Lose a Fanner, gain a Fart.

The nickname had perhaps been unavoidable. Word association. Lauderdale became Fort Lauderdale, and Fort quickly; turned into Fart. Oh, but it was an apt name, too. For wherever Chief Inspector Lauderdale went, he left a bad smell. Take the Case of the Lifted Literature. Rebus had known the minute Lauderdale walked into his office that there would soon be a need to open the windows.

'I want you to stick close to this one, John. Professor Costello is highly thought of, an international figure in this field

'And?'

'And,' Lauderdale tried to look as though his next utterance meant nothing to him, 'he's a close personal friend of Chief Superintendent Watson.'

'Ah.'

'What is this – Monosyllable Week?'

'Monosyllable?' Rebus frowned. 'Sorry, sir, I'll have to ask DS Holmes what that means.'

'Don't try to be funny -'

'I'm not, sir, honest. It's just that DS Holmes has had the benefit of a university education. Well… five months' worth or thereabouts. He'd be the very man to coordinate the officers working on this highly sensitive case.'

Lauderdale stared at the seated figure for what seemed – to ' Rebus at least – a very long time. God, was the man really that stupid? Did no one appreciate irony these days?

'Look,' Lauderdale said at last, 'I need someone a bit more senior than a recently promoted DS. And I'm sorry to say that you, Inspector, God help us all, are that bit more senior.'

'You're flattering me, sir.'

A file landed with a dull thud on Rebus's desk. The chief inspector turned and left. Rebus rose from his chair and turned to his sash window, tugging at it with all his might. But the thing was stuck tight. There was no escape. With a sigh, he turned back and sat down at his desk. Then he opened the folder.

It was a straightforward case of theft. Professor James Aloysius Costello was Professor of Divinity at the University of Edinburgh. One day someone had walked into his office, then walked out again taking with them several rare books. Priceless, according to the Professor, though not to the city's various booksellers and auction rooms. The list seemed eclectic: an early edition of Knox's Treatise on Predestination, a couple of Sir Walter Scott first editions, Swedenborg's Wisdom of Angels, a signed early edition of Tristram Shandy, and editions of Montaigne and Voltaire.

None of which meant much to Rebus until he saw the estimates at auction, provided by one of the George Street auction houses. The question then was: what were they doing in an unlocked office in the first place?

'To be read,' answered Professor Costello blithely. 'To be enjoyed, admired. What good would they be locked up in a safe or in some old library display case?'

'Did anyone else know about them? I mean, about how valuable they are?'

The Professor shrugged. I had thought, Inspector, that I was amongst friends.'

He had a voice like a peat bog and eyes that gleamed like crystal. A Dublin education, but a life spent, as he put it, 'cloistered' in the likes of Cambridge, Oxford, St Andrews, and now Edinburgh. A life spent collecting books, too. Those left in his office – still kept unlocked – were worth at least as much as the stolen volumes, perhaps more.

'They say lightning never strikes twice,' he assured Rebus.

'Maybe not, but villains do. Try to lock your door when you step out, eh, sir? If nothing else.'

The Professor had shrugged. Was this, Rebus wondered, a kind of stoicism? He felt nervous sitting there in the office in Buccleuch Place. For one thing, he was a kind of Christian himself, and would have liked to be able to talk the subject through with this wise-seeming man. Wise? Well, perhaps not worldly-wise, not wise enough to know how snib locks and human minds worked, but wise in other ways. But Rebus was nervous, too, because he knew himself for a clever man who could have been cleverer, given the breaks. He had never gone to university, and never would. He wondered how different he would be if he had or could…

The Professor was staring out of his window, down on to the cobblestoned street. On one side of Buccleuch Place sat a row of neat tenements, owned by the university and used by various departments. The Professor called it Botany Bay. And across the road uglier shapes reared up, the modern stone mausoleums of the main university complex. If this side of the road was Botany Bay, Rebus was all for transportation.

He left the Professor to his muses and musings. Had the books been filched at random? Or was this designer theft, the thief stealing to order? There might well be unscrupulous collectors who would pay – no questions asked – for an early Tristram Shandy. Though the authors' names had rung bells, only that particular title had meant anything to Rebus. He owned a paperback copy of the book, bought at a car-boot sale on The Meadows for tenpence. Maybe the Professor would like to borrow it…

And so the Case of the Lifted Literature had, for Inspector John Rebus, begun. The ground had been covered before, as the case-notes showed, but it could be covered again. There were the auction houses, the bookshops, the private collectors… all to be talked to. And all to satisfy an unlikely friendship between a police chief superintendent and a professor of Divinity. A waste of time, of course. The books had disappeared the previous Tuesday. It was now Saturday, and they would doubtless be under lock and key in some dark and secret corner.

What a way to spend a Saturday. Actually, if the time had been his own, this would have been a nice afternoon, which was perhaps why he hadn't balked at the task. Rebus collected books. Well, that was putting it strongly. He bought books. Bought more of them than he had time to read, attracted by this cover or that title or the fact that he'd heard good things about the author. No, on second thoughts it was just as well these were business calls he was making, otherwise he'd be bankrupting himself in record time.

In any case, he didn't have books on his mind. He kept thinking about a certain MP. Was Gregor Jack married? Rebus thought so. Hadn't there been some big society wedding several years previous? Well, married men were bread and butter to prostitutes. They just gobbled them up. Shame though, about Jack. Rebus had always respected the man -which was to say, now that he thought about it, that he'd been taken in by Jack's public image. But it wasn't all image, was it? Jack really had come from a working-class background, had clawed his way upwards, and was a good MP. North and South Esk was difficult territory, part mining villages, part country homes. Jack seemed to glide easily between the two hemispheres. He'd managed to get an ugly new road rerouted well away from his well-heeled constituents, but had also fought hard to bring new high-tech industry to the area, retraining the miners so that they could do the jobs.

Too good to be true. Too bloody good to be true…

Bookshops. He had to keep his mind on bookshops. There were only a few to check, the ones that had not been open earlier in the week. Footwork really, the stuff he should have been doling out to more junior men. But all that meant was that he'd feel bound to come round after them, double checking what they'd done. This way, he saved himself some grief.

Buccleuch Street was an odd mixture of grimy junk shops and bright vegetarian takeaways. Student turf. Not far from Rebus's own flat, yet he seldom ventured into this part of town. Only on business. Only ever on business.

Ah, this was it. Suey Books. And for once the shop looked to be open. Even in the spring sunshine there was a need for a light inside. It was a tiny shop, boasting an unenthusiastic window display of old hardbacks, mostly with a Scottish theme. An enormous black cat had made a home for itself in the centre of the display, and blinked slowly if malignly up at Rebus. The window itself needed washing. You couldn't make out the titles of the books without pressing your nose to the glass, and this was made difficult by the presence of an old black bicycle resting against the front of the shop. Rebus pushed open the door. If anything, the shop's interior was less pristine than its exterior. There was a bristle-mat just inside the door. Rebus made a note to wipe his feet before he went back into the street…
