"I know," Tess said, studying her profile. "That was my fault. I did bungle it a bit. It's not like me at all. I've never worked on a case like this before." She held out a hand to Sophie, who turned and looked at it. "Let's try to work together, try to do something good for these children-okay?"

Sophie nodded and shook her hand. "Okay," she said. "Okay, I'll give it my best shot."

Mrs. Stiles's house, her life, and a large part of Sophie's past had already been packed away. There were several crates in the hallway marked "Storage," and a host of cardboard boxes stacked against any available wall space. The house where Sophie had spent so many hours, laughing and plotting and dreaming with Carrie had been swept away, leaving only faint shadows and outlines to prove that it had ever been there. Even Mrs. Stiles herself had faded to the point where she was almost translucent.

When Sophie had seen her at the christening, she had been looking older and tired, but the last three years seemed to have shrunk her away almost to nothing. She was inches shorter, and her skin was papery thin and gray.

"Mrs. Stiles," Sophie said. "I just couldn't believe it when I heard. I'm so sorry."

Mrs. Stiles nodded and gestured for Sophie to sit down on the same beige velour sofa that she and Carrie had giggled on the night of the christening and countless times before that as girls. "We tried so long for Caroline, her dad and I," she said. "Everyone else was having baby after baby except me. Five years went by, then it was fifteen, and I thought it just wasn't meant to be. It wasn't in Jesus' plan, you see. When she came, I was so unprepared that I thought it was the change! She was my miracle. My gift." Mrs. Stiles's smile faded. "I don't why loving her so much wasn't enough. I don't know why she went away, why she let that...man"-she spit out the word-"ruin her life just like her father ruined mine." She coughed and gagged as if she might choke on her bitterness. "And now the lives of those poor children too. Everything that has happened to them has happened because of him. If he'd been at home like he should have been, supporting his family, Carrie wouldn't have been driving that death trap." She stopped talking abruptly and caught her breath. "I just feel so angry, all of this, all of this is his fault."

Sophie did not know quite what to say, so she said nothing and listened to the house, perfectly quiet except for the ticking of a clock.

"Where are the children?" she asked eventually.

"Upstairs," Mrs. Stiles said. "I told them to wait there and not make a peep until we were ready for them. They're no trouble, you know, as long as they know who's boss. They packed all their bits. They don't have too much with them, just a big suitcase between them-almost everything is still in Carrie's house-there's been no one really to sort it out. The neighbor's been good, keeping an eye on it-but there's so much that needs doing. I didn't think I would have to do it-" She reached out and took Sophie's hand in hers. Her skin felt dry and rough.

"I just can't do it," she said, and Sophie knew she was talking about the children.

"I know," she said.

"Well," Mrs. Stiles said with a sharp edge to her voice. "I always said to Carrie that you were the sensible one. And now look."

Sophie sat back in her chair and withdrew her fingers from Mrs. Stiles's hand. She had expected her to be upset but not angry.

"Ms. Andrew, call the girls down, will you?" Mrs. Stiles said.

Sophie swallowed hard and counted the last seconds of her foreseeable freedom as footsteps thundered down the stairs, the living room door flew open, and a small child flung herself into Sophie's lap with some considerable impetus, winding her momentarily.

"Goodness, child, slow down," Mrs. Stiles said, but the child in question ignored her and flung her arms around Sophie's neck. At first Sophie thought it was Bella, but then she saw Bella standing in the doorway and realized that this must be Izzy in her lap, resplendent in a lilac fairy costume complete with wings and a glittery net skirt.

The child kissed Sophie wetly on the cheek and patted her head fondly. "My mommy's car is broken," she said. "There was a bang and a man in a van, and it's broken now, it's in the garage. I don't like cars, do I? Have you got any chocolate birthday cake? Are you three or seven today?"

Sophie looked at her. "Um," she said.

Bella crossed the room and gave Izzy a sisterly look of disapproval. Sophie thought she saw a trace of Carrie in the expression, just a trace among the dark good looks Bella must have inherited from their father. Izzy clearly resembled her mother, who was fair-skinned and whose light brown hair was almost a honey blond.

"Shut up, Izzy," Bella said. "She's much older than seven, idiot." Bella held out her hand, and Sophie took it and shook it, still struggling to find something appropriate to say.

"I like your boots," Bella said. "I like pink, it's my favorite color."

Sophie smiled at the girls. "Me too," she said.

