Four teens fight to outsmart a killer who intends to avenge a young boy’s death in this suspenseful thriller that inspired the classic horror film.


After a party, four teens are in a hit-and-run accident that results in a young boy’s death. Unable to deal with the consequences, they leave the body behind and make an anonymous phone call to the police, tipping them off.

The group makes a secret pact to bury the memory of that night and never speak of it again, but when one of the girls receives a note that reads “I know what you did last summer,” their dark lie is unearthed. With twists and turns at every corner, they’ll have to fight to stay steps ahead of a killer determined to make them pay.

With slowly growing horror she stared at the letter, at the one black sentence that peered up at her from the smudged paper.…

For Ginger Palmer


The note was there, lying beside her plate when she came down to breakfast. Later, when she thought back, Julie would remember it. Small. Plain. Her name and address hand-lettered in stark black print across the front of the envelope.

At the time, however, she had eyes only for the other letter, long and white and official. Hurriedly, she picked this up and paused, glancing across the table at her mother, who had just come in from the kitchen.

“It’s here,” Julie said.

“Well, aren’t you going to open it?” Mrs. James set the coffeepot down on its hot plate. “You’ve been waiting for this long enough. I would think you’d have had it open before you even sat down.”

“I guess I’m scared,” Julie admitted. She slipped her forefinger under the corner of the flap. “Okay. Here goes.”

Running her finger the length of the envelope, she drew out the folded sheet of stationery and smoothed it flat on the table.

“Dear Ms. James,” she read aloud. “I am pleased to inform you that you have been accepted—”

“Oh, honey!” Her mother gave a little gasp of delight. “How wonderful!”

“Accepted!” Julie repeated. “Mom, can you believe it? I’m accepted! I’m going to Smith!”

Mrs. James came around the table and gave her daughter a warm hug.

“I’m so proud of you, Julie, and your dad certainly would be too. If only he could have lived to have known about it, but—oh, there’s no sense in looking backward.” Her eyes were suspiciously bright. “Maybe he does know. I like to think so. And if not, I’m proud enough for the both of us.”

“I can’t believe it,” Julie said. “I honestly can’t. When I took those tests, I felt as though I was missing so many questions. I guess I knew more than I thought I did.”

“It’s your senior year that’s made this possible,” her mother said. “I’ve never seen such a change in anybody as in you this past year. The way you’ve buckled down and studied—you’ve been a completely different person. And, I’ll admit this now, it’s worried me a little.”

“Worried you?” Julie exclaimed in surprise. “I thought you always dreamed of my going to the same college you did. Last year you were on me all the time about being out too much and never cracking a book and spending half my life at cheerleading practice.”

“I know. It’s just that I never expected you to do such an about-face. I can almost pinpoint the day it happened. It was just about the time you broke up with Ray.”

“Mom, I’ve told you—” Julie tried to keep her voice light despite the sudden shock of cold that hit her stomach. “Ray and I didn’t exactly break up. We just decided we were seeing too much of each other and we’d slow it down for a while. Then he left home and took off for the coast, and that took care of that.”

“But to give up dating so completely—”

“I haven’t,” Julie said impatiently. “I still go out some. In fact, Bud’s coming over tonight. That’s a date.”

“Yes, there’s Bud. But that’s only been recently, and it’s not the same. He’s older, more serious about everything. Of course, I’m happy and proud that you’ve put in enough work to get accepted by a good East Coast college, but I wish you’d been able to balance it better. Somehow I have the feeling that you’ve missed a lot of the fun of your senior year.”

“Well, you can’t have it all,” Julie said. Her voice sounded high and sharp, even to her own ears. The cold feeling in her stomach was spreading higher, up where it touched her heart. She shoved back her chair and got up. “I’m going up to my room. I’ve got to find my history notes.”

“But you haven’t eaten,” Mrs. James exclaimed, gesturing toward the plate of scrambled eggs and toast, still untouched on the table.

