‘How can I help you, Sergeant?’ Theo asked. He looked almost as shocked by the intrusion as she was herself.

‘I’d like a word with Miss Lydia Ivanova, if I may.’ The policeman in his dark uniform overpowered the classroom; his broad shoulders and big feet seemed to fill the space between the floor and the ceiling. His manner was polite but curt.

Mr Theo walked over to Lydia and rested a hand on her shoulder. She was surprised by his support.

‘What is this about?’ he asked the sergeant.

‘I’m sorry, sir, I can’t discuss that. I just need to take her down to the police station for a few questions.’

Lydia was so panicked by his words that she even thought of making a run for it, but she knew she didn’t stand a chance. Anyway her legs were trembling too much. She’d just have to lie, and lie well. She stood up and gave the sergeant a confident smile that made the muscles of her cheeks hurt.

‘Certainly, sir. I’m happy to help.’

Mr Theo patted her back and Polly gave her a grin. Somehow Lydia made her legs move, one foot in front of the other, heel-toe, heel-toe, heel-toe, and wondered if anyone else could hear the banging in her chest.

‘Yes.’

‘You were searched.’

‘Yes.’

‘Nothing was found.’

‘No.’

‘I’d like to apologise for the indignity.’

Lydia remained silent. She watched warily. He was laying a trap for her, she was certain, but she couldn’t yet see how or where.

It was Commissioner Lacock himself, so she knew she was in real trouble. Just being in the police station at all was bad enough, but to be escorted into the commissioner’s office and told to sit down in front of his big glossy desk made her hear the clang of the prison cell door in her head. Shut in. Four bare walls. Cockroaches and fleas and lice. No air. No life. She was frightened she would blurt it out, confess everything, just to get away from this man.

‘You gave me a statement that night.’

She wished he’d sit down. He was standing behind his desk with a sheet of paper in his hand - what was on it? - and was studying her with grey eyes so sharp she could feel them piercing through each layer of her lies. The monocle just made it worse. His uniform was very dark, almost black, full of gold braid and bright silver bits that she felt were designed to intimidate. Oh yes, she was intimidated all right but had no intention of letting him know it. She concentrated on the tufts of hair poking out of his ears and the ugly liver spots on his hands. The weak bits.

‘Commissioner Lacock, has my mother been informed I’m here?’ She made it haughty. Like Countess Serova and her son Alexei.

He frowned and rubbed an impatient hand across his thinning hair. ‘Is that necessary at the moment?’

‘Yes. I want her here.’

‘Then we shall fetch her.’ He gave a nod to a young policeman positioned by the door, who promptly disappeared. One down, one more to go.

‘And do I need a lawyer?’

He placed the sheet of paper on top of a pile on his desk. She wanted to read it upside down but didn’t dare take her eyes from his. He was staring at her with what looked like an amused expression. Cat and mouse. Play before you pounce. Her hands were sweating.

‘I hardly think so, my dear. We’ve only asked you down here to pick a man out of a lineup.’

‘What?’

‘Yes, the man you described in your statement. The prowler you saw through the library window of the Ulysses Club. Remember him?’

He was waiting for a reply. Relief had robbed her of breath. She nodded.

‘Good, then let’s go and take a look at them, shall we?’

He walked over to the door and to Lydia’s amazement her own legs followed as if it were easy.

‘Take your time, Miss Ivanova, and remember what I told you,’ Lacock said and led her to one end of the row. ‘Eyes front,’ he ordered sharply and it took her a moment to realise it was addressed to the six men.

What had he told her? She tried to recall but the sight of the row of silent men had jammed her mind. She couldn’t take her eyes off them. All the same, yet all so different. Some were taller or broader or older. Some were mean and arrogant, others were bowed and broken. But all had black bushy beards and wild hair, and were dressed in rough tunics and long boots. Two had a dark leather patch over one eye and one had a gold tooth that glinted like an accusing eye at her.

‘Don’t be nervous,’ Lacock encouraged. ‘Just walk slowly down the line, looking at each face carefully.’

Yes, that’s right, she was remembering his instructions now, walk along the row, say nothing, then walk the row a second time. Yes. She could do it. And then she’d say it was none of these men. Easy. She took a deep breath.

The first face was cruel. Hard cold eyes, a twisted lip. The second and third were sad with gaunt faces and a hopeless air, as if they expected nothing except death. The fourth was proud. He wore an eye patch and held himself well, sticking out his barrel chest, his oily curls unable to hide the long scar on his forehead. This one looked her straight in the eye and she knew him at once, the big bear of a man she’d seen down in her street the day before the concert. The one with the howling wolf on his boots. He was the man she’d described to the police in the hope of distracting their attention from herself. She kept her own face blank and moved on to the last two, but she barely saw them. An impression of bulk and muscle and a crooked nose. Number Six wore an eye patch, she noticed that. Stiffly she walked back to the beginning and put herself through it once more.

