Her thoughts shut down. It was too much. She pushed the images out of her mind, but she couldn’t push away so easily the images of Chang’s intent eyes and the whisper of his touch on her arm. It echoed through her, spreading over her skin from limb to limb.

She tried to work out what it was about him that was different tonight. He was thinner, yes, but it wasn’t that. He’d always been lean. No, it was something about his face. In his eyes, in the set of his mouth. She had seen that same kind of expression once before, on Polly’s face when her beloved cat Benji was run over. A look of constant pain. Not pain like when she’d sewn up Chang’s foot. Something deeper. She longed to know what had happened to him to cause such a change since that day at Lizard Creek, but at the same time she swore to herself she would never ever speak to him again. Tonight he’d made her feel… what? What? What?

Bad. He’d made her feel bad about herself.

She turned in through a pair of stone pillars and wrought-iron gates – easy to climb over – and keeping in the deep shadow of the high box hedge that surrounded the property, she ran swiftly through the rain toward the back of the house.

‘Lydia! You’re all wet.’ Polly’s blue eyes were wide and startled, but her face was still soft with the mists of sleep.

‘Sorry to wake you. I just had to come and tell you about…’

Polly was pulling at her, dragging the wet dress over Lydia’s head and shaking it out with a sorrowful little moan of displeasure. ‘I hope it’s not ruined.’

‘Oh Polly, never mind the dress. It got soaked when I wore it before but dried out fine. Well, almost fine. One or two water stains on the satin bit, that’s all, so a few more won’t hurt.’

Polly placed the dress with care on a hanger. ‘Here, wear this.’

She threw Lydia a dressing gown. It was white with small pink elephants round the hem and cuffs. Lydia thought it childish but put it on anyway to cover up her fleshless bones. Polly’s body was all soft and full of curves, her breasts already full and mobile, while Lydia’s were little more than upturned saucers. ‘When you get some food inside you, darling, they’ll fill out, don’t fret,’ her mother had told her. But Lydia wasn’t so sure.

Polly sat down on her bed and patted the spot beside her. ‘Sit down and tell all.’

That was one of the things Lydia loved about Polly. She was adaptable. She didn’t mind in the least being woken in the middle of the night by a rap at her window and was happy to throw it open to her drenched nocturnal visitor. It was a simple climb up to the second floor, one Lydia had often done before, up the trellis, across the veranda roof, and an easy jump up to the windowsill. Fortunately Christopher Mason was so besotted by his dogs that they were allowed to sleep in the scullery whenever it rained, so there was no risk of losing a chunk of leg to sharp teeth.

‘How did it go?’ Polly demanded, excitement making her face look younger than her sixteen years. ‘Did you like him?’

‘Like who?’

‘Alfred Parker. Who else? Isn’t that what you’ve come to tell me about?’

‘Oh yes. Yes, of course. The dinner at La Licorne.’

‘So what happened?’

Lydia had to search a long way back in her mind. ‘It was fun. I had prawns in garlic sauce,’ she breathed heavily into Polly’s face to offer proof, ‘and steak au poivre and…’

‘No, no. Not the food. What was he like?’

‘Mr Parker?’

‘Yes, silly.’

‘He was… kind.’ The word surprised Lydia, but when she thought about it she decided it was true.

‘How dull!’

‘Oh, yes, he’s as dull as a Latin lesson. He thinks he knows everything and wants you to think the same. I got the feeling he likes to be admired.’

Polly giggled. ‘Don’t be such a dunce, Lyd, all men love to be admired. It’s what they’re about.’

‘Really?’

‘Yes, really. Haven’t you noticed? That’s what your mother is so good at and why men flock round her.’

‘I thought it was because she’s beautiful.’

‘Being beautiful isn’t enough. You have to be smart.’ She shook her tousled blond hair with an affectionate smile. ‘My mother is absolutely useless at it.’

‘But I like your mother just as she is.’

Polly grinned. ‘So do I.’

‘Are your parents in bed?’

‘No, they’re out at some party at General Stowbridge’s place. They won’t be back for hours yet.’ Polly jumped off the bed. ‘Nobody’s here except the servants, but they’re off in their own quarters, so shall we go down and make some cocoa?’

Lydia leaped at the offer. ‘Yes, please.’

They hurried out of the room, down the stairs, and into the kitchen. Lydia felt more comfortable here. If she was honest with herself, she didn’t actually like Polly’s bedroom; it made her tense. It was Polly’s behaviour in it that unsettled her. Lydia had quickly learned to touch nothing. Absolutely nothing. If she picked up a hairbrush from the dressing table or a book from the bookcase, Polly got all twitchy and rushed to put it back in exactly the right spot and at exactly the right angle. Worse were the dolls. She had a whole row of twenty-three beautiful dolls lined up on a shelf, with china faces and hand-embroidered dresses. If any of them moved as much as a finger or a lock of hair, Polly noticed and felt compelled to strip the whole shelf and set them up again. It took forever.

Lydia steered well clear of them. The odd thing was that these weird obsessions fell away as soon as Polly left her room, and her desk at school was far more scatterbrained than Lydia’s own. It was as if in the privacy of her own room she could indulge her anxieties and fears, but elsewhere she hid them away and smiled at the world. Lydia was always careful to make sure no one upset Polly, not even Mr Theo.

‘I’ll just go and check on Toby,’ Polly said. ‘Won’t be long.’ She disappeared into the scullery.

Lydia wandered into the hall, sliding her feet along the polished floor till they squeaked, and peeked into the drawing room just to catch a glimpse of the gramophone and its shiny brass horn in the hope that their aroma of luxury would drag her mind away from Chang. But they only made her feel worse. Next to the drawing room was the door to Polly’s father’s study, which was always kept firmly shut. For the hell of it, Lydia tried the handle. It turned.

The room was dark, but she didn’t dare turn the light on. A bright yellow rectangle tumbled into the study from the doorway and lay across the big oak desk that sat squarely in the middle of the floor with a row of dark wooden filing cabinets behind it. On the wall opposite was a painting of a tall grey horse with one black hoof and beside it a portrait in oils of a nervous-looking young boy. Presumably Christopher Mason in earlier days. But Lydia’s attention was not on the walls. It was on a large leather-bound book that lay on the desktop. With a rapid glance over her shoulder to see if Polly was anywhere near, she stepped into the gloomy room and leaned over the book. On its tan cover was the one word in gold-embossed letters. DIARY. She opened it. Quickly she flicked through until she came to the page that showed the date of the concert, July the fourteenth, Saturday.

His writing was large and hurried, a scribble of black ink that was difficult to read, but she made out enough. Six a.m. – riding with Timberley. Eight-thirty – breakfast meeting with Sir Edward at the Residence. Below it was something written in and scratched out again by heavy black lines followed by Tiffin with MacKenzie and then Willoughby 7:30. Finally, written in small letters at the bottom of the page, was V.I. at Club. It was underlined.

V.I.

Valentina Ivanova.

So the meeting had not been accidental.

‘Lydia?’ Polly’s voice from the kitchen.

‘Coming,’ Lydia called out. She skimmed through the previous pages. V.I. V.I. V.I. V.I. V.I. V.I. One in each month. From January to July. She flicked ahead. One scheduled for August the eighteenth.