“I’m sorry,” Julie said. “I-I guess I’m too excited.”

She could feel her mother’s worried gaze upon her as she left the table. Even after she was out of eyesight, the worry stayed with her as she climbed the stairs and went down the hall to her room.

Mom knows too much, she thought. She has this funny way of knowing more than you ever tell her. “I’ve never seen such a change in anybody,” her mother had said. “I can almost pinpoint the day…”

But you can’t, Julie told her silently. Not really. And you shouldn’t try. Please, Mom, you shouldn’t ever try.

She entered her bedroom and shoved the door shut. It closed with a sharp click, and her mother was left behind, back down in the breakfast room with the uneaten eggs and the coffeepot. The room closed protectively around her, a perfect room for a teenage girl who was pretty and loved and happy with herself, a girl who had never had a problem.

Her mother had had the room decorated for her a little over a year ago, on her sixteenth birthday. “We’ll have it done in any color you want,” she had said. “You can choose.”

“Pink,” Julie had said immediately. It was her favorite color, the one she wore most often, even though she had red hair.

There was a pale pink T-shirt in the farthest corner of her closet, buried behind the other clothes. It had been new that night last summer. “You look like a rosebud with freckles,” Ray had teased her. The shirt looked great on her, but she had never worn it after that night. She would have given it away, if she had not been afraid that her mother might remember it sometime and ask what had become of it.

Now she seated herself on the end of her bed, drawing deep, slow breaths while the cold within her faded and her heart grew still.

This is dumb, Julie told herself firmly. It’s been almost a year since the thing happened. It’s over and done with, and I swore to myself I’d never think about it again. If I let myself get this uptight over some innocent little comment of Mom’s, I’ll wind up right back where I started, an absolute basket case.

Across from her in the oval mirror over the bureau another Julie looked back at her, pale and unsmiling. I have changed, she thought with mild surprise. The girl in the mirror bore little resemblance to last year’s Julie, bubbly, bouncy, spark plug of the pep squad, the cheerleader with the smallest size and the biggest yell. This girl had shadows behind her eyes and a tightness about the mouth.

You’re going to Smith, Julie told herself. Just keep that in mind, will you? You’re getting out of here in only a couple of months. You won’t be going to the university, you’ll be going east, away from this town, and the road, and the picnic area above it. You won’t be running into Ray’s mother at the drugstore. You won’t see Barry on campus or Helen on television. You’ll be out—free! A new place, new people, new things to do and think about, a whole new set of things to remember.

She felt steadier now. Her breathing was slow again and even. She picked up the letter from Smith, which she had dropped on the bed beside her, and looked again at her name, neatly typed, on the official-looking envelope. She would take it to school with her, she decided; there were people there she could show it to. Not to any other students, especially—there wasn’t anyone she was that close to this year—but Mr. Price, her English teacher, would be happy for her, and Mrs. Busby, who taught American Studies.

And tonight when Bud came over she would show it to him. He’d be impressed, and sorry, maybe, because she would be going away. Bud had been calling so often recently that it was possible he was getting more serious than he should be. It would be good for him to realize that this relationship wasn’t going to go anywhere, that it was just for now and in the fall she would be somewhere else.

There was a rap on the bedroom door.

“Julie?” her mother asked. “Are you keeping track of time, dear?”

“Yes. No…I guess I wasn’t.” Julie got up off the bed and opened the door. “I was just sitting here, gloating over the acceptance. Honestly, I’d just about given up hoping. It’s been so long since I applied.”

“I know,” Mrs. James said sympathetically. “And I didn’t mean to take the wind out of your sails by criticizing. I know how hard you’ve been working, and I’ve just been afraid you were overdoing it. I’m glad that now you can relax and enjoy your summer.”

“I’m glad too,” Julie said.

She put her arms around her mother and gave her an impulsive hug. Her mother’s arms came back around her, surprised and glad.

