She didn’t know Linda well, had only met her once and hadn’t really talked with her much. But the local hippie community was small enough that if you hung around the right places for long enough, you’d come across pretty much everyone in the scene eventually, whether at the Grove, the Adelphi, the Peel or one of the student pubs on Woodhouse Lane, in Hyde Park or Headingley. Even as far away as the Farmer’s Inn, where they had blues bands like Savoy Brown, Chicken Shack, Free and Jethro Tull on a Sunday night. You could also be damn sure that they’d all beg, borrow or steal to get to an event with a lineup like the Brimleigh Festival. So, when you thought about it, Linda being there wasn’t quite so much a coincidence as it appeared on the surface. The thing was, you didn’t expect to get killed there; it was supposed to be a peaceful event, a gathering of the tribes and a celebration of unity.

The bus lumbered down Tong Road, past the Lyric, which was advertising a double bill of last year’s Carry On Up the Khyber and Carry On Camping. What crap, Yvonne thought. It was a gray day, and light rain pattered against the windows. Rows of grim back-to-back terraces sloped up the hill toward Hall Lane, all dark slate roofs and dirty red brick. A couple of kids got on at the junction with Wellington Road, behind the Crown, by the flats, and took the other front seat.

They’d filmed part of Billy Liar there a few years ago, Yvonne remembered, while it was a wasteland of demolished houses before the flats were built. Yvonne had been about eight, and her father had brought her down to watch. She had ended up in one of the crowd scenes waving a little flag as Tom Courtenay drove through in his tank, but when she had watched the film, she couldn’t see herself anywhere.

The kids lit cigarettes, kept looking over at her and making cheeky remarks. Yvonne ignored them.

She had met Linda at Bayswater Terrace one evening during the summer holidays. She had got the impression that it was just a flying visit, that Linda used to live there for a while but had moved to London. Linda was really fantastic, she remembered. She actually knew some of the bands and hung around with lots of rock stars at clubs and other “in” places. She wasn’t a groupie – she made that clear – she just liked the music and the guys who played it. Yvonne remembered someone saying that one of the members of the Mad Hatters was Linda’s cousin, but she couldn’t remember which one.

Linda even played a bit of guitar herself. She had sat down that evening with an acoustic and played “As Tears Go By” and “Both Sides Now.” Not a bad voice, either, Yvonne had thought, a little in awe of her and that sort of luminous haze her long blond hair and the long white dress she wore created around her pale features. The guys were all in love with her, you could tell, but she wasn’t interested in any of them. Linda didn’t belong to anyone. She was her own person. She also had a great throaty laugh, which surprised Yvonne, coming from one who looked so demure, like Marianne Faithfull.

McGarrity had been there that night, Yvonne remembered, and even he had seemed subdued, keeping his knife in his pocket for once and refraining from muttering T. S. Eliot all evening. The guy they said was organizing the Brimleigh Festival, Rick Hayes, had also been present, which was how they managed to score some free tickets. He knew Linda from down in London and seemed to know Dennis, too, whose house it was. Yvonne hadn’t liked Hayes. He had tried to get her to go upstairs with him and got a bit stroppy when she wouldn’t.

That was the only time Yvonne and Linda had met, and they hadn’t talked much, but Linda had made an impression. Yvonne was waiting for her O-level results, and Linda had said something about exams not proving anything and the real truth of what you were was inside you. That made sense to Yvonne. Now Linda was dead. Stabbed. Yvonne felt tears prick her eyes. She could hardly believe it. One of her own. She hadn’t seen her during the festival, but that wasn’t surprising.

The bus carried on past the gasworks, over the canal and river and past the huge building site where they were putting up the new Yorkshire Post building at the corner of Wellington Street, then past the dark, high Victorian buildings to City Square, where Yvonne got off. There were a couple of new boutiques she wanted to visit and that little record shop down the ginnel off Albion Street might still have a copy of the Blind Faith LP. Her parents hadn’t let her go to the free concert in London’s Hyde Park last June, but at least she could enjoy the music on record. Later she was going over to Carberry Place to meet up with Steve and have a few tokes. A bunch of them were going to the Peel that night to see Jan Dukes de Grey. Derek and Mick were quite the local celebrities and they were like real people; they’d talk to you and sign their first LP cover, Sorcerers, not hide away backstage like rock stars.

Yvonne’s problem persisted, though: whether or not to tell her father about Linda. If she did, the police would be at Bayswater Terrace like a shot. Maybe Dennis and Martin and Julie and the others would get busted. And it would be her fault. If they found out, they’d never speak to her again. She was sure that none of them could have had anything to do with what happened to Linda, so why bring grief on them? Rick Hayes was a creep and McGarrity was weird, but neither of them would kill one of their own. How could knowing about Linda being at Bayswater Terrace in July possibly help the police investigation? Her father would find out who Linda was eventually – he was good at finding things out – but it wouldn’t be from her, and nobody would be able to blame her for what happened.

That was what she decided in the end, turning the corner into the wet cobbled ginnel; she would keep it to herself. There was no way she was going to the pigs, even if the chief pig was her father.

There were some advantages to being a DCI, Banks thought on Sunday morning as he lingered over a second cup of coffee in the conservatory and read his way through the Sunday papers. Outside, the wind had dropped over the past couple of hours, the sun was shining and the weather had turned a little milder, though there was an unmistakable edge of autumn in the air – the smell of the musty leaves and a whiff of acrid smoke from a distant peat fire.

He was still senior investigating officer, of course, and in a short while he would go to interview Calvin Soames. At some point he would also drop by at the station and the incident van to make his presence felt and get up-to-date with developments, if there were any. In an investigation like this, he could never be far away from the action for any length of time, but the team had enough to occupy itself for the moment, and the SOCOs had plenty of trace evidence to sift through. He was always only a phone call away, so barring a major breakthrough, there was no reason for him to appear at the office at the crack of dawn every day; he would only get lumbered with paperwork. First thing tomorrow morning, he and Annie would be on the train to London, and perhaps there they would find out more about Nick Barber. All Annie had been able to find out on Google was that he had written for MOJO magazine and had penned a couple of quickie rock star biographies. It was interesting, and Banks thought he recognized the name now he saw it in context, but it still wasn’t much to go on.

Just as Banks thought it was time to tidy up and set off for Soames’s farm, he heard a knock at the door. It couldn’t be Annie, he thought, because she had gone to see Nick Barber’s parents near Sheffield. Puzzled, he ambled through to the front room and answered it. He was stunned to see his son, Brian, standing there.
