Around her, lights started to come on in the neighbors' houses, but Teri was barely aware of them as she watched the flames advance through her home.

At last she heard her mother scream, the sound instantly lost in the roar of the blaze. She moved across the lawn to the driveway, where she looked up to see her parents' window.

Her mother was there, sitting on the ledge, swinging her legs over the windowsill.

Then she jumped, and the spread she'd wrapped herself in caught on something.

She was falling, her head striking the pavement.

Teri ran, screaming, to her mother, and knelt beside her, to take her mother's bleeding head in her arms.

Only this time her mother wasn't dead.

This time her mother was staring up at her, her eyes accusing her, her lips forming the terrible words.

"Why? Why did you do this?"

Rage rose in Teri. This wasn't the way it was supposed to be! Her mother wasn't supposed to survive at all!

Her mother was supposed to be dead!

Her fury rising inside her like a monster, she raised her fist and smashed it down into her mother's face.

And woke up, her clenched fist smashing into the pillow where only a split second earlier her mother's head had been.

She lay still for a few moments, willing the dream to release her from its grip, the pounding of her heart slowly returning to its normal pace. Slowly, reality began to creep back into her mind.

She wasn't on the driveway in San Fernando; she was in her bed at Maplecrest, and the sun outside was shining brightly, and she could hear the lapping of the surf on the beach.

Her mother was dead, and no one had found out what she had done.

She was safe.

An hour later she awoke once more, this time not from a recurrence of the dream, but because of a shout from somewhere outside the house. She got out of bed and went to the window. On the tennis court, just beyond the pool, she could see her father playing tennis.

Playing tennis with Melissa.

A brief spasm of the anger she'd felt in the dream seized her for a moment. Her father should be playing tennis with her, her, not with Melissa. That was the way it was supposed to be, the way she'd planned it. not with Melissa. That was the way it was supposed to be, the way she'd planned it.

She'd dreamed about coming home for so many years; dreamed about the immense house facing the sea, and the big room she would have, and all the other things her mother had walked away from.

And she certainly hadn't planned on sharing any of it with a half sister, especially not one who had taken her home and her father and everything else she should have had.

Her mind went back to the strange scene she'd witnessed in Melissa's room last night, and the idea that had begun to form in her head just before she'd gone to sleep.

Turning away from the window, she unlocked the bathroom door and went through to Melissa's room. She glanced around, uncertain of what she was looking for, but knowing with a deep certainty that somewhere in here there was something she could use.

She went to the little vanity that stood against the wall between two of the windows and began opening its drawers.

In the middle one she found a slim black box, and knew even before she opened it what was inside. Still, she opened the box to stare at the single strand of pearls that lay on its satin bed.

A single strand of pearls that was identical to her own.

Another wave of anger washed over her. Melissa even had the pearls, even though she was almost two years younger than she was. Closing the box, she put it back where she'd found it, then went through the rest of the vanity.

Nothing.

At last she went to the big chest on the opposite wall and began going through its drawers.

In the second drawer, hidden beneath a pile of socks, she found what she was looking for.

It was a small diary, bound in black leather, with Melissa's initials embossed in gold on its cover. Teri opened the book and quickly began scanning its pages.

All the entries in the diary seemed to be written as if they were letters to someone named D'Arcy. But if they were letters to some friend of Melissa's, why were they in a diary?

Had she given the diary itself a name?

But then as she began to read, she also began to understand.

D'Arcy, she was almost certain, didn't actually exist at all, nor was it a name she'd a.s.signed to the diary.

Rather, it seemed as if D'Arcy was someone Melissa had made up.

An imaginary friend.

Teri scanned some of the pages quickly, turning several of them at a time. Much of what she found was almost illegible, scrawled in an awkward script that looked as if a five-year-old might have done it. But from what she could decipher, it became clear that to Melissa, at least, her friend had become real: ...I wanted to thank you for coming to help me last night. Mom was real mad at me, and I don't know what I'd have done without you......I hope Mama didn't hurt you too much last night. I don't know why she was so mad, but I guess you know how she is. Did she hit you? I hate it when she does that. If she ever did it to me, I think I'd die...

Teri was still reading, trying to figure out what it all meant, when she heard the door to the hall open. She dropped the book back into the drawer and was about to shut it when she heard Cora Peterson's apologetic voice.

"Oh, I'm sorry, I thought-" And then her tone shifted as she saw it wasn't Melissa in the room at all. "Teri? Why, what are you doing in here?"

Teri's mind raced, then her fingers closed on a pair of Melissa's socks.

Turning, she smiled at the old housekeeper. "I ran out of socks," she explained, leaning on the drawer to close it. "I just came in to borrow a pair of Melissa's." She composed her features into an anxious expression. "She won't mind, will she?"

Cora's eyes, which had been fixed suspiciously on Teri, cleared. "Well, of course not," she said, clucking her tongue. "And I'll just speak to your father-it seems to me you ought to be doing some shopping. You can't keep wearing the same clothes over and over again, can you, now?"

