'Something happened in that bar,' Rebus repeated as he walked with Clarke back to the CID suite.

'So you said.'

'Cafferty was there for a reason. He's never squandered so much as a quid in his life, so what's he doing booked into one of the dearest hotels in town?'

'I doubt he'll tell us.'

'But his stay happens to coincide with the oligarchs.' She looked at him and he gave a shrug. 'Looked it up in the dictionary. Thought maybe it had to do with oil.'

'It means a small group of powerful people, right?' Clarke checked.

'Right,' Rebus confirmed.

'Thing is, John, we've also got this woman at the car park…'

'Cafferty could have put her there. He's owned a fair few brothels in his time.'

'Or she could be nothing to do with it. I'm going to have Hawes and Tibbet talk to the witnesses, see if the e-fit jogs any memories.

But meantime, there's a more pressing question – namely, what the hell are you doing ru

'I prefer “vendetta” to “stakeout”.' She seemed ready to say something but he held up his hand. 'I was outside his place last night, as it happens, and he was at home.'

'So?'

'So he's keeping a room at the Caledonian, but not spending much time there.' They had arrived at the door to CID. 'And that means he's up to something.' Rebus opened the door and went in.

Katie Glass had been given a mug of strong-looking tea and was studying it warily.

'DC Tibbet always does that,' Rebus warned her. 'If you want ta

'I might pass,' she said, placing the mug on the corner of a desk.

Rebus introduced himself and shook her hand. Clarke thanked her for coming in and asked if she'd found something.

'Early days,' Glass hedged.

'But…?' Rebus nudged, knowing there was more.

'We may have a source for the fire: small glass bottles filled with a chemical of some kind.'

'What kind of chemical?' Clarke asked, folding her arms. All three were standing, while Hawes and Tibbet listened in from behind their desks. Todd Goodyear was standing by one of the windows, staring out. Rebus wondered if he'd been tracking Cafferty's departure.

'Gone for analysis,' the fire inspector was saying. 'If I had to guess, I'd say maybe it was cleaning fluid of some kind.'

'Household cleaner?'

Glass shook her head. 'Bottles were too small. But this was a man who had a lot of tapes in his house…'

'Cassette cleaner,' Rebus stated. 'For wiping oxidation off the heads of the cassette decks.'

'Impressive,' Glass said.

'I used to have a thing about hi-fi.'

'Well, at least one of the bottles looks like someone had wadded some tissue into its neck. It was sitting in the midst of a pile of melted tape casings.'

'In the living room?'

Glass nodded.

'So you think it was deliberate?'

Now she shrugged. 'Thing is, if you wanted to kill someone in a fire, usually you'd go to town – slosh petrol around the place, that sort of thing. This was a couple of sheets of loo roll and a small bottle of something flammable.'

'I think I see what you're getting at,' Rebus told her. 'Maybe Riordan wasn't the target.' He paused to see if anyone would beat him to it. 'The tapes were,' he eventually explained.

The tapes?' Hawes asked, forehead creasing.

'Piled around the little home-made pyre.'

'Meaning what exactly?'

That Riordan had something somebody wanted.'

'Or something they didn't want anyone else to have,' Clarke added, ru

Glass gave another shrug. 'Most of the tape itself is done to a crisp. Some of the casings fared a little better.'

'So there could still be writing on them?'

'It's possible,' Glass conceded. 'We've got a slew of stuff that the fire didn't quite get to – du

Rebus caught Siobhan Clarke's eye. 'Right up Ray Duffs street,'

he said.

Goodyear had turned away from the window and was trying to catch up. 'Who's Ray Duff?'

'Forensics,' Clarke explained. But she was focusing on Rebus.

'How about the engineer at Riordan's studio? He might be able to help.'

'Could have kept back-ups,' Tibbet piped up.

'So,' Glass said, folding her arms, 'do I send the stuff here, or to forensics, or the dead man's studio? Whatever the answer, I'll have to keep your D Division colleagues in the loop.'

Rebus thought for a moment, then puffed out his cheeks, exhaled noisily, and said: 'DS Clarke's in charge.'

Freddie the barman was on duty again. Rebus had spent a few minutes outside the Caledonian Hotel, smoking a cigarette and watching the choreography of passing traffic. Two taxis were parked in the cab rank, the drivers chatting to one another. The Caledonian's liveried doorman was giving directions to a couple of tourists. The elaborate clock at the corner of Fraser's department store was being photographed, presumably by another tourist.

There never seemed to be enough rooms in Edinburgh for these visitors; new hotels were always being proposed, considered and constructed. He could think of five or six off the top of his head, all opening within the past ten years, and with more to come. It gave the impression of Edinburgh as a boomtown. More people than ever seemed to want to work there, or visit, or do business.

The Parliament had brought plenty of opportunities. Some argued that independence would spoil things, others that it would build on the success while dealing with devolution's failings. It interested

him that a hard-nosed executive like Stuart Ja

He finished the cigarette and headed indoors, sliding on to one of the bar stools and offering Freddie a reasonably hearty 'good afternoon'. For a couple of seconds, Freddie mistook him for a guest -he knew the face, after all. He placed a coaster in front of Rebus and asked what he was having.

'The usual,' Rebus teased, enjoying the barman's confusion. Then he shook his head. 'I'm the cop from Friday. But I'll take a dram with a spot of water in it, so long as it's on the house.'

The young man hesitated, but eventually turned to the array of spirits bottles.

'A malt, mind,' Rebus warned him. There was no one else in the bar, no one at all. 'Bit of a graveyard, this time of day.'

'I'm on a double shift – the quiet suits me fine.'

The, too. Means we can talk that bit more freely.'

'Talk?'

'We've got the bar tabs from the night that Russian came in.

Remember? He sat right here, and one of your guests bought him a cognac. Guest's name is Morris Gerald Cafferty.'

Freddie placed the whisky in front of Rebus, and filled a small glass jug with tap water. Rebus dribbled some into the malt and thanked the barman.

Tou'll know Mr Cafferty?' he persisted. 'Last time we spoke, you pretended you didn't. Might explain why you tried pulling a flanker, telling me Todorov could've been talking Russian to the man who bought him the drink. Can't say I blame you, Freddie -Cafferty's not a man you'd want to get on the wrong side of.' He paused. 'Problem is, same goes for me.'

'I was confused, that's all – it was a busy night. Joseph Bo