"Me too!" shouted Izzy, causing Mrs. Stiles to wince. A passion for chocolate and an eye for shoes. Maybe she did have something in common with the girls after all. A shame then, Sophie thought as she smiled fixedly at the girls, that she felt as if she were having her very life pulled inside out by an overwhelming vacuum of fear.

"Right then," Tess said, gathering up the reams of papers she had laid out across Sophie's blond ash coffee table. "I'll be off. See you tomorrow, girls."

"Bye, Tess," both girls sang absently, mesmerized by something Tess had found for them to watch on TV involving huge multicolored puppets and a lot of shouting.

"Off?" Sophie said anxiously. "Off where?" They had been back at her place for less than two hours, in which Sophie had seen a small, quite neat flat transformed into a jumble sale of dirty, multicolored clothes. Tess had suggested that, when she had time, Sophie might clear the girls a drawer, but in the meantime, she helped them sort out what was clean and what wasn't, refolded what she could neatly into the suitcase, and loaded the rest into Sophie's washing machine. Sophie, who was more of a dry-clean-only sort of girl, rarely used her washing machine. When it had juddered and shaken its way into a final spin, Sophie had jumped out of her skin.

"Where do you have to go now?" Sophie repeated her anxious question.

"Oh, you know, work," Tess said. "It's almost four, Sophie. I have to get all this signed, sealed, and, er, delivered tonight."

"But so soon? I mean, do you think I'm ready?"

Tess smiled at her and dumped the sheaf of papers into her sequined patchwork tote bag seemingly without the vaguest concern over tears or dog-ears.

"You said before in the cab that you'd help me, that I wasn't alone!" Sophie said tremulously.

"I know," Tess said. "And I meant it, but I can't move in. If I could, we wouldn't have this problem. There are other people out there who need me, plus a load of paperwork that needs doing. The law makes a special provision for cases like yours. I'll be at a night court until late arranging your residency order." Tess looked around the flat, the second floor of a converted Georgian town house, and tucked one chin into another as she smiled at Sophie. "Look, you have nice flat. Obviously a little too small for an adult and two children, what with only one bedroom and no garden, but on the whole I'm satisfied. It will do for now. And the girls seem to have settled in okay. I think they're getting used to moving around, poor mites. You'll be fine."

Sophie looked at the girls. What Tess said was right-she had expected them to be Dickensian waifs, thin and pale and red-eyed. But they seemed to be handling this with much more presence of mind that she was, and they had been very manageable since they left Mrs. Stiles's. It must be, Sophie thought, because they don't really understand what's happening. Perhaps they are too young to really feel the loss and upheaval.

Sophie had thought there would be tears when they said good-bye to their grandmother, but the girls hadn't seemed too sorry to leave her. Mrs. Stiles had told them she would see them soon and to keep their chins up, and both of them did, literally in Izzy's case, causing her to walk into the gatepost at the bottom of the garden path. If there had been any hint of tears, it might have been from Mrs. Stiles, who had pressed her lips so firmly together as she watched the girls leave that her mouth had turned pale and bloodless. She'd shut the door before they had closed the garden gate behind them.

Miraculously, Sophie had seen a black cab turn in to the street and had stepped out to the curb to hail it, but just as the cabbie caught her eye, Tess had pulled her back onto the pavement and waved the driver on; he'd sworn through the glass at the pair of them and shaken his head with irritation.

"What's the problem?" Sophie had asked Tess. "Was it money? Because I was going to pay-my place is a long walk from here, you know. I didn't think these two could walk that far. Short legs and all that." Sophie had looked at the battered and brimming suitcase at her feet. "And this is heavy."

Tess had shaken her head.

"Oh look, girls!" she'd exclaimed. "Ants!" Astonishingly, the discovery had seemed to delight both girls, who'd crouched over the crack in the pavement and watched the busy insects track and bustle across the stone slab. After a moment Bella had started to give the ants tiny tinny voices, commenting on their every movement, making Izzy chuckle, her small shoulders shaking.

Sophie had raised a questioning eyebrow at Tess. "I didn't think we'd be stopping for a natural history lesson," she'd said.

Tess had taken a step closer to Sophie and lowered her voice. "I told you Izzy is still a bit iffy about cars," she'd said. "After the crash."

"Oh." Sophie had forgotten that piece of information. "When you say iffy, what do you mean exactly-she can't go in cabs at all? Because I didn't think she'd know, you know, that her mum had been killed in a car crash. I didn't think she really got that her mum was killed. I mean, she seems pretty happy."

