there.’

      ‘OK,’ said Cooper. ‘We’ll take a look in a minute. You can show me the exact spot.’

      Helen returned, accompanied by an exhausted PC Wragg.

      ‘Is it … any use?’ she asked.

      ‘We’ll see.’ Cooper took a polythene bag from his back pocket and carefully slid the trainer into it. ‘Would you wait here for a while, please? A senior officer will probably want to speak to you.’

      Helen nodded and looked at her grandfather, but his expression didn’t alter. His face was stony, like a man resigned to a period of necessary suffering.

      Cooper went back into the road and pulled out his personal radio to contact Edendale Divisional HQ, where he knew DI Hitchens would be waiting for a report. He held the polythene bag up to the light, staring at its contents while he waited for the message to be relayed.

      The trainer was a Reebok, size-five, slim-fit. And the brown stains on the toe looked very much like blood.

      The E Division Police Headquarters in Edendale had been new once, in the 1950s, and had even earned their architect a civic award. But in the CID room, fifty years of mouldering paperwork and half-smoked cigarettes and bad food had left their mark on the walls and their smell in the carpets. The Derbyshire Constabulary budget had recently stretched sufficiently to decorate the walls, replace the window frames, and install air conditioning in some of the offices. They had also replaced the old wooden desks with modern equivalents more in keeping with the computer equipment they carried.

      DC Diane Fry was reading the bulletins. She had started off by catching up with the fresh ones for the day, then had continued casting back over recent weeks. Her intention was to make herself familiar with all the current enquiries in the division. Although she had been in Edendale nearly two weeks, she still felt as new as the white glosswork that for some reason was refusing to dry properly on the outside wall near the window. All the windows on this side of the building looked down on Gate C and the back of the East Stand at Edendale Football Club, a team struggling in the lower reaches of one of the pyramid leagues.

      The priority problem of the moment was car crime at local tourist spots. From the weary tone of some of the memos Fry came across, it sounded as though it always was the priority problem in E Division at this time of year. Many thousands of visitors were drawn into the Peak District National Park during the summer, bringing with them what appeared to be their own crime wave, like the wake trailing behind a huge cruise liner. These visitors left their cars at remote spots, in makeshift car parks on rough ground, in abandoned quarries and on roadside verges. The cars were invariably full of cameras and binoculars and purses stuffed with cash and credit cards, and God knows what else. At the same time, travelling criminals from the big conurbations around Sheffield in the east and Manchester in the west were touring the Peak District looking for just such victims. A few minutes with an unattended vehicle and they were away back to their cities, leaving a trail of distraught visitors and ruined holidays.

      It presented an apparently insoluble problem. It was impossible to get the message across to the car owners, since they were a constantly changing flood – here one day, then moving on the next, to be replaced by another group of visitors. It was impossible for the police to keep surveillance on vulnerable sites with the resources available; it was feasible only to identify possible perpetrators and ask neighbouring forces to keep them under observation. It was called living in hope.

      Diane Fry looked across the room at DS Rennie. He was on the phone, and had been for some time. She couldn’t hear what he was saying, but she was fairly sure he hadn’t yet taken a single note with the ballpoint pen he was chewing. He was thick-shouldered and thick-necked, a veteran prop forward in the divisional rugby team, as she had learned from his conversation with one of the other DCs. She also knew that Rennie’s first name was David, and that he was married with two children in their early teens.

      She had soon become aware of his sly sideways appraisal, a slithering of the eyes towards her when he thought she wasn’t looking. She had observed this in the past to be a common tentative first manoeuvre towards a junior female colleague, designed to culminate in an office affair. Many men, of course, never got past this first sign – it was more an indication of hope than intention. But there were others who were more of a nuisance, and Fry couldn’t tell just yet which Rennie was. It was helpful, though, to have the early warning, so that she could decide on her own terms when the time was right to put him down. Affairs with colleagues were not on her agenda. Not at all.

      She could see Rennie was not making the effort to appear busy, even though there was a DCI somewhere in the building and liable to appear in the CID room at any moment.

      ‘Sarge?’ said Fry, when at last he put the phone down.

      Rennie looked round, as if surprised that she was still there. Then he smiled, contorting his face until it was almost a wink. His tie was something dark green, with a small gold crest, and his suit was a good cut for his heavy shoulders, but not recently cleaned. He pulled out a bar of his habitual chewing gum, which Fry had guessed might mean he was a reformed smoker.

      ‘What can I do for you, Diane?’

      ‘This project group looking at the auto crime figures.’

      ‘Yeah?’

      ‘I wondered if a check had been done on the computer. Matching up locations and timings. An analysis of MOs. We could set up a computer model.’

      ‘Ben Cooper usually does that,’ said Rennie. ‘You’d better not mess with the computer until you’ve asked him about it.’

      ‘A computer model could come up with a set of predictions, suggest target locations. It’s worth a try, Sarge.’

      ‘I told you, speak to Ben. They’ve got him out at Moorhay, but he should be back in the office later, thank God.’

      Fry had already heard Ben Cooper’s name several times during her first week in Edendale. Apparently he was some paragon of all the virtues who knew everything. DC Cooper knew the area like the back of his hand, they said. He knew all the local villains and even their families, they said. He knew how all the systems in the CID office worked, too. He knew exactly how to fill in the vast quantities of paperwork that baffled other detectives. Now, apparently, he was the only one who knew how to use the computers. But Diane Fry had an information technology qualification to her name, and she had done a course on intelligence data analysis at the National Crime Faculty in Bramshill. At the first opportunity, she would show them who knew how to use the computers around here.

      For now, though, she decided to try another tack.

      ‘Someone from the NCIS did a paper on this problem a few months ago. It was mentioned when I was at Bramshill.’

      ‘Really?’

      Rennie sounded uninterested.

      ‘The National Criminal Intelligence Service.’

      ‘I know what the NCIS is, thanks.’

      ‘I wondered if someone had researched it. I can’t see any mention in the paperwork. Maybe the project group have followed it through?’

      ‘I doubt it.’

      ‘I’ll look it up, if you like, Sarge.’

      Rennie looked sour, pulled at his tie, scrabbled about on his desk for a bit of paper and picked up the phone to dial another number.

      ‘Shall I, Sarge?’

      ‘Oh, if you like.’

      Fry made a note for herself in her notebook and asterisked it. Then she put the car crime reports aside and picked up that morning’s bulletin on the missing girl, Laura Vernon. She had already read it once and had memorized its admittedly sketchy details.

      Her
