Caleb Devlin is a legend on Mockingbird Lane, the boy who terrorized an entire town before he got sent away. They say he hurt other kids, tortured animals, set fires, and did things grown-ups speak of only in whispers. But that was all before Penny and her little brother moved here.

Now Caleb's back, older and more dangerous than ever, and terrible things have started happening again. The whole town knows he's responsible, but the police can't do anything without proof. So Penny and her friends have no choice but to try to stop him themselves.

Except now he's after them.

Chapter One

"Penny Carson! Get inside this instant and finish your breakfast!"

Twelve-year-old Penny Carson shrugged. She knew her mother would call her again in a few minutes. Besides, she had better things to do.

She was sitting on the curb with Mac McHale. They were just killing time in that perfect part of the day, when it was cool and there was still dew on the lawns, before the June heat knocked them over.

School was out, and after a year of bells telling her where to be every minute, it suddenly seemed important to Penny to do nothing. Nothing that required any strenuous thought, and certainly nothing that involved fractions. And sitting on the curb watching Mac fry ants with his new magnifying glass definitely counted as nothing.

Mac had cleverly placed a scrap of toast with jelly as bait on the ground, and the ants kept on coming despite the fact that their comrades were going up in smoke all around them.

"They're not very smart, are they?" Penny observed.

The sound of a car door opening and slamming shut made Mac hunch his shoulders a little and focus his attention on the sizzling ants.

"Come on, Angus, let's get moving!" a voice rang out. It was Mac's mother. She was the only one Penny had ever heard call him Angus and not be beaten to a pulp.

"Where are you going?" Penny asked.

"Dentist," Mac said in his typically laconic way. Penny felt a little sorry for the dentist.

Solidly built, with a mop of reddish-brown curls and fiery green eyes, twelve-year-old Mac was the undisputed tough guy of their little group, their own private bully. He was always getting into fights, so often that his mother had become friends with the triage nurse at the emergency room.

"Angus, I mean it. Get moving!" Mrs. McHale hollered out the car window. "I don't have time for this." Mrs. McHale was a divorced mother. Mac's dad had left years ago, and Penny never saw him around. From all accounts, neither did Mac.

Mac looked at the slow-backing station wagon and shrugged in a resigned way.

"Can I borrow the magnifying glass while you're gone?" Penny asked.

Mac narrowed his eyes, considering. "Don't break it." Then he handed the silver-handled beauty over to her.

"I won't," she promised.

"Angus!" Mrs. McHale yelled, her voice rising a notch.

Mac rolled his eyes. "Gotta go. See you at the fort later."

"Right," Penny said.

She watched as Mrs. McHale's station wagon disappeared up Mockingbird Lane, passing cookie-cutter split-level and two-story colonial houses, blacktop driveways, and neatly manicured lawns. Penny turned the shiny magnifying glass over in her hand carefully. The glass was thick, and bulged out like her baby brother Sam's belly.

On the street, the ants were still circling the jelly-covered toast, blindly following one another in manic little lines. She poised the glass over the toast to catch the sun, and as the glass caught the light, she heard the low thick rumbling of a revving engine. She looked up to see a sleek red Trans Am with tinted windows rolling smoothly down Mockingbird Lane as if it had a perfect right to be there.

Penny wondered who the car belonged to. She knew what everyone drove. The last person to buy a new car had been Oren Loew's father, and it was a flashy sort of Jaguar that her mother said he was buying because of a midlife crisis. But the Trans Am was something else. For starters, it wasn't the kind of car a dad would buy, or more to the point, it wasn't the kind of car a mom would allow a dad to buy, midlife crisis or not.

She watched its careful progress down the block. With its jacked-up wheels and custom hubcaps, it was a striking contrast to all the tame-looking sedans and minivans in the driveways. It seemed to slow down as it approached, as if casing the block. Was it a robber? she wondered nervously. The Albrights' house had been robbed the previous summer when they were down at the Jersey shore, and Benji's little sister, Becky, had had her piggy bank stolen.