Tess had chewed her lip. "I obviously didn't make myself clear," she'd begun ominously. "Izzy was in the car when Carrie was killed. A van going fifty hit them on the driver's side at an intersection. Izzy was in a car seat. She was protected. Frightened and alone for almost ten minutes until help came, but physically unhurt. Carrie's seat belt was faulty. Apparently she knew it was, she just hadn't got around to getting it fixed. She was killed outright. Thrown from the car. So Izzy's a bit iffy about getting in cars, including cabs, I'm afraid."

Sophie had looked down the length of the tree-lined road that she and Carrie had walked along so many times together talking incessantly-making plans, creating dreams for themselves. Carrie was going to be a painter, of course, and a fashion designer. She was going to live right by the sea in a tower and marry a fisherman. Sophie was going to become a vet and run a cat sanctuary. She was going to marry Jason Donovan. It was funny how Carrie's dream never changed and how she had made it more or less come true. Sophie's plans changed from year to year: different occupation, different celebrity husband, until her dreams and fantasies had faded away into real solid ambition, into her life as it stood now. Even now, even knowing exactly what she wanted and exactly where she was going, Sophie assumed she had enough time left on the earth to make it happen. But Carrie had never planned to be thrown from a car and killed taking her daughter to nursery school. Neither one of them had ever dreamed she'd die. Not now, not ever.

"Does she understand what happened then?" Sophie had asked. To be perfectly honest, Sophie had no idea what three-year-olds could or could not understand. If she'd ever thought about it before that day, and she never had, she would have guessed they had about the same amount of reasoning power as the average dog-maybe a collie or a German shepherd-and much less than a cat.

Tess had shrugged. "She understands that it was very frightening and that she hasn't seen her mummy since. I'm not sure what else she understands. I haven't really had time to talk to either of them properly. I don't think anyone has. Like I mentioned before, I've got both girls down for counseling, but, well, there's a waiting list." For a second Sophie had not known what to say, and she'd felt the weight of the children's terrible loss nudging at her edges. She'd blinked hard and chased the feeling away. There was no time for that now, she'd told herself. Right now she needed to stay focused on the project at hand.

"There's a bus stop at the end of the road," Sophie had said at last, hefting the suitcase off the ground. "We'll get the bus."

"Anyway," Tess said as she checked her cell phone. "I'll pop back in the morning, see how you're getting on, okay?" Sophie nodded and fingered the twenty-two-karat white gold chain around her neck until she caught the half-carat diamond pendant it held between her fingers. It had been her present to herself after her last promotion, material proof that she was making it. Sophie liked to be able to measure her progress through life with things she could see and feel. Hence her shoes and her precious jewelry collection, which was small but expensive. They were more than just objects-they were markers of specific times or achievements. They were three-dimensional memories.

"Right, okay," she said to Tess, desperately trying to fight down the wave of panic that was surging in her chest. "What do I do with them?" she hissed. "They're okay now, but what if they start crying or something?"

"Then give them a hug," Tess told her.

"A hug." Sophie looked dubious.

"But in the meantime, just give them some tea," Tess added, looking at her watch.

"Tea? Really?" Sophie said. "Okay. If you say so."

Tess gave her a slightly quizzical look as Sophie walked her downstairs and opened the main entrance door. As Tess walked out, Sophie's cat, Artemis, walked in, shouldering her way past Sophie's legs without the faintest of greetings. Sophie wasn't offended, that was just Artemis. It took her a long time to establish complete trust with a human. Sophie wasn't sure exactly how long, but it was definitely longer than the three years since Sophie had rescued Artemis from the cat home where she had been the least popular and most solitary inmate. For some reason, though, Sophie had been drawn to her and had slavishly adored her from the moment she brought her home. An emotion that was definitely not reciprocated by the cat. Artemis merely tolerated her.

Normally when she came in this way, she'd shoot straight up the stairs and into the kitchen, looking for her dinner. But today she stopped at the foot of the stairs and stared up them.

"Ah yes," Sophie said to the cat. "There's something I've got to tell you." She scooped Artemis up in her arms. The cat went rigid in her embrace and tightened her claws on Sophie's sleeves just enough to make holding her uncomfortable. Sophie took this as a good sign. If Artemis had been really pissed off, she would have drawn blood and twisted her way to an escape by now, just as she used to when Sophie first brought her home from the shelter. "The thing is, Artemis, we've got guests. Children. Now, I know you hate noise and mess and people invading your space and touching all your things, but it's only for a week, okay? So try to be nice. At least try not to be violent. I mean, you never know, you might really like them, couple of kids to play with."