Teri suppressed a sigh of relief and smiled gratefully at the housekeeper. "Would you?" she asked. "I just hate asking for anything. I mean, everyone's been so nice to me..."

Cora gently silenced her. "Now, you mustn't think that," she admonished. "Why, you belong here just as much as anyone else does, and you should have everything you need." The housekeeper began making up Melissa's bed, chattering along as she worked.

But Teri had stopped listening, for she was still reflecting on Cora's earlier words.

"You should have everything you need..."

And I will have, Teri thought to herself a few minutes later as she left Melissa's room and returned to her own.

I'll have everything I need, and everything I want.

CHAPTER 8.

"Look at that! Isn't it the most gorgeous skirt you've ever seen?"

Melissa gazed through the shop window at the white cotton skirt splashed with a flowered pattern in a blue that exactly matched the shade of Teri's eyes. It was at least the sixth skirt they'd seen so far that would look perfect on her half sister, and so far they hadn't even gone into any of the shops.

They'd been in the village for almost an hour, wandering from store to store, enjoying the cool shade of the huge maple trees that formed a broad canopy over the streets and sidewalks. In almost every window they'd seen something-a skirt like the one they were looking at now, or a blouse or sweater, maybe only a pair of shoes-that seemed to cry out for Teri to try it on. But Teri had so far resisted going into any of the shops.

"I can't stand to think about how much they must cost," she'd explained. "Out in California, I used to spend whole days wandering around in the mall, pretending I could afford anything I saw."

"Well, now you can," Melissa replied, grasping her half sister's hand and pulling her toward the door. "Didn't you hear what Mama said? You're supposed to be buying clothes, not just drooling over them. Now come on."

She pushed through the door to the shop. A moment later the owner, a chic-looking woman in her thirties, stood up from her chair behind a small desk toward the back of the store and strode toward them.

"Melissa!" she said. "I've been wondering when you'd come in. Your mother called and told me to let you charge whatever you want today." She winked conspiratorially. "Stretching out your birthday?"

Melissa flushed and shook her head. "It's not for me," she explained. "It's for my sister. Well, she's not really my sister. We're half sisters. This is Teri MacIver." She turned to Teri. "This is Polly Corcoran, but everyone calls her Corky."

Teri smiled and held out her hand. "I'm very pleased to meet you."

Corky Corcoran's eyes sparkled as she shook Teri's proffered hand. "Well, there certainly isn't any mistaking whose daughter you are, is there?" she asked. Her smile faded away as a sad frown creased her forehead. "I always loved your mother so much-I used to pretend I was named after her, even though it wasn't true. I-I'm so sorry about what happened."

Teri's own smile ebbed away as she cast her eyes toward the floor and managed a slight nod. "Th-Thank you," she murmured. "I still can hardly believe it. Without Daddy..." Her voice trailed off and there was an awkward moment before Corky suddenly clapped her hands together and forced her expression back into a cordial smile.

"Well, we're not here to dwell on our sorrows, are we?" she asked, wincing at the false brightness that had come into her voice, but determined not to make Teri any more uncomfortable than she already had. "Did you see something in the window you liked?"

Teri nodded. "The white skirt? The one with the blue flowers?"

Corky's smile broadened. "Perfect," she declared. "In fact I was just thinking about the very same skirt for you myself." Her eyes expertly scanned Teri's figure. "A size four?" Teri nodded, and Corky disappeared into a back room.

While Corky was gone, Teri glanced around the shop. It was set up more like a living room than a store, with only a few garments on display, and those laid casually over the backs of chairs or hanging from mannequins discreetly posed in the corners.

It was exactly the kind of shop Teri had seen before, except today she was not on the outside looking in. She felt a shiver of antic.i.p.ation as she waited for Corky to reappear with the skirt.

Five minutes later the shop's proprietor returned from the back room, her arms laden with half a dozen items. "I thought you might like to try a blouse or two with the skirt, and perhaps a sweater," she said, spreading the garments on a mahogany library table for Teri's inspection. Teri's eyes immediately went to a silk blouse whose color perfectly matched the blue flowers on the skirt, and as she picked it up, Corky nodded approvingly. "I thought you might like that." She nodded toward a changing room concealed behind a three-paneled oriental screen, and when Teri had disappeared with the skirt and blouse, turned her attention to Melissa. "What about you?" she asked. "I have some beautiful things for fall that are just your colors."

Melissa hesitated, recalling her mother's words just before they'd left the house. "Now remember, Melissa, you're not not shopping for yourself. You have all the things you need-Lord knows your father's bought you more than you ever wear anyway-and today you're shopping for Teri. And for heaven's sake," she'd added, "try not to talk Teri into all the drab things you like so much. With her coloring, she can wear all the wonderful colors that only make you look like you have the flu." Now, the words still stinging, even though she tried to tell herself her mother hadn't meant them to sound mean, she shook her head. "I-I don't think so," she murmured. shopping for yourself. You have all the things you need-Lord knows your father's bought you more than you ever wear anyway-and today you're shopping for Teri. And for heaven's sake," she'd added, "try not to talk Teri into all the drab things you like so much. With her coloring, she can wear all the wonderful colors that only make you look like you have the flu." Now, the words still stinging, even though she tried to tell herself her mother hadn't meant them to sound mean, she shook her head. "I-I don't think so," she murmured.

