Which was why he had bought this house, just off Shirley Drive, that they really could not afford. It wasn’t big, but it was in one of the most expensive residential districts of Brighton and Hove, a tranquil, hilly area of detached houses with sizeable gardens along tree-lined streets. And because the house was modern, on split levels, it looked different from most of the more conventional Edwardian mock-Tudor houses that were the mainstay of the area; people did not realize it was actually quite small. The teak decking and bijou outdoor pool added a touch of Beverly Hills glamour.

It was 1.50 p.m. Nice that he had just called. Time zones always confused her; strange that he was having his breakfast and she was having her cottage cheese and berries lunch. She was happy that he was flying back tonight. She always missed him when he was away – and, knowing he was a womanizer, she always wondered what he got up to when he was on his own. But this was a short trip – just three days, not too bad.

This part of the garden was completely private, shielded from their neighbours by a tall trellis interwoven with mature ivy and a huge out-of-control rhododendron bush that seemed to have ambitions to be a tree. She watched the electronic pool sweeper cruising up and down the blue water, sending out ripples. Alfie, their tabby cat, seemed to have found something interesting at the back of the rhododendron and was walking slowly past, staring, then turning, walking slowly past again and staring some more.

You never knew what cats were thinking, she thought suddenly. Alfie was a bit like Ronnie, really.

She put her plate down on the ground and picked up the Daily Mail. She had an hour and a half before she needed to leave for the hairdresser. She was going to have highlights put in and then go to the nail studio. She always wanted to look nice for him.

Luxuriating in the warm rays of sun, she turned the pages. In a few minutes she would get up and iron his shirts. He might buy fake watches, but he always bought the real thing in shirts, and always from Jermyn Street, in London. He was obsessive about them being ironed properly. Now that the cleaning lady had gone, as part of their economy drive, she was having to do all the housework herself.

Smiling, she thought back to those early days with Ronnie, when she had actually liked doing his washing and ironing. Ten years ago, when they’d first met, when she’d been working as a sales demonstrator in duty free at Gatwick Airport, Ronnie had been putting back together the broken pieces of his life after his beautiful but brainless wife had run off to Los Angeles, to shack up with someone she’d met on a girls’ night out in London, a film director who was going to make her a star.

She remembered their first holiday, in a small rented flat outside Marbella, overlooking the yacht basin of Puerto Banus. Ronnie had drunk beer on the balcony, looking enviously down at the yachts, promising her that one day they’d own the biggest yacht in the harbour. And he knew how to romance a woman, all right. He was a master at it.

She had loved nothing better than to wash his clothes. To feel his T-shirts, swimming trunks, underwear, socks and handkerchiefs in her hands. To breathe in his manly smells on them. It was intensely satisfying to iron those beautiful shirts and then watch him wearing them, as if he was wearing part of herself.

Now it was a chore, and she found herself resenting his meanness.

She went back to the article on HRT she had been reading. The ongoing debate about whether the reduction of menopause symptoms – and the retention of youthful looks – outweighed the extra risks of breast cancer and other nasties. A wasp buzzed around her head and she flapped it away, then paused to stare down at her own chest. Two years away from forty and everything was starting to go south, except for her expensive breasts.

Lorraine was not a flawless, striking beauty, but she had always been, in Ronnie’s parlance, a looker. She owed her blonde hair to her Norwegian grandmother. Not that many years back, like a trillion other blondes around the globe, she had copied the now classic hairstyle of Diana, Princess of Wales, and on a couple of occasions she’d actually been asked if she was the Princess of Wales.

Now, she thought gloomily, I’m going to have to do something about the rest of my body.

Lying back in the chair, her stomach resembled a kangaroo’s pouch. It was like the stomach of women who had had several children, where the muscles had gone or the skin had been permanently stretched. And there were cellulite dimples all over the tops of her thighs.

All that disaster happening to her body despite (and to Ronnie’s chagrin at the cost) going to her personal trainer three times a week.

The wasp returned, buzzing around her head. ‘Fuck off,’ she said, flapping her hand at it again. ‘Go away.’

Then her phone rang. She leaned down and picked up the cordless handset. It was her sister, Mo, and her normally calm, cheerful voice sounded strangely agitated. ‘Have you got your telly on?’

‘No, I’m out in the garden,’ Lorraine replied.

‘Ronnie’s in New York, isn’t he?’

‘Yes – I just spoke to him. Why?’

‘Something terrible’s happened. It’s all over the news. A plane’s just crashed into the World Trade Center.’

The rain worsened, rattling down on the steel roof of the SOCO Scientific Support Branch van, sounding as hard as hailstones. The windows were opaque, to allow in light but keep out prying eyes. There was little light outside now, however, just the bleakness of wet dusk, stained the colour of rust from ten thousand city street lights.

Despite the large external dimensions of the long-wheelbase Transit, the seating area inside was cramped. Roy Grace, finishing a call on his mobile, chaired the meeting, the policy book he had retrieved from his go-bag open in front of him.

Squeezed around the table with him, in addition to Glenn Branson, were the Crime Scene Manager, a Police Search Adviser, an experienced SOCO, one of the two uniform scene guards and Joan Major, the forensic archaeologist Sussex Police regularly called in to help with identification of skeletons – and also to tell them whether the occasional bone found on building sites, or by children in woods, or dug up by gardeners, was human or animal.

It was chilly and damp inside the van and the air smelled strongly of synthetic vapours. Reels of plastic crime-scene tape were packed in one section of the fitted metal shelving, body bags in another, plus tenting materials and ground sheets, rope, flexes, hammers, saws, axes and plastic bottles of chemicals. There was something grim about these vehicles, Grace always felt. They were like caravans, but they never went to campsites, only to scenes of death or violent crimes.

It was 6.30 p.m.

‘Nadiuska isn’t available,’ he informed the newly assembled team, putting his mobile down.

‘Does that mean we’ve got Frazer?’ Glenn responded glumly.

‘Yes.’

Grace saw everyone’s faces fall. Nadiuska De Sancha was the Home Office pathologist everyone in Sussex CID preferred to work with. She was quick, interesting and fun – and good-looking, as an added bonus. By contrast, Frazer Theobald was dour and slow, although his work was meticulous.

‘But the real problem is that Frazer is finishing a PM up in Esher at the moment. The earliest he could get here is about 9 p.m.’

He caught Glenn’s eye. They both knew what that meant – an all-nighter.

Grace headed the first page of his policy book: PRE-SCENE BRIEFING. Friday 19 October. 6.30 p.m. On site. New England Quarter development.

‘Can I make a suggestion?’ Joan Major said.