The car came to a gentle stop across the street in front of the Bukvics' house, the engine idling. The driver's window rolled down, and a lightly haired masculine hand languidly appeared to flick open an antique-looking silver cigarette case. The nails on the hand were thick with grease, the fingers streaked with grime. Another gritty hand appeared to remove a cigarette and tap it once on the case. And then a lighter was conjured up, a flame sparked. The hand cupped the flame. A head bent, inhaled, lit the waiting cigarette with much-practiced ease. The cigarette glowed in the darkness of the car like a burning eye.

Penny leaned forward, squinting harder, and then she caught sight of the back of that hand-and the skull tattoo. She gasped audibly and dropped the magnifying lens, which struck the curb and shattered.

She had seen a picture of him, years ago.

They had been goofing off, playing at her best friend Amy's house. Amy's mother had been on the phone downstairs, so they had taken the opportunity to sneak into Amy's older brother's room and rifle through the treasures of a fifteen-year-old boy's desk. It was there they had found the small, carefully clipped photo from a newspaper article. It had been tucked in the back of the top drawer, behind piles of rolled-up tube socks. The article had been cut away, but the caption remained:

LOCAL BOY INVOLVED IN ACCIDENT

Penny remembered that photo now, remembered the shape of the boy's head, capped with dark hair, and the thin, worn jean jacket he had been wearing. She remembered how his eyes had stared out at her from that photo, dark and glittering and unreadable. His hand had been curled around something at the edge of the photo, the menacing skull tattoo grinning from the back of his hand.

The same exact tattoo she was looking at right now.

Now, as his head swiveled toward the sound of the breaking magnifying glass, she knew it was him. It had to be.

Caleb Devlin.

"Penny Carson! Get in this house right now and finish your breakfast!" her mother called. "Now!"

The hand in the car flicked a finger, as if dismissing her, and Penny leaped up and ran inside.

Penny's family was already sitting at the breakfast table in the sunny yellow kitchen. Her father was studying the paper, and her mother was spooning baby food into Baby Sam's mouth, or at least trying to. Sam was spitting out every spoonful in a very determined way.

Penny slid into her seat and looked at the plate of scrambled eggs in front of her. Across the table, her brother Teddy was wolfing down his eggs. How could she even think of eating at a time like this? She had just seen Caleb Devlin!

"Teddy!" she hissed.

Teddy looked up sleepily from the open comic book he was reading and stared at her through brown eyes framed by thick glasses. His mousy bowl-cut hair jutted out comically in all directions, tousled from sleep.

"Guess who I just saw?"

"Who?"

"Caleb Devlin!"

Teddy's jaw dropped, revealing a mouthful of scrambled eggs.

"Teddy, close your mouth," her mother said.

His mouth snapped shut like a turtle's, and his face went a little pale. Teddy, at ten, was small for his age, and anxious. "For real?" he mouthed silently.

Penny, whose heart had slowed to a steady thump-thump after the initial shock, nodded. But was she sure? It was like seeing the Loch Ness monster, or Bigfoot. You thought that snaky head in the water was a monster . . . but was it? And Caleb Devlin was worse than a monster. Worse than any vampire or mummy or creepy-crawly slimy creature.

Caleb Devlin, the legendary kid who had terrorized an entire town, had once lived down the street in a shabby-looking ranch house at the end of a long dirt driveway that led off the cul-de-sac. The house had tired reddish-brown siding the color of a hot dog left out too long in the sun. His parents still lived there, but Caleb had been gone for years now, packed off to a juvenile home.

Mr. Cat, Penny's orange tabby, meowed plaintively at the back door.

"Somebody please let the cat out," her mother said, looking at Penny.

Penny groaned.

Her pediatrician father shook himself from the paper and looked at Penny, trying to assume a stern expression. "Listen to your mother, Penny. Be a good girl or there won't be any surprises on your birthday."

Her birthday was next week and she was looking forward to it. She had requested a new bicycle-had ripped out a picture of the one she wanted and put it on her mother's tiny desk by the kitchen phone. It was hot pink, with a handlebar brake, cool orange reflectors, and a bright, shiny horn. Penny had been riding her mother's old three-speed for the past year. It was an ugly army-surplus shade of green, and the gears always got stuck in second.