I ought to hug her more often, Julie thought. I don’t deserve to have somebody like this for a mother. I love her so much, and I’m all she has since Daddy died. Now I’ll be going away and she’ll be alone, and still she’s happy for me.

“Are you sure you’ll be okay?” she asked against her mother’s soft cheek. “Can you get along, do you think, with me so far away?”

“Oh, I think so,” Mrs. James said with a catch in her voice that was supposed to pass for laughter. “I made out all right before you were born, didn’t I? I’ll keep busy. I’ve been thinking that maybe I’ll go back to work full time.”

“Would you like that?” Julie asked. Her mother had been a home economics teacher before her marriage, and since her husband’s death eight years ago, she had been working as a substitute.

“I think I would. It would be nice to have my own class again. With you out of the nest there won’t be anyone to need me at home, so it’s time to be needed somewhere else.”

“I did lose track of time,” Julie said apologetically. “I’d better get going.”

Her mother glanced at her watch. “You are late. Would you like for me to drive you?”

“That’s all right,” Julie told her. “I haven’t been late all year, so it won’t kill me to get a late slip today. And maybe I won’t. Mr. Price is a pretty nice guy about things like that.”

She gathered up her books and history notes from the bedside table. Downstairs she paused long enough to rummage in the coin bowl on the sideboard for enough money to buy a Coke later.

“I’ll see you after school,” she said. “Bud’s not picking me up till around eight, so there’s no reason we have to eat early. Are you going out anyplace?”

“I don’t have any plans,” Mrs. James said. “Wait a minute, honey. You didn’t get your letter.”

“Yes, I did. It’s here in my notebook.”

“No, I mean the other one.” Her mother leaned across the table to pick up the second envelope, half-concealed by the edge of the egg plate. “There were two pieces of mail for you this morning. Not that this could possibly be as exciting as the first one.”

“It’s the size of a party invitation, though I don’t know who would be inviting me to a party.” Julie took the small envelope from her mother’s hand. “That’s funny. It has big block printing and no return address.”

She tore the envelope open and removed a folded sheet of lined paper.

“Who is it from?” her mother called back over her shoulder as she carried the breakfast dishes into the kitchen. “Anybody I’ve ever heard of?”

“No,” Julie said. “Nobody you know.”

With slowly growing horror she stared at the letter, at the one black sentence that peered up at her from the smudged paper.

I’m going to be sick, she thought. Her legs felt weak, and she reached out and caught hold of the edge of the table to steady herself.

It’s a dream, she told herself hopefully. I’m not really awake and standing here in the dining room at all. I’m lying in bed upstairs, asleep, and this is only a nightmare like the ones I used to have back in the beginning. I’ll close my eyes, and when I open them I will wake up. It will be gone…the paper will be gone. It will never have been.

So she closed her eyes, and when she opened them again the paper was still there in her hand with one short sentence printed on it:



It was almost dusk when Barry Cox pulled out of the parking area behind the frat house and drove through the campus and then north on Madison to the Four Seasons Apartments.

It was a familiar drive; in fact, he sometimes said jokingly to his frat brothers that the car knew it so well that it could drive there by itself.

“Sure it won’t get confused?” they joked back. “It knows the way to a couple of other pads too.”

“It keeps them straight,” Barry told them smugly. “It’s got a GPS.”

It was true that Helen wasn’t the only girl Barry went out with, though he was pretty sure that he was the only guy she was seeing. Crazy too, because living where she did, in an apartment complex full of singles, and looking like a swimsuit model, and holding her showy job—well, there were bound to be plenty of werewolves howling under her window.

That was one reason he continued seeing her on a regular basis. He hadn’t planned to once high school was over. A college man had a wide territory, and there were some pretty hot girls on the University campus who would be easy to hook up with, no strings attached. Then, when Helen had been handed that job as Future Star, it had changed things. A guy would have to be nuts to throw over the Channel Five Future Star.

