Roz turned her pencil in her fingers.

"Why not?"

"I don't have to give a reason."

"It would be polite," said Roz in the same even tone.

"I've invested a great deal of time, energy, and affection in you. I thought we were friends."

Olive's lip curled.

"Friends," she hissed scathingly.

"We're not friends. You're Miss Wonderful making money out of doing her Lady Muck bit and I'm the poor sap who's being exploited."

She splayed her hands across the table top and tried to get up.

"I don't want you to write your book."

"Because you'd rather be treated with awe in here than laughed at outside." Roz shook her head.

"You're a fool, Olive.

And a coward as well. I thought you had more guts."

Olive pursed her fat lips as she struggled to rise.

"I'm not listening," she said childishly.

"You're trying to make me change my mind."

"Of course I am." She rested her cheek against one raised hand.

"I shall write the book whether you want me to or not. I'm not afraid of you, you see. You can instruct a solicitor to take out an injunction to stop me, but he won't succeed because I shall argue that you're innocent, and a court will uphold my right to publish in the interests of natural justice."

Olive slumped back on to her chair.

"I'll write to a Civil Liberties group. They'll support me."

"Not when they find out I'm trying to get you released, they won't.

They'll support me."

"The Court of Human Rights, then. I'll say what you're doing is an invasion of my privacy."

"Go ahead. You'll make me a fortune. Everyone will buy the book to find out what the fuss is all about. And if it's argued in a court, whichever one it is, I shall make d.a.m.n sure this time that the evidence is heard."

"What evidence?"

"The evidence that proves you didn't do it."

Olive slammed a meaty fist on to the table.

"I did do it."

"No, you didn't."

"I did!" roared the fat woman.

"You did not," said Roz, her eyes flashing with anger.

"When will you face up to the fact that your mother is dead, you silly woman." She banged the table in her turn.

"She's not there for you any more, Olive, and she never will be, however long you hide inhere."

Two fat tears rolled down Olive's cheeks.

"I don't like you."

Roz continued brutally.

"You came home, saw what your precious lover had done, and went into shock. And G.o.d knows, I don't blame you." She took the mortuary photographs of Gwen and Amber from her bag and slapped them on the table in front of Olive.

"You adored your mother, didn't you? You always adore the people who need you."

Olive's anger was enormous.

"That's c.r.a.p, b.l.o.o.d.y f.u.c.king c.r.a.p!"

Roz shook her head.

"I needed you. That's how I know."

Olive's lip trembled.

"You wanted to know how it felt to kill someone, that's all you needed me for."

"No." Roz reached across and took a large, soft hand in hers.

"I needed someone to love. You're very easy to love, Olive."

The woman tore the hand away and clamped it across her face.

"No one loves me," she whispered.

"No one's ever loved me."

"You're wrong," said Roz firmly.

"I love you. Sister Bridget loves you. And we are not going to abandon you the minute you get out. You must trust us." She closed her mind on the insidious voice that murmured warnings against a long-term commitment she could never keep and against well-meant lies that could so easily rebound on her.

"Tell me about Amber," she went on gently.

"Tell me why your mother needed you."

A sigh of surrender shuddered through the huge frame.

"She wanted her own way all the time, and if she didn't get it she made life h.e.l.l for everyone. She told lies about things people did to her, spread awful stories, even hurt people sometimes.

She poured boiling water down my mother's arm once to punish her, so we used to give in just to make life easy. She was as nice as pie as long as everyone did what she wanted." She licked the tears from her lips.

"She never took responsibility, you see, but it got worse after the baby was born. Mum said she stopped maturing."

"To compensate herself?"

"No, to excuse herself." She twined her fingers in the front of her dress.

"Children get away with behaving badly so Amber went on behaving like a child. She was never told off for getting pregnant. We were too afraid of how she would react." She wiped her nose with the back of her hand.