‘Take your time,’ Lacock murmured again in her ear.

She was going too fast, slowed her pace, made herself stare into each grim dark face. This time Number Four, the one with the wolf boots, raised an eyebrow at her, which made the commissioner rest his baton heavily on the man’s shoulder.

‘No liberties,’ he said in a voice accustomed to instant obedience, ‘or you’ll spend the night in jug.’

Just when Lydia thought it was all over and she could escape this dismal green room, it got worse. The last man spoke. He was smaller than the rest but still big and wore the eye patch. ‘No say it’s me, miss. Please not. I got wife and . . .’

A baton in the hand of the sergeant slammed into the side of his head. Blood spurted out of his nose and over Lydia’s arm. The sleeve of her white school blouse turned red. She was bundled out of the room before she could open her mouth, but the moment she was back in Commissioner Lacock’s office she started to complain.

‘That was brutal. Why did . . . ?’

‘Believe me, it was necessary,’ Lacock said smoothly. ‘Please leave the policing to us. If you give those Russkies - excuse the expression - an inch, they’ll take a mile. He was told to say nothing and he disobeyed.’

‘Were they all Russians?’

‘Yes, Russians and Hungarians.’

‘Would you have treated an Englishman like that?’

Lacock frowned heavily and looked as if he were about to say something sharp to her, but instead asked, ‘Did you recognise any of them as the face of the prowler you saw at the Ulysses Club?’

She shook her head. ‘No.’

‘Are you sure?’

‘Yes. Absolutely certain.’

His shrewd eyes studied her carefully, and then he leaned back in his chair, removed his monocle, and spoke in a concerned voice. ‘Don’t be nervous of telling the truth, Lydia. We won’t let any of those men come anywhere near you, so you needn’t be afraid. Just speak out. It’s the Russki with the scar on his forehead, isn’t it? I can tell you’ve seen that one before.’

Abruptly the room was spinning around her and the commissioner’s face was receding into a tunnel. There was a booming in her ears.

‘Burford,’ Lacock ordered, ‘bring the girl a glass of water. She’s as white as a sheet.’

A hand touched her shoulder, steadied her swaying body; a voice was saying something in her ear but she couldn’t make it out. A cup was pressed to her lips. She took a sip, tasting hot sweet tea, and gradually something began to penetrate the mists that fogged her brain. It was a smell. A perfume. Her mother’s eau de toilette. She opened her eyes. She hadn’t even realised they were closed, but the first thing they saw was her mother’s face, so close she could have kissed it.

‘Darling,’ Valentina said and smiled. ‘What a silly you are.’

‘Mama.’ She wanted to cry with relief.

Her mother held her close and Lydia breathed in her perfume till it cleared her head, so that when Valentina released her she was able to sit up straight and accept the cup of tea with a steady hand. She looked directly at Commissioner Lacock.

‘Commissioner, there was no face at the window the night the necklace was stolen.’

‘What are you saying, young lady?’

‘I made it up.’

‘Now look here, there’s no need to back out just because you’ve seen a roomful of rough rogues who have put the fear of the devil into you. Tell the truth and shame the devil, that’s . . .’

‘Mama, tell him.’

Valentina looked at her and made a little grimace with her mouth that Lydia knew meant she was annoyed.

‘As you wish, dochenka.’ She lifted her head, sending her hair rippling in a dark wave around her shoulders, then turned serious eyes on the chief of police. ‘My daughter is a lying little minx who should be whipped for wasting police time. She saw no face at the window. She makes up such stories to get attention. I apologise for her misbehaviour and promise to punish her severely when I get her home. I had no idea her stupid tale would be taken so seriously or I would have come and told you before now not to believe a word of it.’

She lowered her eyelashes for a moment in a display of maternal distress, then looked up slowly and fixed her eyes on Lacock’s. ‘You know,’ she said softly, ‘how silly adolescent girls can be. Please excuse her this time, she meant no harm.’ She turned her dark gaze on her daughter. ‘Did you, Lydia?’

‘No, Mama,’ Lydia murmured and had to bite back a smile.

‘Yes, Mama.’

‘You are a disgrace to me.’

‘I know, Mama. I’m sorry.’

‘Where in God’s name did I go wrong? You are a wild thing and deserve to be locked up in a cage. You know that’s true, don’t you?’

‘Yes, Mama.’

‘So.’ She stood in the middle of the pavement with her hands on her hips and stared at her daughter. ‘What am I to do with you?’ She was wearing an old but stylish linen suit the colour of ice cream, and it made her pale skin look like silk. ‘I’m so pleased the commissioner gave you such a telling off. Good for him. He had every reason to. Don’t you agree?’

‘Yes, Mama.’

