The site had been surrounded by fields of ripening corn and her first view of Paul had been of him striding down the side of a field towards them. He’d been wearing a yellow T-shirt, slightly ripped at the neck. Because of the angle of the field she hadn’t been able to see his legs. He was a bull-necked, blunt northerner quite different from anyone she’d ever met before. None of her mother’s friends were so forthright or so rude. So this is what all the girls at school were going on about, she’d thought. Paul Berglund had become her obsession. Later, when she returned to London she lost her mind completely. She found herself unable to sleep. The events of the summer continued to haunt her. Images flashed into her head with the jagged brilliance of a drug-induced trip. Again she couldn’t bring herself to eat.

She’d been admitted to an enlightened NHS psychiatric hospital that ran a residential unit for teenagers. She supposed her mother had pulled strings to get her in. By that time she was hardly aware of what was happening. The stated cause of admission was the eating disorder, which had become the focus of her mother’s concern. An eating disorder was fashionable, almost commonplace among the children of the high-powered women with whom Gwen James worked. But quite simply, Hattie thought she’d been mad. She developed paranoia, heard voices again, this time loud, controlling, battering into her brain. She couldn’t trust anyone.

The unit had twenty-four beds and had an old-fashioned emphasis on talking and shared activity. They took pills too, of course, but the other treatments seemed just as important. The place was run by a nurse called Mark who was a little overweight, with a soft doughy face and thinning hair. Perhaps his unappealing appearance was part of his strategy. He was so sympathetic that if he’d been at all good-looking all the young women would have fallen in love with him. As it was they could treat him as a favourite uncle or adored older brother. Hattie had regarded the unit as her sanctuary. She still considered some of the other patients as her friends. She had few others.