Artemis did not look convinced, and neither was Sophie. After all, the only other creatures that Artemis had ever happily played with to date were a disemboweled mouse and a not quite dead starling chick. Still, no need to tell the girls that.

Sophie carried a horrified Artemis into the living room and presented her to the children. "Bella, Izzy," she said. "This is my cat, Artemis-"

"Catty!" Izzy shrieked with delight and bounded over the arm of the cream leather sofa in one fluid moment. Artemis shot out of Sophie's arms with a yowl and disappeared into the bedroom.

"Um, that was my cat, Artemis," Sophie said. "She's a bit..." Sophie was going to say "antisocial" but thought better of it. "She's a bit shy. I got her from a cat shelter. Her last owners weren't very kind to her, so people aren't her favorite thing. She'd been at the shelter for nearly a year when I got her. No one else wanted her because she was so...shy. We get along okay, though. I love her, and she ignores me. It works pretty well."

Izzy had dropped to the floor and was peering under the sofa. "Catty? Catty where are you?" she inquired. "Come back, Catty. Izzy's going to cuddle you up!"

"The thing is, Izzy," Sophie said to the child's bottom, "It's probably best that while you're staying here you leave her alone. Okay?"

"Okay," Izzy said cheerfully. "Catteeeeeeeeeeeeeeeeee? Whereareyooooooooo?" She peeped around the living room door and looked each way down the short hallway before advancing toward the bedroom. Evidently, Izzy's definition of okay was different from Sophie's. Well, looking for Artemis would keep her occupied for a few minutes, Sophie reasoned. There was no way Izzy would find Artemis on top of the wardrobe, her favorite hiding place anyway, so they would both probably be quite safe for the time being.

"So," Sophie said to Bella, who remained sitting, her hands primly on her knees. "Tess said to give you tea. How do you like it? Milk, sugar? Earl Grey? I think I've got Darjeeling somewhere..." Bella blinked her brown eyes at her from under her thick black and slightly too long bangs.

"I think she meant food tea, Aunty Sophie," she said slowly, as if English wasn't Sophie's first language. "Like dinner?"

Sophie sat down on the sofa next to her. "Obviously I knew that!" she lied. "I was joking! Ha-ha. Get it?"

Bella shook her head. "No," she said deadpan. "It wasn't funny."

For a moment Sophie was reminded of a film she'd once seen where the world was taken over by evil aliens disguised at kids. She forced the thought to the back of her mind. She was the adult, they were the children. She was in charge. It wasn't like, for example, The Omen, at all, nope, not in any way. These were Carrie's children. Not the Antichrist's-although Sophie really hardly knew Louis, so she couldn't rule that out entirely.

"So tea!" She said with renewed vigor. "Let's go and see what's in the fridge, shall we, Bella?"

There was nothing in the fridge except for half a pint of skim milk, three shriveled spring onions, low-fat margarine, and two Marks & Spencer low-fat ready meals, Thai green chicken curry and seafood pasta. They would have to do.

Sophie took the two meals out of the fridge, forked their film coverings with enthusiastic aggression, and shoved them in the microwave. Bella watched Sophie display the extent of her culinary skills, her brown eyes just about reaching over the rim of the counter.

"What is that?" she asked Sophie.

"It's seafood pasta and chicken curry," Sophie said. "Yum yum."

Bella said nothing but eyed the microwave warily for a moment. She looked around the narrow galley kitchen. "Your kitchen is very small," she said. "Where do you eat?" It was a valid question.

"On the sofa usually," Sophie said. "Is that okay?"

Bella looked skeptical. "Well, it's okay for me, but..."

"Excellent, that's settled then," Sophie said. Just at the moment that the microwave beeped there was a crash from the bedroom and the screech of a furious cat, followed closely by the cries of a distraught child.

Sophie and Bella ran into the bedroom. Izzy was lying sprawled on Sophie's bed, with Sophie's old-style umbrella in one hand and half of one leg trapped underneath Sophie's empty and fortunately lightweight suitcase.

"Catty!" Izzy sobbed, waving the umbrella wildly at the open window. "Catty, come back!"

