The shelves, a few of them glass-fronted, were crammed, and the smell was of old relatives' houses, of attics and the insides of school desks. The aisles were narrow. Hardly enough room to swing a… There was a thump somewhere behind him, and he feared one of the books had fallen, but when he turned he saw that it was the cat. It swerved past him and made for the desk situated to the rear of the shop, the desk with a bare lightbulb dangling above it.

'Anything in particular you're looking for?'

She was seated at the desk, a pile of books in front of her. She held a pencil in one hand and appeared to be writing prices on the inside leaves of the books. From a distance, it was a scene out of Dickens. Close up was a different story. Still in her teens, she had hennaed her short spiked hair. The eyes behind the circular tinted glasses were themselves round and dark, and she sported three earrings in either ear, with another curling from her left nostril. Rebus didn't doubt she'd have a pale boyfriend with lank dreadlocks and a whippet on a length of clothes-rope.

I'm looking for the manager,' he said.

'He's not here. Can I help?'

Rebus shrugged, his eyes on the cat. It had leapt silently on to the desk and was now rubbing itself against the books. The girl held her pencil out towards it, and the cat brushed the tip with its jaw.

'Inspector Rebus,' said Rebus. I'm interested in some stolen books. I was wondering if anyone had been in trying to sell them.'

'Do you have a list?'

Rebus did. He drew it out of his pocket and handed it over. 'You can keep it,' he said. 'Just in case.'

She glanced down the typed list of titles and editions, her lips pursed.

'I don't think Ronald could afford them, even if he was tempted.'

'Ronald being the manager?'

'That's right. Where were they stolen from?'

'Round the corner in Buccleuch Place.'

'Round the corner? They'd hardly be likely to bring them here then, would they?'

Rebus smiled. 'True,' he said, 'but we have to check.'

'Well, I'll hang on to this anyway,' she said, folding the list. As she pushed it into a desk drawer, Rebus reached out a hand and stroked the cat. Like lightning, a paw flicked up and caught his wrist. He drew back his hand with a sharp intake of breath.

'Oh dear,' said the girl. 'Rasputin's not very good with strangers.'

'So I see.' Rebus studied his wrist. There were inch-long claw marks there, three of them. Whitened scratches, they were already rising, the skin swelling and breaking. Beads of blood appeared. 'Jesus,' he said, sucking on the damaged wrist. He glared at the cat. It glared back, then dropped from the desk and was gone.

'Are you all right?'

'Just about. You should keep that thing on a chain.'

She smiled. 'Do you know anything about that raid last night?'

Rebus blinked, still sucking.' What raid?'

'I heard the police raided a brothel.'

'Oh?'

'I heard they caught an MP, Gregor Jack.'

'Oh?'

She smiled again. 'Word gets about.' Rebus thought, not for the first time, I don't live in a city, I live in a bloody village…

'I just wondered,' the girl was saying, 'if you knew anything about it. I mean, if it's true. I mean, if it is…' she sighed.' Poor Beggar.',

Rebus frowned now.

'That's his nickname,' she explained. 'Beggar. That's what Ronald calls him.'

'Your boss knows Mr Jack then?'

'Oh yes, they were at school together. Beggar owns half of this. She waved a hand around her, as though she were proprietress of some Princes Street department store. She saw that the policeman didn't seem impressed. 'We do a lot of business behind the scenes,' she said defensively. 'A lot of buying and selling. It might not look much, but this place is a goldmine.'

Rebus nodded. 'Actually,' he said, 'now that you mention it, it does look a bit like a mine.' His wrist was crackling now, as though stung by nettles. Bloody cat. 'Right, keep an eye out for those books, won't you?'

She didn't answer. Hurt, he didn't doubt, by the 'mine' jibe. She was opening a book, ready to pencil in a price. Rebus nodded to himself, walked to the door, and rubbed his feet noisily on the mat before leaving the shop. The cat was back in the window, licking its tail.

'Fuck you too, pal,' muttered Rebus. Pets, after all, were his pet hate.

Dr Patience Aitken had pets. Too many pets. Tiny tropical fish… a tame hedgehog in the back garden… two budgies in a cage in the living room… and, yes, a cat. A stray which, to Rebus's relief, still liked to spend much of its time on the prowl. It was a tortoiseshell and it was called Lucky.

It liked Rebus.

'It's funny,' Patience had said, 'how they always seem to go for the people who don't like them, don't want them, or are allergic to them. Don't ask me why.'

As she said this, Lucky was climbing across Rebus's shoulders. He snarled and shrugged it off. It fell to the floor, landing on its feet.

'You've got to have patience, John.'

Yes, she was right. If he did not have patience, he might lose Patience. So he'd been trying. He'd been trying. Which was perhaps why he'd been tricked into trying to stroke Rasputin. Rasputin! Why was it pets always seemed to be called either Lucky, Goldie, Beauty, Flossie, Spot, or else Rasputin, Beelzebub, Fang, Nirvana, Bodhisattva? Blame the breed of owner.

Rebus was in the Rutherford, nursing a half of eight-shilling and watching the full-time scores on TV, when he remembered that he was expected at Brian Holmes' new house this evening, expected for a meal with Holmes and Nell Stapleton. He groaned. Then remembered that his only clean suit was at Patience Aitken's flat. It was a worrying fact. Was he really moving in with Patience? He seemed to be spending an awful lot of time there these days. Well, he liked her, even if she did treat him like yet another pet. And he liked her flat. He even liked the fact that it was underground. Well, not quite underground. In some parts of town, it might once have been described as the 'basement' flat, but in Oxford Terrace, well-appointed Oxford Terrace, Stockbridge's Oxford Terrace, it was a garden flat. And sure enough it had a garden, a narrow isosceles triangle of land. But the flat itself was what interested Rebus. It was like a shelter, like a children's encampment. You could stand in either of the front bedrooms and stare up out of the window to where feet and legs moved along the pavement above you. People seldom looked down. Rebus, whose own flat was on the second floor of a Marchmont tenement, enjoyed this new perspective. While other men his age were moving out of the city and into bungalows, Rebus found a sort of amused thrill from walking downstairs to the front door instead of walking up. More than novelty, it was a reversal, a major shift, and his life felt full of promise as a result.

Patience, too, was full of promise. She was keen for him to move more of his things in, to 'make himself at home'. And she had given him a key. So, beer finished, and car persuaded to make the five-minute trip, he was able to let himself in. His suit, newly cleaned, was lying on the bed in the spare bedroom. So was Lucky. In fact. Lucky was lying on the suit, was rolling on it, plucking at it with his claws, was shedding on it and marking it. Rebus saw Rasputin in his mind's eye as he swiped the cat off the bed. Then he picked up the suit and took it to the bathroom, where he locked the door behind him before running a bath.

The parliamentary constituency of North and South Esk was large but not populous. The population, however, was growing. New housing estates grew in tight clusters on the outskirts of the mining towns and villages. Commuter belt. Yes, the region was changing. New roads, new railway stations even. New kinds of people doing new kinds of jobs. Brian Holmes and Nell Stapleton, however, had chosen to buy an old terraced house in the heart of one of the smallest of the villages, Eskwell. Actually, it was all about Edinburgh in the end. The city was growing, spreading out. It was the city that swallowed villages and spawned new estates. People weren't moving into Edinburgh; the city was moving into them.