Suddenly Valentina burst out laughing and gave Lydia a quick kiss on her forehead. ‘You are wicked, dochenka,’ she said and rapped her daughter’s knuckles with her clutch bag. ‘Take yourself off back to school now and don’t you ever give them reason to drag me to that police station again. You hear me?’

‘Yes, Mama.’

‘Be good, my sweet.’ Valentina laughed and stuck out a hand for a rickshaw. ‘The offices of the Daily Herald,’ she called to the coolie as she jumped in, leaving Lydia to walk up the hill to school.

She sat in the shade on the paving stones in the little backyard and fed Sun Yat-sen strips of a cabbage leaf she had scrounged from Mrs Zarya. She scratched the bony top of his head where he liked to be rubbed and ran her hand over the silky fur of his long ears. She envied him the ability to find total happiness in a cabbage leaf. Though she did understand it. Valentina had brought home a box of Lindt chocolates last night, a big white and gold one, and they had eaten pralines and truffle cones for breakfast. It had felt like heaven. Alfred was certainly generous.

She tucked her legs up tight against her chest and sank her chin onto her knees. Sun Yat-sen stood up on his hind legs, rested a soft front paw on her shin, and twitched his nose in her hair while she traced a finger down the long line of his spine and wondered how far a person would go to have someone to love. Alfred was in love with her mother. Oh, any fool could see that. But how did Valentina feel about Alfred? It was hard to say, because she was always so bloody private about what went on in her head, but surely she couldn’t love him. Could she?

Lydia thought about that till the sun had disappeared completely behind the roof ridge, about exactly what it meant to be loved and protected. Then she wrapped her arms round the rabbit and held him close, her cheek tight against his little white face. He never seemed to mind how much she squeezed him; it was one of the things she adored about him, his squashiness. She kissed his pink nose and decided to let him roam loose in the yard and hope Mrs Zarya wouldn’t notice, before she ran up to the attic and snatched a knotted handkerchief from under her mattress.

The handkerchief lay heavy in her pocket as she made her way across to the old Chinese town, and her footsteps quickened at the thought that she might bump into Chang somewhere in its narrow cobbled streets. But all she encountered were cold hostile stares and the hiss of words that made her want Chang at her side. It annoyed her that she had no idea where he lived, but she’d never yet felt able to ask him outright, to tear aside that strange cloak of secrecy he hid under. But next time she would. Next time? Her heart gave a little clatter under her ribs.

Lydia stood and stared in horror at Mr Liu’s shop front. At where it had been. It was now a naked gaping hole. Everything was smashed into thousands of pieces; his glass window, his red latticework, his printed signs and scrolls, even the door and its frame lay twisted on the ground. The shops of the candlemaker and the charm seller on each side of it were untouched, open for business as usual, so whatever or whoever had done this had aimed it just at him. At Mr Liu. She stepped inside what was left of the pawnbroker’s, but it was no longer dark and secretive. Sunlight strode in, exposed the packed shelves to any passing gaze, and Lydia felt a sharp tug of sympathy for the place. She knew the value of secrets. In the centre of the room Mr Liu sat still as stone on one of his bamboo stools, while across his knees lay the long blade of the Boxer sword that used to hang on the wall. There was blood on it.

‘Mr Liu,’ she said softly, ‘what happened?’

He raised his eyes to her face, and they were older, much older. ‘Greetings to you, Missy.’ His voice was like a faint scratching on a door. ‘I apologise that I am not open for business today.’

‘Tell me what happened here?’

‘The devils came. They wanted more than I could give.’

Around his feet the jewellery display cases were crushed and empty. Lydia felt a lurch of alarm. The shelves didn’t look as if they had been touched, but the really valuable stuff was gone.

‘Who are these devils, Mr Liu?’

He shrugged his thin shoulders and shut his eyes. The world blocked out. She wondered what inner spirits he was calling on. But what she couldn’t understand was why nothing was being done to clear up the mess, so she went over to where the inlaid screen used to stand, now trampled into the floor, and set his kettle on the little stove at the back. She made them both a cup of jasmine tea on a tray and carried it over to him and his sword. His eyes were still closed.

‘Mr Liu, something to cool your blood.’

A faint flicker of a smile moved his lips and he opened his eyes.

‘Thank you, Missy. You are generous, and respectful to an old man.’

Only then did she realise the oiled queue that used to hang down his back had been chopped off and was lying on the floor, and his long tufty beard had been hacked back to grey stubble. The indignity of such an act overwhelmed her for a moment. Worse than the attack on the shop. Far, far worse.

She pulled up the other stool and sat down on it. ‘Why doesn’t anybody come to help?’ People were passing in full view of them, but their faces looked the other way.

‘They are afraid,’ he said and sipped the scalding liquid with indifference. ‘I cannot blame them.’

Lydia stared at the sword, at the blood turning brown. The attack must have happened only shortly before she arrived because part of it still glistened on the blade.