Sophie looked out the small window that she always left open for Artemis to come and go as she pleased. She was sure that leaving the window open pretty much negated her insurance policy, but she couldn't bear the thought of cooping Artemis up in the flat when she'd been imprisoned in the shelter for so long. Artemis had certainly been glad of the escape route on this occasion. She must have scooted across the little balcony onto the downstairs extension roof, and off into the evening in double-quick time. Sophie didn't think she'd be coming back anytime soon, and she felt a pang of helpless anxiety. She didn't know why she worried about Artemis. Artemis was a pretty tough cat.

Bella climbed onto the bed and pushed the suitcase onto the floor with a thud. She put her arm around Izzy and pulled her into a sitting position. Kissing the younger girl's light brown hair, Bella patted her firmly on the back three times. "There. There. There," she said with each pat. Sophie wasn't sure what she was supposed to do. Perhaps she was supposed to hug Izzy and do a bit of patting too, but she didn't quite know how to go about the whole hugging and patting thing, so she left it to Bella and sat on the edge of the bed instead.

"What happened, Izzy?" Sophie asked her.

"Catty was stuck, I was helping Catty, like when Bob the Builder helped Pilchard," Izzy sobbed. "But she ran away! I wanted to cuddle her up!"

Sophie guessed that Izzy had spotted Artemis on top of the wardrobe and, unable to reach her, had climbed onto the bed with Sophie's hook-handled umbrella, which had been propped in the corner of the bedroom, and tried to hook the cat down. An event that would have horrified poor old Artemis. Still, it proved that Izzy had at least as much reasoning power as a border collie after all.

Sophie ventured out a hand to pat Izzy's knee, then quickly withdrew it. "Don't worry," she said. "Artemis will be back when she wants to be. Probably best not to cuddle her up next time she comes home. She's not a big fan of the cuddle as a concept."

"Okay." Izzy sniffed. Sophie wasn't sure whether or not to take that as agreement.

The microwave beeped again. "Tea's ready!" Sophie said brightly, and both girls did look more cheerful. They must really be hungry, poor kids, Sophie thought.

In preparation, Sophie positioned them both on the sofa and gave each of them a paper towel to prevent spillage. She gave them each a fork and a knife, and looked through her practically medieval five television channels for something they could watch, settling in the end for a talk show, Richard & Judy.

"Oooh, a knife," Izzy said, inspecting the implement she had been handed as if it were a lethal weapon.

In the kitchen, Sophie tipped out each ready meal onto a separate plate. She thought for a moment and then tipped the seafood pasta onto the Thai green curry plate and mixed it around until it was slightly lighter shade of green. Then she split the mixture in two and slid one half back onto the second plate. That way there'd be no arguments about who was having what, she thought, feeling pleased with herself. Foresight, that was what she had displayed there. Foresight. A key problem-solving skill was to solve the problem before it even occurred.

She took the plates to the living room, where Izzy was endeavoring to cut open the sofa with the blunt serrated edge of her knife.

"Um." Sophie made especially sure that she did not raise her voice. "Izzy, don't do that darling, okay?" she asked her, wondering if the exorbitant cost of the sofa would mean anything to Izzy. Probably not.

"Okay!" Izzy said, sawing away regardless.

"Here's tea now anyway," Sophie said. She handed the girls a plate each. "Okay, enjoy, I've just got to make a couple of quick calls, so I'll be back in a minute, okay?"

"Okay!" Izzy said, transferring her sawing attentions to the food.

Bella looked at her food suspiciously and poked it with her fork. "Okay," she said with much less enthusiasm.

Sophie picked up the phone in her bedroom and called Cal first.

"How's it going?" he asked her, unable to keep the amusement out of his voice.

"Fine, it's fine actually," Sophie said, wondering if her voice sounded as high on the other end of the phone line as it did in her head. She made a conscious effort to lower it a half octave. "I've given them their tea, then I expect they'll go to bed after." she said confidently.

"What, at five o'clock?" Cal did not sound so confident.

"Never mind that," Sophie said, brushing his doubt aside. "Did the contracts from the bank come through okay?" Cal confirmed that they had. He gave her a rundown of the day's events and the inside scoop on how Lisa had handled all of her new duties. "Pretty well, actually," Cal said. "She hasn't cried for the whole afternoon. Barely even a sniffle. Well, maybe the occasional sob-but mainly I think you being out of the office is good for her. She's too scared of me to mess me around."
