'Lydia Ivanova, may your words scorch holes in your tongue.'

Lydia said nothing. Her cheeks were burning.

'They'll arrest him, you know,' Valentina said fiercely.

No, how could they?

'Your description marked him out clearly as a Russian. They'll search around here in the Russian Quarter until they find a man that fits. Then what?' Her mother's voice wouldn't let up.

Please don't let them find him.

'It was a foolish lie to tell, Lydia. It puts others at risk.'

Still Lydia didn't open her mouth. She was afraid what words might creep out.

'Pah! Go into one of your sulks, if you must.' Valentina's voice was heavy with annoyance. 'Dear G.o.d, what a terrible night this has been. No concert, so no fee, searched by an insolent nurse, and now a daughter who not only ruins her beautiful dress by running around in the rain but also insults me with her lies and silence.'

No response.

'Go on, go to sleep then, and I hope you dream of your bearded Russian phantom. Maybe he'll come after you with a pitchfork to thank you for your lies.'

Lydia lay in her bed staring out into the darkness, too frightened to shut her eyes.

'h.e.l.lo, dear, you're up bright and early this morning. Come to tell Polly all about the thrills of last night, have you? Goodness me, what a kerfuffle it was.'

Anthea Mason beamed with pleasure at Lydia, as if she could think of no better way to start a Sunday morning than having her daughter's friend arrive on her doorstep before breakfast.

'Come and join us on the terrace.'

This wasn't exactly what Lydia had planned, because she needed to speak to Polly in private, but it was better than nothing, so she smiled a thank-you and followed Mrs Mason through the house. It was large and very modern, with pale beechwood floors, and always seemed filled with light as if it had somehow swallowed the sun, which danced off the plain cream-painted walls and caressed the shiny bra.s.s horn of the gramophone that Lydia coveted with a pa.s.sion. No peeling wallpaper or dingy corners for c.o.c.kroaches here. And Polly's house always smelled so enticing. Of beeswax polish and flowers and something homemade baking in the oven. Today it was coffee and fresh rolls.

As she emerged onto the terrace with its view over a sun-dappled lawn and yellow tea roses, the image was idyllic. A table was covered in starched white linen and spread with teacups that had fragile little handles and gold rims, and a silver coffeepot was surrounded by perfectly matching silver bowls of sugar, b.u.t.ter, marmalade, and honey. Mr Mason was relaxing in his shirt-sleeves and riding boots at one end of the table, with a newspaper in one hand, a slice of toast in the other, and Achilles on his lap. Achilles was a fat cat with long grey fur and a voice like a foghorn.

'Hi, Lyd.' Polly smiled from the other side of the table and tried to hide her surprise.

'h.e.l.lo.'

'Good morning, Lydia,' said Mr Mason. 'A bit too d.a.m.ned early for visitors, wouldn't you say?' His tone was one she'd heard him use to the boot boy. She couldn't bear to look at him. Instead she stared at the delicate finger bowl beside him, and became curious about the slice of lemon floating in the water.

'Yes, sir.'

'So why are you here?'

'Oh, Christopher,' said Anthea Mason, 'we're always happy to see Lydia any time, aren't we, Polly? Sit and have a bite to eat, dear.'

But Lydia would rather swallow her tongue than sit down at the same table with the man who last night had been molesting her mother. Both she and Valentina had carefully avoided mentioning the subject of what they both knew Lydia had seen, but the pictures were still vivid inside her head.

'No, thank you,' she said politely. 'I just want a word with Polly, if I may.'

Mason leaned back in his chair and tossed the paper to the ground. 'Now then, young lady,' he said, 'whatever you want to say to our daughter can be said in front of us. We have no secrets round here.'

The barefaced lie. It made Lydia blink, and she opened her mouth to utter a sharp retort, but Polly forestalled her. She jumped to her feet, grabbing the napkin from her lap. Lydia knew for a fact it had come from London, from a shop called Givan's on New Bond Street, twenty-nine shillings and ninepence for a dozen, Polly had told her proudly, all fine Irish damask. Whatever that was.

'Daddy, we'll just find Toby and walk him down to the park.'

'That'll be fun for him. Take his ball and don't forget to wear your hat,' Anthea Mason said with a look at her husband.

He turned his face away from her and gave a smile to the cat draped across his lap, its yellow eyes watching him closely. 'Don't be long.'

'No, just a quick run,' Polly said.

'Church at eleven sharp. I don't want you making us late.'

'We won't, I promise.'

As she pa.s.sed him, he reached up and ruffled her blond hair, but to Lydia the gesture looked awkward, as if it were something he'd once seen a father do and decided to copy it. Polly's cheeks turned pink, but then she was always nervous around her father and never talked about him, not even in private. Lydia, knowing nothing about fathers, a.s.sumed this was normal.

'Polly, I need a favour.' Lydia clutched her friend's arm.

'What is it?'

'A big favour.'

Polly's eyes grew bluer and rounder. 'I just knew it had to be something really important for you to barge in on Father so early. What is it? Quick, tell me.' She twirled Toby's lead in her hand.

They were sitting on a bench in the sunshine, throwing b.a.l.l.s for Polly's Tibetan spaniel. They had avoided Victoria Park with its No Dogs. No Chinese notices and opted for Alexandra Gardens, where Toby was allowed to race around, as long as he kept out of the canna flowerbeds and the koi fish pond, where frogs lurked under lily pads and taunted his insatiable nose.

'It's . . . well . . . you see . . . oh Polly, I need to get back into the club.'

'What? The Ulysses Club?'

'Yes.'

'But why?'

'I just do.'

