All of which Rebus mercifully avoided. He had once made the mistake of making a sicker pun than Dr Curt, and as a result found himself in the doctor's favour. One day, he knew, Holmes would make a better pun yet, and then Curt would have himself a new pupil and confidant… So, skirting around the doctor, Rebus made for Lauderdale's office.

Lauderdale himself was just getting off the phone. When he saw Rebus, he turned stony. Rebus could guess why.

'I just sent someone round to Glass's bedsit.'

'And he's gone,' Rebus added.

'Yes,' Lauderdale said, his hand still on the receiver. 'Leaving little or nothing behind him.'

'Should be easy enough to pick him up, sir.'

'Get on to it, will you, John? He must still be in the city. What is it? – an hour since he left here. Probably somewhere in the Granton area.'

'We'll get out there right away, sir,' said Rebus, glad of this excuse for a little action.

'Oh, and John…?'

'Sir?'

'No need to look so smug, okay?'

So the day filled itself, evening coming upon him with surprising speed. But still they had not found William Glass. Not in Granton, Pilmuir, Newhaven, Inverleith, Canonmills, Leith, Davidson's Mains… Not on buses or in pubs, not by the shore, not in the Botanic Gardens, not in chip shops or wandering on playing fields. They had found no friends, no family, just bare details so far from the DHSS. And at the end of it all, Rebus knew, the man might be innocent. But for now he was their straw, to be clutched at. Not the most tasteful metaphor under the circumstances, but then, as Dr Curt himself might have said, it was all water under the bridge so far as the victim was concerned.

'Nothing, sir,' Rebus reported to Lauderdale at the end of play. It had been one of those days. Nothing was the sum total of Rebus's endeavours, yet he felt weary, bone and brain weary. So that he turned down Holmes' kindly offer of a drink, and didn't even debate over his destination. He headed for Oxford Terrace and the ministrations of Dr Patience Aitken, not forgetting Lucky the cat, the wolf-whistling budgies, the tropical fish, and the tame hedgehog he'd yet to see.

Rebus telephoned Gregor Jack's home first thing Wednesday morning. Jack sounded tired, having spent yesterday in Parliament and the evening at some 'grotesque function, and you can quote me on that'. There was a new and altogether fake heartiness about him, occasioned, Rebus didn't doubt, by the shared knowledge of the contents of that dustbin.

Well, Rebus was tired, too. The real difference between them was a question of pay scales… 'Have you heard anything from your wife yet, Mr Jack?'

'Nothing.'

There was that word again. Nothing. 'What about you, Inspector? Any news?'

'No, sir.'

'Well, no news is better than bad news, so they say. Speaking of which, I read this morning that that poor woman at Dean Bridge was murder.'

'I'm afraid so.'

'Puts my own troubles into perspective, doesn't it? Mind you, there's a constituency meeting this morning, so my troubles may just be starting. Let me know, won't you? If you hear anything, I mean.'

'Of course, Mr Jack.'

'Thank you, Inspector. Goodbye.'

'Goodbye, sir.'

All very formal and correct, as their relationship had to be. Not even room for a 'Good luck with the meeting'. He knew what the meeting would be about. People didn't like it when their MP got himself into a scandal. There would be questions. There would need to be answers…

Rebus opened his desk drawer and lifted out the list of Elizabeth Jack's friends, her 'circle'. Jamie Kilpatrick the antique dealer (and apparent black sheep of his titled family); the Hon. Matilda Merriman, notorious for her alleged night of non-stop rogering with a one-time cabinet member; Julian Kaymer, some sort of artist; Martin Inman, professional landowner; Louise Patterson-Scott, separated wife of the retail millionaire… The 'names' just kept on coming, most of them, as Jack himself had put it while making out the list, 'seasoned dissolutes and hangers-on'. Mainly old money, as Chris Kemp had said, and a long way away from Gregor Jack's own 'pack'. But there was one curio among them, one seeming exception. Even Rebus had recognized it as Gregor Jack scratched it on to the list.

'What? The Barney Byars.? The original dirty trucker?'

'The haulier, yes.'

'A bit out of place in that sort of company, isn't he?'

Jack had owned up. 'Actually, Barney's an old school-pal of mine. But as time's gone on, he's grown friendlier with Liz. It happens sometimes.'

'Still, somehow I can't see him fitting in with that lot -'

'You'd be surprised, Inspector Rebus. Believe me, you would be surprised.' Jack gave each word equal weight, leaving Rebus in no doubt that he meant what he said. Still… Byars was another fly Fifer, another famous son. While at school, he'd made his name as a hitchhiker, often claiming he'd spent the weekend in London without paying a penny to get there. After school, he made the news again by hitching his way across France, Italy, Germany, Spain. He'd fallen in love with the lorries themselves, with the whole business of them, so he'd saved, got his HGV licence, bought himself a lorry… and now was the largest independent haulier that Rebus could think of. Even on last year's trip to London, Rebus had been confronted by a Byars Haulage artic trying to steer its way through Piccadilly Circus.

Well, it was Rebus's job to ask if anyone had seen hide or hair of Liz Jack. He'd gladly let others do the hard work with the likes of Jamie Kilpatrick and the grim-sounding Julian Kaymer; but he was keeping Barney Byars for himself. Another week or two of this, he thought, and I'll have to buy an autograph book.

As it happened, Byars was in Edinburgh, 'drumming up custom', as the girl in his office put it. Rebus gave her his telephone number, and an hour later Byars himself called back. He would be busy all afternoon, and he'd to go to dinner that evening 'with a few fat bastards', but he could see Rebus for a drink at six if that was convenient. Rebus wondered which luxury hotel would be the base for their drink, and was stunned, perhaps even disappointed, when Byars named the Sutherland Bar, one of Rebus's own watering holes.

'Right you are,' he said. 'Six o'clock.', Which meant that the day stretched ahead of him. There was the Case of the Lifted Literature, of course. Well, he wasn't going to hold his breath waiting for a result there. They would turn up or they would not. His bet would be that by now they'd be on the other side of the Atlantic. Then there was William Glass, suspect in a murder inquiry, somewhere out there in a back close or a cobbled side street. Well, he'd turn up come giro day. If, that is, he was more stupid than so far he'd proved to be. No-, maybe he was full of cunning. In which case he wouldn't go near a DHSS office or back to his digs. In which case he would have to get money from somewhere.

So – go talk to the tramps, the city's dispossessed. Glass would steal, or else he would resort to begging. And where he begged, there would be others begging, too. Put his description about, maybe with a tenner as a reward, and let others do your work for you. Yes, it was definitely worth mentioning to Lauderdale. Except that Rebus didn't want to do the Chief Inspector too many good turns, otherwise Lauderdale would think he was currying favour.

'I'd rather curry an alsatian,' he said to himself.

With a nice sense of timing, Brian Holmes came into the office carrying a white paper bag and a polystyrene beaker.

'What've you got there?' Rebus asked, suddenly hungry.

'You're the policeman, you tell me.' Holmes produced a sandwich from the bag and held it in front of Rebus.

'Corned chuck Rebus guessed..,

'Wrong. Pastrami on rye bread.'

'What?'