Penny had a pretty good feeling that she was going to get the bike. She had certain things going for her, after all. As the oldest child and only girl, she didn't have to suffer hand-me-downs like Baby Sam eventually would. She had her own bedroom, with pink dotted-swiss curtains and a canopy bed. Penny suspected that the bike was already in the storage shed behind the house, waiting for the big day.

Mr. Cat meowed louder, his tail rising in a threatening way that said he was going to do something bad on the carpet if someone didn't let him out soon.

"Penny, it's your cat, and if I have to clean up that carpet one more time, he's going back to the pound," her mother said, shooting her a look that said she meant business.

Penny got up and walked over to the screen door, where Mr. Cat was meowing madly. The cat caught sight of Penny and purred. She knelt down and scratched him behind the ears.

"Good cat," Penny said.

She opened the screen door and he streaked out into the backyard, dissolving into the dark shadows of the woods behind the house. Despite loving Penny, Mr. Cat sometimes disappeared for days at a time before wandering home for a cuddle and a free meal. There were a lot of orange kittens in the neighborhood, and her mother said Penny should have named the cat Mr. Gigolo.

"Mom . . . ," Penny said, sliding back into her seat.

Across the table, Baby Sam spit out a chunk of baby food with a happy gurgle.

"Come on, sweetie," her mother begged desperately, waving a spoon at Baby Sam's open mouth.

"Mom... ," Penny said. The stupid baby took up every single second of her mother's attention, and lately she wondered if her mother even knew that she still lived in the house.

"What, Penny?" her mother said absently.

"What did Caleb do that got him sent away?" Penny asked.

Her parents exchanged a look.

"Gotta go, hon. See you tonight. If the answering service calls, I'm at the hospital doing rounds, so have them beep me." Her father abruptly stood up, grabbing his white lab coat. He was out the kitchen door.

"Mom?" Penny pressed.

"I honestly have no idea, Penny. He was already gone when we moved here," her mother demurred, wiping the baby's mouth with a towel. It looked disgusting, with dribbled milk and baby food.

The phone rang shrilly.

"One of you kids get that," Mrs. Carson ordered, her attention firmly fixed on Baby Sam.

Penny leaped up to get the phone. "Hello?"

She held out the cordless phone. "It's Mrs. Bukvic, Mom," Penny said. Mrs. Bukvic lived across the street and was Amy's mother.

Her mother sighed and said, "All right, bring me the phone."

Penny sat back down and pretended to pay attention to her eggs. Her mother was trying to spoon some gross-looking food into Baby Sam's mouth at the same time as she talked to Mrs. Bukvic.

"Hi, Betty Ann," her mother said in a bright sort of voice, wedging the phone between her ear and shoulder. "Yes, it's chaos here, as usual. How are things at work?" A pause and then, "You saw who? Caleb Devlin?"

Penny met Teddy's eyes across the table. It had been him after all!

The stories flashed through her mind-the ones that were whispered on playgrounds at recess, between innings at softball games, at the bus stop before school. None of the kids knew all the exact details, but legend had it that Caleb was responsible for more than one mysterious death in the neighborhood. As if by some unspoken agreement, the parents refused to discuss it.

Their mother was saying, "Really, Betty Ann, I just can't believe all that spooky stuff," her voice trailing off into a whisper as she realized that Teddy and Penny were listening. "Let me call you back later, after I put the baby down. Okay? Great. 'Bye." Their mother switched off the phone and put it on the table, looking at Teddy and Penny.

"Uh, Mom," Penny asked in a careful voice, "did Mrs. Bukvic say that Caleb was back?"

Her mother gave her a long look. "Penny, don't let your superstitions run away with you. He's just a boy."

Penny shook her head firmly. "No way, Mom. Caleb's really bad. Everyone says so." Teddy nodded in agreement. "Yeah, Mom, everybody knows that."

