No end to evil really. What could you do? You could start with one small kid.

1974: New Year’s Eve

A black-tie dinner-dance in the Metropole. It was in aid of some charity for kiddies – the sick or the deaf or the blind. Ray Strickland hadn’t taken much notice, just knew it was expensive. ‘Charity begins at home,’ his wife, Margaret, said. Ray wasn’t entirely sure he knew what that meant. His wife was a kind person. ‘Daughter of the manse,’ she said. ‘I was brought up to believe that you have a duty to help the less fortunate.’ ‘That would be me then,’ Ray joked.

Margaret was from Aberdeen originally. They had met one night ten years ago, in the A and E, when Ray was still in uniform, interviewing a drunk who’d been in a fight. She had come down to do her nurse’s training at St James’s, wanting ‘to see England’. Ray told her that there was more to England than Leeds although at the time he hadn’t been further afield than Manchester. Before she met him Margaret had had plans to become a missionary in some farflung dark corner of the world. Then they became engaged and that was it, he became her mission, her own dark corner of the world.

When they were courting, he used to meet her off her shift and they would pop across the road to the old Cemetery Tavern and have a drink. Long time now since that was pulled down. Half of Tetley’s mild for Ray, lemonade shandy for Margaret, daring for her at the time – she’d been raised in abstinence. So had Ray, of course, a West Yorkshire Wesleyan, signed the pledge and everything when he was younger. The pledge broken long ago.

In another life Margaret would have been a saint or a martyr. Not in a bad way, not in the way that other men he knew said of their wives, ‘Thinks she’s a bloody saint, she does.’ Or, ‘She’s a martyr to the housework.’ Ray valued her goodness. Hoped in some way it would rub off on him. He came to the end of every day feeling as if he had failed somehow. ‘Don’t be silly,’ Margaret said. ‘You make the world a better place, even if it’s only in a small way.’ Her faith in him was faulty. He lived his life in a state of guilt, every day waiting to be found out. He wasn’t even sure what it was he had done.

He looked around the room for Margaret and couldn’t see her anywhere.

Bigwigs. Magistrates, businessmen, solicitors, councillors, doctors, police, lots of police. The great and the good out in force to say farewell to the old year. The air was soupy – cigars, cigarettes, alcohol, perfume, all mixed with the smell of the remains of the buffet. Seafood cocktail, plates of ham and chicken and curried eggs, potato salad, bowls of trifle. It was making him feel sick. His chief superintendent, Walter Eastman, had been plying him with malts. They were all hard drinkers – Eastman, Rex Marshall, Len Lomax. ‘You’re one of us, lad,’ Eastman said, ‘so ruddy well drink like one of us.’ Ray wasn’t sure who ‘us’ was. Freemasons, police, members of the golf club? Perhaps he just meant men as opposed to women.

‘You’re on the up, Strickland,’ Eastman said. ‘DC now but you’ll be an inspector before you know it.’

Lots of bigwigs here in the room, of course. That was why Ray – selfconscious in the penguin suit that he’d had to hire from Moss Bros – was here. Eastman had persuaded him to buy the tickets. ‘It’ll be good for you, lad, t’rub shoulders with your elders and betters.’ Eastman, he was Eastman’s protégé. ‘That’s good,’ Margaret said. ‘Isn’t it?’

The women were all dressed up to the nines, satin and rhinestones – cajoling husbands and fiancés out on to the dance floor, where they grumbled their way around, doing inept foxtrots and stumbling quicksteps, desperate to get back to their fags and pints. Eastman was proud of his waltz, he was light on his feet for such a heavy bloke. He had insisted on taking Margaret ‘for a turn’ round the dance floor.

‘Your wife’s a nice woman,’ he said.

‘I know.’ Ray followed Eastman’s gaze and caught a glimpse of Margaret at the far side of the room. She was wearing her midnightblue lace and her soft hair was freshly set in concrete curls. She was thirty but the sixties had never happened for her. She looked very demure compared to some of the flesh on show, mutton dressed as lamb. Margaret was the other way round, lamb dressed as mutton. Ray admired modesty in a woman. His mother was his ideal wife but she would never have married someone as movable as Ray. No fixed foot, that was his trouble. ‘Stop doing yourself down, Ray,’ Margaret said, spooning his cold, worried back in the barren acreage of the marriage bed.

She was sitting at a table with Kitty Winfield, their heads close together as if they were sharing secrets. They made an odd pair. Kitty Winfield in black velvet, pearls around her neck, long hair sculpted up into a sophisticated do. The only woman in the room who knew that less was more. Everyone aware she used to be a model. Kitty Gillespie, as she had been in those days. They all presumed she had a racy past, she had dated famous people, she had been in the papers, she was one of the first to wear a miniskirt, but now she was pure class. Women wanted to be her friend, men held her in awe, beyond reproach, almost beyond lust. If Margaret was a saint, Kitty Winfield was a goddess. ‘She walks in beauty,’ Eastman murmured at Ray’s side. Eastman was a big golfing pal of Kitty Winfield’s husband, Ian. Margaret worked alongside Ian Winfield at the hospital. Margaret looked like a different species sitting next to Kitty. A dowdy pigeon next to a swan. ‘Kitty,’ Eastman said. ‘So fragile.’ Ray understood that was a polite word for neurotic.

Ray knew what bonded Margaret and Kitty Winfield. Fertility. Or lack of it. Kitty Winfield couldn’t conceive a baby, Margaret couldn’t keep one inside. Margaret had endured three miscarriages, one premature stillbirth. Last year the doctors told her that she couldn’t try for any more, something wrong inside her. Sobbing all the way home from the hospital.

She had spent years doing all this knitting, little lacy things in pastel colours. ‘Have to have something on the needles,’ she said. Cupboards full of baby clothes. Sad. Now she knitted for ‘babies in Africa’. Ray wasn’t sure that African kiddies would appreciate wearing wool but didn’t say anything.

‘We can adopt,’ he had said on that last dreadful car journey home from the hospital. That made her cry even more.

He excused himself to Eastman and made his way round the dance floor to where Margaret and Kitty Winfield were sitting. Tragedy of it was, of course, that Margaret was a nurse on the kiddies’ ward, spent all day with other women’s children. And – an irony this as well – Kitty Winfield’s husband was a kiddy doctor. Paediatrician at St James’s.

Until recently they hadn’t mixed in the same social circles. The Winfields were part of a cocktail crowd, big house in Harrogate. ‘Cosmopolitan,’ Margaret said. ‘Big word,’ Ray said. Now it was all different. Margaret always ‘popping over’ to see Kitty Winfield. ‘She understands what it feels like not to be able to have a baby,’ Margaret said.

‘I understand,’ Ray said.

‘Do you?’

‘Why don’t we adopt?’ Ray tried again. Margaret was more amenable to the idea this time. A nurse and a policeman, churchgoers, fit as fleas, surely they would be the ideal couple in an adoption agency’s eyes?

‘Maybe,’ Margaret said.

‘Not African kiddies, mind,’ Ray said. ‘No need to go that far.’

Before Christmas they had been invited to a party at the Winfields’ Harrogate house. Margaret had fussed about what to wear, in the end decided on the midnight-blue lace again. ‘For God’s sake,’ Ray said, ‘buy yourself something new.’

‘But this is perfectly good,’ she said, so he was surprised when she came downstairs wearing a black sleeveless dress. ‘Little black dress,’ she said. ‘Kitty gave it to me. We’re the same size.’ You would never have thought that to look at them, not in a million years.
