Chang swept through the darkness. Winding and twisting. Ambushing. One man lost the use of a leg and another the sight in one eye. But a nighttime honey wagon, the cart piled high with human manure and the stench enough to choke a man, blocked his path and he was forced to swerve left down a slope that led nowhere.

A death trap.

Sheer walls on three sides of a rough courtyard. One way in. One way out. Six men spread behind him, breathing hard and spitting venom. Three of them carried knives, two wielded swords, but one held a gun and it was pointed straight at Chang’s chest. He said something guttural and a sword carrier stepped forward. He came at Chang and the long blade sang through the air. Chang stilled his breathing, drew on the energy racing through his blood, and in one fluid movement swept a leg under his attacker. A sting of pain skittered down his side, but he took three rapid steps and leaped into the air at the back wall, struggled for a fingerhold, slipped, caught again, and then swung his heels over his head in a full arc. On the roof but not safe. A bullet tore past his ear.

A howl of anger down in the courtyard and the man with the gun seized the swordsman’s weapon and sliced it down in a blow that disembowelled the sword’s owner. The wounded man fell forward to his knees, clutching at his writhing innards as they spilled from his body, a high wailing scream rising from his mouth. A second blow from the sword silenced the scream and sent his head rolling into the gutter. The gun pointed once more at the roof. But Chang was gone.

Lydia had time to think. The stretch of twenty-two yards at the centre of the pitch was wearing thin, but around it the turf spread out like a shimmering lake of green. The grass was trimmed with precision and treated with a respect that baffled her because the men seemed to pay more attention to its welfare than they did to their children’s. But she loved to watch cricket. She liked to imagine this same scene taking place on the other side of the world in England. At this very moment in every town and village the weekend was being besieged by men in white flannels strutting around with pads and bats, knocking hell out of a small hard ball. It was so wonderfully pointless. Especially in this heat. Only people with nothing to do all day could think up a game so bizarre.

Men in white.

To one nation it means a game. To another it means death. Worlds apart. Oceans adrift. But what happens to someone caught in the middle? Do they drown?

‘More tea, dear? You look miles away.’

‘Thank you, Mrs Mason.’ Lydia accepted the tea, drew her thoughts away from Chang An Lo, and helped herself to another cucumber sandwich, which she added to the plate balanced on the arm of her deckchair.

Polly’s mother was wearing heavy sunglasses and a wide-brimmed hat trimmed with roses from her garden, but neither quite hid the bruise around her left eye or the swelling on her cheekbone. ‘I tripped over Achilles, Christopher’s lazy old cat, and banged into a door, silly me,’ Lydia had heard her laugh to the other wives, but it was obvious from their expressions that no one believed the lie. Lydia looked at her with new respect. To come here today for the match and face up to this humiliation with such a firm smile and a steady hand as she dispensed tea, that took courage.

‘Mrs Mason,’ she said in a loud voice, ‘that is such a pretty dress, it really suits you.’ It was frilly and floral, the kind of dress only an Englishwoman would wear.

‘Why, thank you, Lydia,’ Anthea Mason said, and for one ghastly moment Lydia thought she was going to cry, but instead she popped a smile on her face and an extra sandwich on Lydia’s plate.

Out on the field Christopher Mason hit another four, but Lydia refused to join in the ripple of applause. Beside her Polly beamed with delight and fondled her puppy’s head to cheer him up. He was sulking at being kept on a lead when the ball was just asking to be fetched.

‘Isn’t Daddy clever, Toby? He’ll be in such a good mood today.’

Lydia wouldn’t look at her.

‘You’ll get yourself killed, Lyd.’

‘Don’t talk such poppycock. It was only a funeral.’

‘But why? No one goes to Chinese functions. The natives here keep to themselves and we do the same. That way everyone stays happy. You’ve got to accept that they don’t like us, Lyd, and they’re different from us. Mixing together. It can’t be done.’

‘How do you know?’

‘Because it can’t. Everyone knows that.’

‘You’re wrong. Chang and I are…,’ Lydia sought for a word that wouldn’t shock Polly, ‘… friends. We talk about… well, about things, and I see no reason why we can’t mix. Look at all the children who have amahs as nannies to look after them when they’re little and they really love them. So why does it have to change just because the children grow up?’

‘Because they have different rules from us.’

‘So you’re saying it only works when they adopt our rules and live as we live.’

‘Yes.’

‘But they’re just people, Polly. Like us. You should have seen and heard their grief at the funeral. They were hurting just like we do. Cut them and they bleed. So what do rules matter?’

‘Oh, Lyd, this Chang An Lo is getting you all muddled up. You must forget about him. Though I must admit Mr Theo seems to make it work with his beautiful Chinese woman.’

‘But he hasn’t married her, has he?’

‘Exactly.’

‘And when Anna Calpin was young she used to love her amah, but now she makes her sit on the toilet seat for ten minutes when it’s cold in winter to warm it up before Anna uses it.’

‘I know. But you’ve never had Chinese servants, Lyd. You don’t understand.’

‘No, Polly. I don’t.’

The street seemed normal. A Chinese vendor stood on the corner trying to sell sunflower seeds and hot water, a boy was playing marbles in the gutter, and an old Russian babushka was sitting in a rocking chair in her doorway, plucking a guinea fowl. At her feet two filthy street urchins were snatching at feathers as they fell and stuffing them into a pillowcase. The big wheels of a rickshaw rattled down the road kicking up grit.

Lydia tried to work out what had made her halt. It was the street where she lived. She’d walked it a million times. It was hot, she was dusty, and her dress was sticking to her skin. She needed a cold drink. Only twenty yards to her own front door. So what was it? What made her hesitate?

Be watchful, Lydia Ivanova. Don’t sleep while you walk. They let you go once but not a second time. Chang’s words to her. Well, she was being watchful all right, keeping alert, yet she could see nothing to be nervous about. Oh hell, maybe Polly was right. Maybe he was getting her head all muddled over nothing. She hurried down the street, impatient with herself, and it was as she was unlocking the front door that she sensed the movement behind her. Not that she saw or heard anything. More a sudden shifting of the air at her back. She didn’t turn. Just threw herself over the threshold and slammed the door behind her. She leaned heavily against it, not breathing. Listening.

Nothing. A car’s klaxon, a child’s laugh, the savage shriek of a gull overhead.

She took a deep breath. Had she imagined it?

She waited while the minutes ticked by, and still her pulse thudded in her ears.

‘Lydia, moi vorobushek, come here, come.’ It was Mrs Zarya beckoning at the end of the hall. She was wearing a bright pink kimono, and her hair was wrapped up in wire curlers. ‘I have a piece of yam for your Mr Sun Yat-sen. Here, take it.’

Lydia moved, but her feet felt heavy. ‘That’s kind, Mrs Zarya. Sun Yat-sen will like that.’ She remembered the clutch of grass that she’d sneaked from the cricket club. It was scrunched tight in her hand. ‘Going somewhere special tonight?’