Her mother shook her head, her straw-colored hair, long like a teenager's, gleaming in the warm kitchen light. At thirty-two, Mrs. Carson was younger than the other moms, and she was cool, as much as a mom could be cool. The kids who had working mothers, like Mac, jostled to hang out at the Carson house after school and drink the root beer floats she made. Her mother's coolness was elevated by the fact that she sometimes played video games with them, and was pretty good at the driving ones.

"Yeah," Penny said, pressing her point. "He must have done something for them to send him away."

But her mother was already back to trying to feed Baby Sam. She elaborately flew a spoon of strained peaches toward the baby's mouth, swooping it like an airplane. "I think Caleb got into a really bad fight with some boy," she said distractedly, as if it was no big thing, as if being sent away to reform school was something that happened to kids every day.

"I knew it," Penny said, feeling vindicated.

"Penny, it was a long time ago. And he was just a young kid then. Lots of boys get into fights." She winked at Teddy. "Even you, young man."

The ghost of a smile appeared on Teddy's solemn face.

Her mother leaned forward and pushed the spoon gently against Baby Sam's lips, but he just gave her a gooey grin, mouth firmly shut. Nothing was getting past this kid.

"But, Mom, Caleb's really dangerous!" Penny said.

Her mother looked at the baby in frustration, sat back, and pushed the hair off her forehead, clearly at wit's end. "Do you remember when we were living in Philadelphia and that boy pulled a gun on us when we were doing the laundry?"

Penny nodded. They had been in the small, steamy Laundromat down the street from their third-story walk-up apartment. Her mother had been folding her father's underwear when a skinny boy with a red knit cap had held a gun to her back and demanded all her money, especially quarters. Penny had wondered if he'd wanted quarters so that he could play pinball in the pizza parlor down the block.

"Now, that was dangerous. Nothing like that happens here. That's why your dad and I decided to move here," her mother said in a reassuring voice, absently stirring the baby food in the jar. "This is the suburbs, Penny."

"But, Mom," Penny insisted.

"People get spooked by the littlest things out here because it's so safe. You have nothing to fear. It's all silly talk." Her mother expertly pushed a spoonful of baby food into Sam's mouth. The baby promptly spit it out, the chunk landing with a distinct wet splat on the tray table.

"But-" Penny said.

"Sam!" her mother cried.

"Mom!"

Her mother was frantically wiping up the baby food, a harried look on her face. "Listen, you two, people like to gossip, especially in small towns. They say bad things about other people. But that doesn't always mean they're true. You can't believe everything you hear. Mrs. Devlin is very sick, and I'll bet Caleb is just home to visit. I really don't think his family needs to hear anything like this at such a time. So I don't want to hear either of you spreading rumors about Caleb Devlin, all right?" She spoke too fast, her voice high, the way it always sounded when she was about to lose her temper.

"But even Mrs. Bukvic knows that Caleb is bad!"

Her mother sighed heavily. "Well, Mrs. Bukvic isn't your mother, and I am. Got it?" Baby Sam, sitting in his high chair, kicked his feet, diverting their mother's attention back to the task at hand.

"All right, now. Let's get your little brother fed before he wastes away to nothing," her mother said in a determined voice.

Penny thought that was pretty unlikely. Baby Sam resembled a plump pink piglet. "Come on, now, be a good baby," her mother begged. Baby Sam opened his mouth a crack, and her mother quickly shoved a spoonful of peach baby food into his mouth. "Good baby!" Mrs. Carson clapped. She turned to Penny and Teddy and hissed, "Clap, you two. We have to encourage him."

Penny and Teddy rolled their eyes and clapped, and Baby Sam, amused, smiled broadly. "Good baby!" their mother said like a cheerleader.

Baby Sam hiccuped once and then, incredibly, barfed down the front of his bib and clean duck-yellow snuggly suit, across the short tray table, and all over the front of their mother's white T-shirt, leaving a kaleidoscope of peach baby food and something that was green and smelled like old peas.

For a moment everything was quiet, and then Teddy broke the silence.

"That," he said in awe, "was really cool."
