'You talked about her reading a voice-over: he said.

'I wondered if there might be a script:

'Of course!' Euan was more animated than he'd been all day. 'The thief might not have thought of that. I'll look, shall I?'

'Shall I help?'

'No, Inspector. If you don't mind this is something

I'd rather take care of alone!

In the hall they stood for a moment. Perez put on his coat and prepared to go out. Euan reached out awkwardly and shook his hand 'Thank you for taking me seriously, Inspector. Since Fran Hunter found her body, I've been searching for an explanation for Catherine's death. The discovery of Catriona's body on the hill provided one of a sort. Not a very satisfactory one. A madman who enjoys inflicting violence on young girls. It's not something I can make sense of. Too random. Too arbitrary. It seems to me that the missing film could provide another explanation. If Catherine had filmed something which the murderer would rather keep hidden, that might provide a motive. But perhaps I'm deluding myself. Perhaps I'm going mad too!

He opened the door and held it wide for Perez to pass through. Walking down the path to his car, Perez remembered a conversation he'd had with Magnus early on in the investigation. Magnus had said Catherine had taken his photo on the day she'd come to tea. The day after the party at the Haa. Perhaps it wasn't a photo. Perhaps she'd wanted Magnus to be in her film.

Chapter Thirty-Two

When Jimmy Perez got to the police station the next day, he saw most of the Inverness boys had gone but Taylor was still there. Perez could hear him as he walked up the stairs. He'd taken over a desk in the Incident Room and was sitting at it, the chair tilted back, his legs outstretched, shouting into the phone. He was the only person in the room, which had an empty, leftover feel about it, like the Northlink ferry once the passengers had disembarked.

There were scraps of rubbish on the floor, used polystyrene cups on the desks. It was mid-morning and outside the sun was trying to get through. 'Two gulls perched on a nearby roof were screaming at each other.

Perez stood, waiting, until Taylor replaced the receiver.

'They want me to sign off the case and go back to Inverness. I can't. I'm not satisfied Tait killed Catherine, certainly not sure we'll get a conviction. There's nothing forensic to link him with her. They weren't even killed in the same way!

'Circumstantial though. 'Two girls murdered in the same place..!

'I've told them I'm staying. If they push it I'll take a few days' leave! He looked up, grinned. 'I've always wanted to be here for Up Helly Aa!

'It's a show for the tourists,' Perez said. 'An excuse to get drunk:

'It's an excuse not to go south just yet:

Perez wondered again if Taylor had anyone to go home to. Maybe after a couple of beers he'd pluck up the courage to ask. 'There is something else..: He began explaining about his visit to Euan's house, the missing film and immediately he sensed Taylor’s scepticism. 'It could be a motive,' Perez said, wondering why it mattered to him so much. 'Perhaps the girl filmed something she wasn't supposed to see:

'Is the guy sure it's not there?' Taylor rocked forward so the chair was firm on the ground. 'I mean he must be upset. It'd be easy to overlook:

Perez shrugged. 'He seemed pretty positive. The camcorder's gone too. Magnus said Catherine took a picture of him the day before her body was found. Perhaps he talked to her about Catriona. It might be worth getting her computer south to the experts. See if there's some way of retrieving the deleted material: There was a silence then Taylor looked up suddenly from his desk. 'What do you think? Do you think Tait killed them both?'

Perez wanted to say it didn't matter what he thought. All that mattered was getting a conviction. But Taylor was still looking at him. 'I don't know,' he said at last. 'Really, I don't know: He could tell he'd disappointed Taylor with his answer and went on, feeling for the right words, 'I think I understand Catherine better now. After talking to her father. She was lonely. She saw life through film. That was how she survived here. That was how she got her pleasure, her kicks:

'A female voyeur?'

'An observer, a commentator! Perez paused, remembering what Duncan had said of her. 'A director!

'Doesn't a director make things happen? That's being more than an observer, surely!

'Perhaps she tried to make things happen. Perhaps that's why she was killed!

Celia Isbister lived in the house her husband Michael had built once he started making money. It was on the edge of Lerwick, with a view of the town and down to the sea. At the time of the wedding, gossip had it that he was a lucky man. He was marrying money. Certainly she'd carried with her an air of affluence. She'd been sent south to an expensive school. There was a big house on Unst. But the school had been paid for by a rich aunt and when their parents died, the big house went to her elder brother. There was nothing else to share out but debt.

If Michael had been disappointed by his new wife's poverty he hadn't blamed her for it. He'd carried through his life an astonishment that she'd ever agreed to marry him and took on the task of making himself worthy of her. He developed a transport and haulage business. When the oil came, his lorries carried cement and pipes and beer to the terminal at Sullom Voe and his taxis collected executives from Sumburgh Airport. If he knew of Celia's affair with Duncan – and surely he must have known – he never challenged her about it. She always stood at his side at civic functions. When he introduced her to visitors, to the ministers and civil servants who came occasionally from London and Edinburgh, he glowed with pride.

Celia had let Michael have his own way with the house. Perhaps it was a penance. Certainly, it couldn't have been to her taste. It was a sprawling ranch-style bungalow with an open-plan lounge. She only drew the line at gold taps for the ensuite bathrooms. Jimmy Perez wondered again what Robert had made of his parents' marriage. He moved in both their worlds. He was the youngest man on the Up Helly Aa committee and he went to the parties at the Haa. He must know that Celia's affair with Duncan was public knowledge. In Shetland information about other people's lives was assimilated subconsciously, a form of osmosis. For as long as Perez could remember people had been expecting Celia to leave Michael and to move into the Haa with Duncan Hunter.

But she still lived in the bungalow with her husband and Robert. Running these facts in his head, Perez thought he was stupid to believe that Catherine had been killed because she'd filmed some secret. So little in Shetland was secret. It was simply unacknowledged. There was something Victorian in this need to put on a good show.

He'd phoned beforehand to check that Celia would be in. She'd said she would be, all day. She didn't ask what he wanted from her. Perhaps she assumed he was there to speak on Duncan's behalf.

Celia was on her own in the bungalow.

'Michael not about?' Perez asked. He'd have liked to talk to Michael too.

She shook her head. 'He's in Brussels. Some European conference on fringe communities. Followed by a meeting in Barcelona on endangered dialect. He went on the third and won't be back until just before Up Helly Aa!

'She led Perez into the kitchen and started making coffee without asking first if he wanted any. He thought she seemed pale, distracted. She was a handsome woman, approaching fifty, with fine cheekbones, a generous mouth.

He understood what Duncan found attractive about her, caught himself watching her as she stretched to reach mugs from a high shelf.

' I don't suppose this is a social call: she said.

Of course not. I never called on you, even when Duncan was still my friend. You were a secret everyone knew about, but we couldn't acknowledge you.

'But it can't be about the dead girl. That's all over, isn't it?'
