'You'd be surprised. Hard bastard, is he?'

'I'd say so.'

'Given you grief?' Matty shook his head. 'Do you see much of him?'

'Not much,' Matty said. Not, he might have added, ' until recently at any rate.

Rebus dropped him at the foot of Broughton Street, headed back up to Leith Walk and along York Place onto Queen Street. He passed the casino again and slowed, a frown on his face. At the next set of lights, he did a U-turn so he could be sure. Yes, it was the Roller from Gaitanos, no doubt about it.

Parked outside the Morvena.

'Mind if I join you?'

Rebus was eating breakfast in the canteen and wishing there was more caffeine in the coffee, or more coffee in the coffee come to that. He nodded to the empty chair and Siobhan sat down.

'Heavy night?' she said.

'Believe it or not, I was on orange juice.'

She bit into her muffin, washing it down with milk. 'Harry tells me you had him working a tape.'

'Harry?'

'Our video wizard. He said it was a missing person. News to me.'

'It's not official. The son of an old schoolfriend of mine.'

'Standing at a bar one minute and gone the next?' Rebus looked at her and she smiled. 'Harry's a great one for gossip.'

'I'm working on it in my own time.'

'Need any help?'

'Handy with a crystal ball, are you?' But Rebus dug into his pocket and brought out the still from the video. That's Damon there,' he said, pointing.

'Who's that with him?'

'I wish I knew. She's not with him. I don't know who she is.'

'You've asked around?'

'I was at the club last night. A few punters remembered her.'

'Male punters?' She waited till Rebus nodded. 'You were asking the wrong sex. Any man would have given her the once-over, but only superficially. A woman, on the other hand, would have seen her as competition. Have you never noticed women in nightclubs? They've got eyes like lasers. Plus, what if she visited the loo?'

Rebus was interested now. 'What if she did?'

'That's where women talk. Maybe someone spoke to her, maybe she said something back. Ears would have been listening.' Siobhan stared at the photo. 'Funny, it's almost like she's got an aura.'

'How do you mean?'

'Like she's shining.'

'Interior light.'

'Exactly.'

'No, that's what your friend Harry said. It's the interior lighting that gives that effect.'

'Maybe he didn't know what he was saying.'

'I'm not sure I know what you're saying.'

'Some religions believe in spirit guides. They're supposed to lead you to the next world.'

'You mean this one's not the end?'

She smiled. 'Depends on your religion.'

'Well, it's plenty enough for me.' He looked at the photo again. 'I was sort of joking, you know, about her being a spirit guide.'

'I know.'

He met with Helen Cousins that night. They spoke over a drink in the Auld Hoose. Rebus hadn't been in the place in quarter of a century, and there'd been changes. They'd installed a pool table.

'You weren't invited along that night?' Rebus asked her.

She shook her head. She was twenty, three years younger than Damon. The fingers of her right hand played with her engagement ring, rolling it, sliding it off over the knuckle and then back down again. She had short, lifeless brown hair, dark, tired eyes, and acne around her mouth.

'I was out with the girls. See, that was how we played it. One night a week the boys would go off on their own, and we'd go somewhere else. Then another night we'd all get together.'

'Do you know anyone who was at Gaitanos that night? Apart from Damon and his pals?'

She chewed her bottom lip while considering. The ring came off her finger and bounced once before hitting the floor. She stooped to pick it up.

'It's always doing that.'

'You better watch it, you're going to lose it.'

She pushed the ring back on. 'Yes,' she said, 'Corinne and Jacky were there.'

'Corinne and Jacky?' She nodded. 'Where can I find them?'

A phone call brought them to the Auld Hoose. Rebus got in the round: Bacardi and Coke for Corinne, Bacardi and blackcurrant for Jacky, a second vodka and orange for Helen and another bottle of no-alcohol lager for himself. He eyed the optics behind the bar. His mean little drink was costing more than a whisky. Something was telling him to indulge in a Teacher's. Maybe it's my spirit guide, he thought, dismissing the idea.

Corinne had long black hair crimped with curling tongs. Her pal Jacky was tiny, with dyed platinum hair. When he got back to the table, they were in a huddle, exchanging gossip. Rebus took out the photograph again.

'Look,' Corinne said, 'there's Damon.' So they all had a good look. Then Rebus touched his finger to the strapless aura.

'Remember her?'

Helen prickled visibly. 'Who is she?'

'Yeah, she was there,' Jacky said.

'Was she with anyone?'

'Didn't see her up dancing.'

'Isn't that why people go to clubs?'

'Well, it's one reason.' All three broke into a giggle.

'You didn't speak to her?'

'No.'

'Not even in the toilets?'

'I saw her in there,' Corinne said. 'She was doing her eyes.'

'Did she say anything?'

'She seemed sort of… stuck-up.'

'Snobby,' Jacky agreed.

Rebus tried to think of another question and couldn't. They ignored him for a while as they exchanged news. It was like they hadn't seen each other in a year. At one point, Helen got up to use the toilet. Rebus expected the other two to accompany her, but only Corinne did so. He sat with Jacky for a moment, then, for want of anything else to say, asked her what she thought of Damon. He meant about Damon disappearing, but she didn't take it that way.

'Ach, he's all right.'

'Just all right?'

'Well, you know, Damon's heart's in the right place, but he's a bit thick. A bit slow, I mean.'

'Really?' The impression Rebus had received from Damon's family had been of a genius in waiting. He suddenly realized just how superficial his own portrait of Damon was. Siobhan's words should have been warning – so far he'd heard only one side of Damon. 'Helen likes him though?'

'I suppose so.'

'They're engaged.'

'It happens, doesn't it? I've got friends who got engaged just so they could throw a party.' She looked around the bar, then leant towards him. 'They used to have some mega arguments.'

'What about?'

'Jealousy, I suppose. She'd see him notice someone, or he'd say she'd been letting some guy chat her up. Just the usual.' She turned the photo around so it faced her. 'She looks like a dream, doesn't she? I remember she was dressed to kill. Made the rest of us spit.'

'But you'd never seen her before?'

Jacky shook her head. No, no one seemed to have seen her before, nobody knew who she was. Unlikely then that she was local.

'Were there any buses in that night?'

'That doesn't happen at Gaitanos,' she told him. It's not "in" enough any more. There's a new place in Dunfermline. That gets the busloads.' Jacky tapped the photo. 'You think she's gone off with Damon?'

Rebus looked at her and saw behind the eyeliner to -a sharp intelligence. 'It's possible,' he said quietly.

'I don't think so,' she said. 'She wouldn't be interested, and he wouldn't have had the guts.'

On his way home, Rebus dropped into St Leonard 's. The amount he was paying in bridge tolls, he was thinking about a season ticket. There was a fax on his desk. He'd been promised it in the afternoon, but there'd been a delay. It identified the owner of the Rolls-Royce as a Mr Richard Mandelson, with an address in Juniper Green. Mr Mandelson had no criminal record outstanding, whether for motoring offences or anything else. Rebus tried to imagine some poor parking warden trying to give the Roller a ticket with the fat man behind the wheel. There were a few more facts about Mr Mandelson, including last known occupation. Casino manager.