'That's no answer.' Polly twisted her pretty face into a scowl, but there was no conviction in it. She was never much good at being cross with Lydia, but tried to keep that fact a secret. 'I thought that last night would have put you off that club for life. It would me. To be searched by a ghastly old nurse.' She gave a dainty little shudder that rippled through her soft blond hair. 'How perfectly disgusting.' She leaned closer, eyes fixed on Lydia's. 'Was the search very, you know, very sort of . . . intimate? ' She held her breath.

'Oh G.o.d, yes.'

Polly's mouth popped open and she gave a gasp. 'Oh Lyd, that's horrible. Poor you.' She gave her friend a quick hug.

'So?'

'So what?' Polly asked.

'So will you speak to your father for me?'

'Oh Lyd, I can't.'

'You can, you know you can. Please, Polly.'

'But why do you want to go back to the club? They searched everyone and every room but didn't find the stolen necklace. So what can you do?' She glanced around quickly and lowered her voice to a bare whisper. 'Did you see something? Do you know who took it?'

'No, no, of course not, or I'd have told the police.'

'Then why?'

'Because . . . oh, all right, I'll tell you, but you must promise to keep it secret.'

Polly nodded eagerly, licked a finger and drew a cross on her throat. 'Hope to die.'

'Remember the young man who rescued me in the alley on Friday? With his flying kung fu kung fu kicks . . .' kicks . . .'

'Yes?'

'Well, he turned up at the club last night.'

'No.'

'Yes.'

'Did he steal the necklace?'

'Don't be silly,' Lydia said quickly, 'of course he didn't. He had come especially to speak to me about something. He said it was important. But we were interrupted by all the police running around after they discovered the necklace had gone, so he asked me to come back today . . . I really owe it to him, Polly, and I don't know where else to find him.'

To Lydia's horror, she suddenly realised her fingers were tugging at a strand of hair just in front of her right ear. Oh d.a.m.n. Her mother was right. She dropped it quickly, gave Polly a sideways glance to see if she'd noticed, and bent to pick up Toby's ball.

'But there's something I don't understand, Lyd.'

Lydia threw the ball for the dog.

'You say your mother hardly ever scolds you, Lyd, just lets you do what you like. That's why I'm green with envy, you know that. I wish I had the freedom she allows you.' She turned and looked quizzically at her friend. 'So why all the secrecy? Can't your mother . . . or even her French friend with the Morgan . . . can't they get you in?'

Lydia hated lying to Polly, the one person in the whole world she was honest with, but she had to get back inside the club today if she was to retrieve the rubies from their hiding place in the Reading Room. And now Polly was being stubborn.

Lydia leaped to her feet and tossed her head impatiently. 'Neither my mother nor Antoine are members, as you well know. But if you're too scared to ask your father to invite me in there, I'll ask him myself.'

'But he'll want to know why.'

'That's okay, I'll tell him I lost a brooch or something last night.'

'He'll only get annoyed and say if you can't look after something properly, you don't deserve it in the first place.'

'Oh, Polly, you are such a baby,' Lydia snapped and stalked off toward the park gates.

But Polly came running after her with Toby bouncing around her ankles. 'Please, Lyd, don't be angry.'

'I'm not.'

But she was. Angry with herself. She turned and looked at Polly, at her lovely pale cornflower dress, at her smart patent leather shoes and at her wide blue eyes creased with worry, and hated herself. She had no right to drag this shiny new silver dollar of a person through the dirt. She was so used to it herself, she forgot that others found its smell distressing. She drew Polly's arm through her own and gave her a shaky smile.

'Sorry, Polly, I know I'm too hotheaded sometimes.'

'It's the red hair.'

They both laughed and felt the friendship slip back in place.

'Okay, I'll ask Father.'

'Thanks.'

'But it won't work.'

'Please try.'

'On condition you tell me more about your mystery Chinese rescuer after you see him again.' She paused, attached her puppy to the lead once more, ruffled his ears, and, while her face was averted, asked, 'You don't think it might be a bit dangerous? I mean, you know nothing about him, do you?'

'Except that he saved me from slavery . . . or worse.' Lydia laughed. 'Don't fret, you silly. I promise to tell you everything that happens.'

'Describe him again to me. What's he like?'

'My flying hawk?'

'Yes.'

Lydia was nervous. She was longing to talk about her Chinese protector, to give voice to the images that crowded her thoughts, to talk of the high arc of his eyebrow that rose like a bird's wing and the way he angled his head when he was listening to you, his eyes stealing the thoughts behind your words. She could feel her eagerness to see him again like a hot stone in her chest and she didn't know why. She told herself it was just that she needed to thank him again and to see if he was hurt. That was all. Just politeness.

But she was no better at telling lies to herself than she was at deceiving Polly. And it frightened her, this sudden sense of losing herself in a labyrinth of unknown paths. Frightened and excited her. Something fluttered in the back of her mind and she pushed it away. The barriers between his world and hers were so high, and yet somehow they vanished when she was with him. Polly wouldn't understand.

She didn't even understand it herself, and didn't dare tell Polly the truth of last night.

'Is he handsome?' Polly prompted with a smile.

'I didn't notice much about him,' Lydia lied. 'His hair is cut short and his eyes are . . . I don't know, they sort of . . . ,' They reach out and see under my skin. Can I say that? They reach out and see under my skin. Can I say that? ' . . . sort of watch you,' she finished lamely. ' . . . sort of watch you,' she finished lamely.

'And he's strong?'

'He moved fast in the fight, like . . . a hawk.'

'Has he got a hawk nose as well?'

'No, of course not. His nose is perfectly straight and when he's not speaking his face is so still it looks like fine porcelain. And his hands are long with fingers that . . .'
