry Polaroids. Aria furrowed her brow, her hands mottled purple from the cold. The first was a photo of four girls sitting in a circle on a round rug, their heads down. Candles flickered around them. A fifth girl with long blond hair and a heart-shaped face stood, her arms in the air, her eyes closed.
Aria’s heart started to pound. This looked like one of the Polaroids Billy had taken of their end-of-seventh-grade sleepover.
She examined the second Polaroid. The flash had made a hot yellow circle at the top of the frame. Aria felt wobbly on her feet, and her teeth chattered. Somehow, maybe because of the angle of the camera or the refractive light from the flash, this picture showed not what was happening inside…but outside. There was a ghostly reflection in the window showing a pair of hands and a shadowy, ghoulish face. Whoever it was had blond hair like Billy’s, but the features were softer, more feminine. The image was blurry, but the person’s nose was small and straight, and the eyes were round and rimmed with dark lashes.
Aria could barely breathe. She stared at the reflection until her eyes burned. As much as she wanted to believe that the person in the window looked like Billy, she knew it wasn’t true.
Which meant that someone else had been watching them that night.

IF NOT NOW, EM, WHEN?
The following morning, Emily and her sister Carolyn walked into the Rosewood Diner. Their grueling swimming practice had ended a little early, which meant they actually had time to eat a real meal before school.