‘Who are these devils?’

A long silence settled in the shop alongside the dust and the shattered glass while Mr Liu started to breathe deeply in and out, long and slow.

‘You don’t want to know such things,’ he said at last.

‘I do.’

‘Then you are a fool, Missy.’

‘Was it the Communists? They need money for guns, I hear.’

He turned his black eyes on her, surprised. ‘No, it was not the Communists. Where does a foreigner such as you hear of those people?’

‘Oh, around. Word spreads.’

His eyes were sharp. ‘Take care, Missy. China is not a place like others. Here different rules apply.’

‘So who are the devils who make up the rules that say they can destroy your shop and take your money? Where are the police? Why don’t they . . . ?’

‘No police. They will not come.’

‘Why not?’

‘Because they are paid not to come.’

Lydia felt cold, despite the tea. Mr Liu was right; this was not her world. Chinese police were not like Commissioner Lacock. The chief of police in the International Settlement, whom she had loathed so passionately only a couple of hours ago, suddenly appeared to be a reasonable and honourable figure. Respected and reassuring. She wanted his monocle and his authoritative voice to storm up here and sort out this mess. But this was not in his jurisdiction. This was Chinese Junchow. She sat in silence. Nothing was said for so long that it came as a slight shock when Mr Liu lifted up the sword in one hand, pointing it straight out in front of him, and said, ‘I cut one.’

‘Badly?’

‘Bad enough.’

‘Where?’

‘I sliced the tattoo off his neck.’ He said it with quiet pride.

‘Tattoo? What kind of tattoo?’

‘What is it to you?’

‘Was it a snake? A black snake?’

‘Maybe.’

But she knew she was right. ‘I’ve seen one.’

‘Then look away or the black snake will bite out your heart.’

‘It’s a gang, isn’t it? One of the triads. I’ve heard about these brotherhoods that extort money from . . .’

He held a hooked finger to his lips. ‘Don’t even speak of them. Not if you want to keep your pretty eyes.’

She slowly placed her tiny cup on the enamelled tray on the floor. She didn’t want him to see her face. He had frightened her.

‘What will you do?’ she asked.

He brought the sword crashing down onto the tray, slicing it neatly in half and making Lydia leap to her feet.

‘I will pay them,’ he said in a whisper. ‘I will find the dollars somewhere and pay them. It is the only way to put food on my family’s table. This was just a warning.’

‘Can I help you sweep up the glass and . . . ?’

‘No.’ It was harsh the way he said it, as if she’d offered to chop off his feet. ‘No. But thank you, Missy.’

She nodded. But did not leave.

‘What is it, Missy?’

‘I came to do business.’

He spat viciously on the floor. ‘I have no business today.’

‘I came to buy, not to sell.’

It was as if a key turned. His dull eyes brightened and he found his shopkeeper’s smile. ‘How can I help you? I’m sorry so much is damaged but . . . ,’ he glanced to the rail at the back of the shop, ‘the furs are still in excellent condition. You always liked the furs.’

‘No furs. Not today. What I want is to redeem the silver watch I brought last time.’ She slid her hand into her pocket where the handkerchief lay. ‘I have money.’

‘So sorry, it is already sold.’

Her small cry of dismay surprised him. He studied her face carefully.

‘Missy, today you have been good to an old man when no one of his own kind would even look at him. So today you have earned a kindness in return.’ He walked over to the black stove and lifted down a brown glazed pot from the shelf that held the lacquered tea caddies. He opened it and took out a small felt package.

‘Here,’ he said. ‘How much did I pay you for the watch?’

Not for one moment did she think he had forgotten.

‘Four hundred Chinese dollars.’

He held out his frail bird-claw hand.

From her pocket she lifted out the handkerchief containing the money and placed it in his palm. His fingers closed quickly around it. She took the felt package and, without even looking at it, put it in her pocket.

He was pleased. ‘You bring the breath of fire spirits with you, Missy.’ He watched her for a moment, and she tucked a copper strand of hair behind her ear self-consciously. ‘You take risks coming here, but the fire spirits seem to guard you. You are one of them. But a snake has no fear of fire, he loves its warmth, so tread carefully.’

‘I will.’ As she picked her way out through the debris, she looked back over her shoulder. ‘Fire can devour snakes,’ she said. ‘You watch.’

‘Stay away from them, Missy. And from the Communists.’

The mention surprised her. On impulse she asked, ‘Are you a Communist, Mr Liu?’

His face barely changed, but she felt the door slam down between them.

‘If I were foolish enough to be a supporter of Communism and of Mao Tse-tung,’ he said in a louder voice, as if talking to someone out in the street, ‘I would deserve to have my head rammed on a stake on the town wall for all the world to throw filth at.’

‘Of course,’ she said.

He bowed to her, but not before she saw the smile.