Before Corky could urge her any further, Teri emerged from the dressing room. "Well?" she asked Melissa. "What do you think? Is it just perfect, or what?"

Melissa gazed at her half sister, doing her best to put down the feelings of envy that rose unbidden from somewhere in the deep recesses of her mind. But when she saw the eager look in Teri's eyes, the feeling died away. It wasn't Teri's fault that clothes seemed to fit her as if they'd been made just for her. The blouse, a soft blue that seemed to turn Teri's blond hair almost flaxen, had full sleeves that were caught at the wrists with tight cuffs, and its bodice clung to Teri's bosom with just the right draping to set off her figure yet not appear too revealing. The skirt flowed down from her waist in a gentle line to a point just below her knees. Altogether it was, indeed, perfect.

"It's beautiful," Melissa murmured.

"How much is it?" Teri asked.

Corky smiled. "The skirt's only one hundred and sixty, but the blouse is a bit more."

Teri's eyes widened and she glanced nervously at Melissa. "How much more?" she asked, her voice quavering.

"Two fifty," Corky replied. "It is is silk, after all." silk, after all."

Teri's eyes, already reflecting disappointment, shifted back to Melissa. "It's too much, isn't it?" she asked, and Melissa was sure she heard a pleading note in her voice.

Melissa turned to Corky. "Can I call Mom and ask her if it's okay?"

"The phone's on my desk," she said, "But I already talked to your mother, and she said anything you wanted was fine. And if anyone knows what clothes cost these days," she added, her brows arching slightly and her voice dropping as if she were taking the girls into her confidence, "it's your mother."

"Then we'll take them," Teri declared, her expression clearing as she went back to the table and began inspecting another blouse.

Half an hour later they left the shop with two more skirts, five blouses, and a sweater neatly packed in cardboard boxes, each of them with Corky's champagne-bottle logo emblazoned on its top in gold foil.

"Let's go back to that other place," Teri suggested as they started down the street once again. "The one with the sports clothes. This stuff's all wonderful, but I still need tennis clothes and things to wear at the club during the day."

"You mean Play Things?" Melissa asked.

Teri nodded. "They had some great bathing suits in the window."

They walked a block down the street, and soon Teri was busy in the changing room, trying on bathing suits and shorts, knit shirts and cotton slacks. When she was finally done, a stack of garments lay on the counter. They had all looked perfect on her, and they all were exactly the kinds of clothes the other kids in Secret Cove were wearing. The clerk finished writing up the bill, then looked up at Teri. "Will that be all?" she asked.

Teri was about to nod, then changed her mind as she saw Melissa look longingly at a magenta jogging suit with black stripes running diagonally across the top and repeated in a vertical stripe down the legs of the pants. "Why don't you try it on?" she asked.

Melissa reddened and shook her head. "It wouldn't look right on me."

"How do you know?" Teri argued. "You can't tell anything unless you put it on." Without waiting for Melissa to reply, she turned to the clerk. "Do you have that in her size?"

The clerk surveyed Melissa doubtfully. "Well, I don't know. She's sort of an off-size. But let me take a look." A few minutes later the clerk returned from a storeroom and handed a hanger to Melissa. "Why don't you give this a try?" she suggested.

Two minutes later Melissa came out of the dressing room and stared at herself dolefully in the mirror. To her own eye the pants seemed a little too tight and the top a size too large.

And the color-the color that had looked so wonderful until she'd put it on, now seemed to give her complexion an odd, almost yellowish hue. "Oh, G.o.d," she groaned, turning away from the mirror to gaze at Teri. "Why do I even try?"

"But it looks great," Teri told her. "If we can just get the top a size smaller, it will be perfect."

"But it won't," Melissa protested. "Look at me-it makes me look like I've got some kind of disease."

"Oh, it doesn't, either," Teri declared. "Besides, remember what your mom said? You're not supposed to get anything drab."

"I'm not supposed to get anything at all," Melissa reminded her. "I already have enough clothes."

"Well, maybe you do, but they don't look right." Melissa's eyes clouded with hurt, and Teri instantly apologized. "I don't mean they look bad," she said. "But they aren't very stylish. I mean, look at the way the other kids dress-they always wear white shorts, and polo shirts, and that kind of stuff." She moved over to a table stacked high with knit shirts and began riffling through them, pulling out one in a bright lime green and another in mustard yellow. "You could wear these," she said, holding the green one up against Melissa's chest.

Melissa gazed at the shirts wistfully, comparing them in her mind with the browns and dark greens she always picked for herself. But try as she would, she simply couldn't see herself in any of the bright colors. "Try on this one," Teri told her, pushing the shirt into her hands and handing her a pair of white shorts. "And while you're changing, I'll see if they have the jogging top in a smaller size."