Now as he pulled into the Four Seasons parking lot, he grinned to himself. Helen was doing all right for an eighteen-year-old who hadn’t even finished high school. His mother had gone through the ceiling when she learned about Helen’s dropping out at the end of her junior year. “It proves what I’ve said from the beginning,” she had told him. “A person is the result of her background. That girl isn’t your kind, Barry; I don’t understand how you ever started dating her.”

Which, of course, was part of the reason—he knew it would bug his mother. And then there were her looks. Helen was beauty queen material, and the fact was already beginning to pay off for her. Not many girls her age had their ownapartments without even having to split the cost with a roommate. Helen’s older sister, Elsa, was still living at home, stashing away half her earnings as a cashier in a department store, hoping that maybe someday, in a year or so, she might be able to make the break and get her own little hole-in-the-wall. And here was Helen with her own car, trendy clothes, anything she wanted, and not a worry in the world.

So what had she been so upset about on the phone? That call had surprised him. Helen wasn’t like a lot of girls, always calling their boyfriends. She seldom even texted him unless there was a definite reason.

This time she hadn’t given one.

“I’ve got to see you,” she had said. “It’s important. Can you come over later when I get off work?”

“Tonight? Heller, we were just out last night. You know thisweek is off limits. I’ve got finals to study for.”

“I told you, it’s important.” There had been an edge to her voice, something that didn’t happen often with Helen. Usually if he told her something, she accepted it without question. “I wouldn’t call you like this if it wasn’t. You know that.”

“Can’t you tell me what it’s about?”

“No.” She had left it at that. Just a flat no. He was intrigued in spite of himself. He did have exams to study for, and he had a date later for coffee with Ashley Something-or-other from the Tri-Delt house, but nothing that couldn’t be shoved over a little.

“Well, if we make it early,” he said. “Right after dinner.”

“That’s fine. The earlier the better.” She hadn’t asked him to eat with her, and he was fine with that. Those domestic evenings with Helen running around serving pot roast by candlelight were rough to handle. He knew what she was aiming for, and it wasn’t what he was aiming for, and the whole game was making him jittery.

“I’m calling from the studio,” she said. “I’ve got a webcast to do in a couple of minutes. I’ll see you around seven then, okay?”

“Okay,” Barry had said.

The conversation had left him curious. So curious, in fact, that he hadn’t bothered to go to the dining hall for dinner. He had just stopped at a Wendy’s and picked up a couple of burgers and a Frosty. Now here it was, barely past six-thirty, and he was climbing out of his car and starting up the walk that led past the pool to the steps to the second-level apartments.

The pool and the area around it were crowded. The spring evening was still pretty cool, but the pool itself was heated, and there were some polar bear types splashing around and plenty of pretty girls sitting high and dry in deck chairs, taking the first opportunity of the season to show off their figures in bikinis.

For a moment he stopped, just enjoying the view, a little surprised that Helen wasn’t among them. She had a figure that was better than the best of them, and she wasn’t one who minded displaying it.

“Hi,” called one of the girls, a shapely little brunette in a red and white halter and short shorts. “Are you looking for an apartment? There’s a vacancy on the second floor.”

“Nope,” Barry replied, giving her a measuring glance. “Not this year, anyway.”

Actually, he would have given anything to be able to live in a place like this, but it wasn’t his mother’s idea of something the old man should finance. He was damned lucky, when it came to that, just to have gotten into a frat house.

He went on around the pool and up the stairs, pausing to glance back at the brunette, who had turned sideways in her chair and was still watching him. Then he went on down the upper deck and rapped on the door of Helen’s apartment.

He had to wait a few minutes for his knock to be answered, something that seldom happened at Helen’s. Then the door opened and she was standing before him. She looked good, as always. Her honey-colored hair was pulled back from her face and held in place with a gold band, and her violet eyes were carefully shadowed and outlined to make them even lovelier. She was wearing pale blue pants and a silk blouse with a chunky crystal necklace at the throat; evidently she had not changed clothes since coming back from the studio.

“Good,” she said. “You’re early. I was hoping you might be.”