"Mum had made up her mind to take her to a psychiatrist. She thought Amber had schizophrenia." She sighed heavily.

"Then they were killed and it didn't matter any more."

Roz pa.s.sed her a Kleenex and waited while she blew her nose.

"Why did she never behave badly at school?"

"She did," said Olive flatly, *if people teased her or took her things without asking. I used to have to get quite angry to stop them doing it, but most of the time I made sure no one got on her bad side. She was a lovely person as long as she wasn't crossed. Really," she insisted, *a lovely person."

"The two faces of Eve."

"Mum certainly thought so." She took the cigarette packet out of Roz's open briefcase and stripped away the cellophane.

"I used to keep her with me when she wasn't in cla.s.s. She didn't mind that. The older girls treated her like a pet and that made her feel special. She had no friends of her own age." She pulled some cigarettes on to the table and selected one.

"How did she hold down a job? You weren't there to protect her then."

"She didn't. She never lasted anywhere longer than a month.

Most of the time she stayed at home with Mum. She made Mum's life a misery."

"What about Glitzy?"

Olive struck a match and lit the cigarette.

"The same. She'd only done three weeks and she was already talking about leaving. There was some trouble with the other girls. Amber got one of them sacked or something. I can't remember now.

Anyway, that's when Mum said enough was enough, and she'd have to see a psychiatrist."

Roz sat in thoughtful silence for some moments.

"I know who your lover was," she said abruptly.

"I know that you spent Sundays at the Belvedere in Farraday Street and that you signed in as Mr. and Mrs. Lewis. I've had his photograph identified by the owner of the Belvedere and by the receptionist at Wells Fargo I think he abandoned you in a hotel the night of your birthday when you told him you had aborted his baby, and that he went straight to Leven Road to have it out with Amber and your mother whom he regarded as jointly responsible for the murder of the son or daughter he had always wanted. I think your father was out of the house that night and that the whole thing got out of hand. I think you came home a long time afterwards, discovered the bodies, and went to pieces because you thought it was all your fault." She took one of Olive's hands in hers again and squeezed it tightly.

Olive closed her eyes and wept quietly, her soft skin caressing Roz's fingers.

"No," she said at last, releasing the hand.

"It didn't happen like that. I wish it had. At least I'd know then why I did what I did." Her eyes were curiously unfocused as if they were turned inwards upon herself.

"We didn't plan anything for my birthday," she said.

"We couldn't. It wasn't a Sunday and Sundays were the only days we could ever be together. That was when his sister-in-law came over to give him some time away from his wife. They both thought he spent the day at the British Legion." She smiled but there was no humour in it.

"Poor Edward. He was so afraid they'd find out and turn him off without a penny. It was her house and her money and it made him miserable. Puddleglum was such a good name for him, especially when he wore his silly wig. He looked just like a marsh wiggle out of Narnia, tall and skinny and hairy." She sighed.

"It was supposed to be a disguise, you know, in case anyone saw him. To me, it just looked funny. I liked him much better bald." She sighed again.

"The Silver Chair was Amber's and my favourite book when we were children."

Roz had guessed.

"And you signed in as Mr. and Mrs. Lewis because it was C. S. Lewis who wrote it. Were you afraid of Mrs. Clarke finding out, or your parents?"

"We were afraid of everyone but mostly of Amber. Jealousy was a disease with her."

"Did she know about your abortion?"

Olive shook her head.

"Only my mother knew. I never told Edward and I certainly didn't tell Amber. She was the only one who was allowed to have s.e.x in our house.

She did, too. All the time. Mum had to force her to take the pill every night so she didn't get pregnant again." She pulled a long face.

"Mum was furious when I fell. We both knew Amber would go mad."

"Is that why you had the abortion?"

"Probably. It seemed the only sensible solution at the time.

Iregret.i.tnow."

"You'll have other chances."

"I doubt it."

"So what did happen that night?" asked Roz after a moment or two.
