Richmond raised his eyebrows at the mention of Burgess. Banks and Dirty Dick had locked horns over a politically sensitive case in Eastvale last spring, and they had hardly parted on the best of terms. Apart from Banks and Burgess, only Richmond knew the full story.

Banks looked at his watch and finished his pint. ‘Right. I’d better be off now. I want to see if that post-mortem report’s turned up yet.’ It was already dark outside and the snow had just started falling again.

The report had indeed turned up. Banks skipped the technical details for the layman’s synopsis that Dr Glendenning always courteously provided.

There was nothing new at first. She had been hit, probably punched, on the cheek, and the blow could have rendered her unconscious. After that, she had been viciously and repeatedly stabbed with her own kitchen knife. The only blood found at the scene was hers. Her dressing gown had no bloodstains on it, so it had been removed – or Caroline herself had removed it – before the stabbing. Glendenning had found no signs at all of sexual interference. He had, however, found crumbs of chocolate cake in several of the wounds, which led him to believe that the knife had been lying by the cake on the table. If so, Banks thought, they were probably dealing with a spur of the moment attack, a weapon at hand, grabbed and used in anger. There were no signs of skin or blood under her fingernails, which meant she hadn’t had a chance to fight off her attacker.

And that was it, apart from the general information Banks read idly through – health basically sound, appendix scar, gave birth to a child… He stopped and read that part over again. According to Glendenning, who had been as thorough as usual, the cervix showed a multiparous os, which meant the deceased had, at some point, had a baby.

That cast an interesting new light on things. Not only did it mean she had had at least one heterosexual relationship, it might also explain why she went to London, or what might have happened to her down there. All the more imperative, therefore, to find out exactly where she’d been and what she’d done. Banks felt that the photograph was a clue. Given that it was the only memento she’d kept, apart from a pressed flower, Ruth was obviously someone important from Caroline’s past.

Banks walked over to the window and looked out on the market square. It looked like one of Brueghel’s winter scenes. The tree was lit up and shoppers crossed the whitened cobbles to and fro with their packages. Banks was glad he’d done his Christmas shopping a week ago. The only thing that remained was the booze. He’d buy that tomorrow: a bottle of port, a nice dry sherry, perhaps some Ciardhu single malt, if he could afford it. Then his thoughts drifted back to Caroline Hartley. A baby. What a bloody turn up! And if there was a baby, somewhere there had to be a father. Maybe a father with a grudge.

Eager to find out if there had been any progress on the record and the scrap of wrapping paper, he phoned the forensic lab and asked for Vic Manson.

Manson was slightly breathless when he came on the line. ‘What is it? I’d just this minute put my overcoat on. I was on my way out.’

Banks smiled to himself and lit a cigarette. Manson was always on his way somewhere. ‘Sorry, Vic. I won’t keep you long. Just wanted to know if you’ve got anything for us on the Hartley murder.’

Manson sighed. ‘Not a lot. No dabs we can’t account for. The knife was washed, but we found traces of blood and crumbs where the blade meets the handle.’

‘What about the record?’

‘Nothing. Besides, people usually hold records by the edge. No room for prints there. The cover and inside sleeve were clean, too.’

‘Anything else?’

‘It looked new, the record. As far as we can tell it was in mint condition, only been played a few times.’

‘How many?’

‘Can’t tell for sure – two or three at the most – but take our word, it was new.’

‘The paper?’

‘Common or garden Christmas wrapping paper. Could have come from anywhere. It does look like it had been wrapped around the record, though. It fits to a tee. But there’s no gift tag with the murderer’s name on, unfortunately.’

‘Well, at least we’ve got something. Thanks, Vic. Look, can you send the record over to me when you’ve done with it?’

‘Of course. Tomorrow okay?’

‘Fine. Don’t let me keep you any longer. And have a good Christmas.’

‘You too.’

Banks hung up, walked back to the window and lit a cigarette. What the hell was it about the music that bothered him? Why did it have to mean something? He would find out as much as he could about Vivaldi’s Laudate pueri, all four versions. Claude Ivers admitted he knew them, but that didn’t mean anything. He must have known that if he’d feigned ignorance, given his musical reputation, Banks would have immediately become even more suspicious. But Ivers knew more than he let on, that was for certain. And so did Patsy Janowski, she of the wandering eyes. Well, give them time, he thought, as he smoked and looked down on the Brueghel scene, they’re not going anywhere. Let them think they’re safe, then…

.James Conran lived in a small terrace house on the northwest edge of town, where Cardigan Drive met North Market Street and turned into the main Swainsdale road. At the far end of his living room, a manual typewriter sat on a table by the window. The view to the west along snow-shrouded Swainsdale was superb. Bookcases flanked the table on both sides with books on all subjects. Banks took a quick glance: history, theatre, music, but hardly any fiction. A small sofa and two matching armchairs formed a semicircle around the hearth, where a coal fire smouldered. On the wall above the mantelpiece hung a poster advertising a performance of The Duchess of Malfi at Stratford. There was no television set, but a music centre with a compact-disc player stood opposite the fireplace. Banks ran his eyes over the records and discs, most of them the works of classical composers: Beethoven, Zelenka, Bax, Stanford, Mozart, Elgar. There was some Vivaldi, including the Stabat Mater, but not the Laudate pueri.

Conran, having explained to Banks how Susan had once been one of his pupils, was now fussing over her and offering to make tea. Both she and Banks accepted.

‘Nice collection of discs,’ Banks observed. ‘Are you a musician?’

‘Merely a dabbler,’ Conran said. ‘I sang with the church choir when I was a boy, then with an amateur outfit in York. I also directed the choir at Eastvale Comprehensive for a few years – mostly, I might add, because no one else would take on the job. But that’s just about the limit of my musical abilities. I am a good listener, however.’

As Conran made tea in the kitchen, Banks continued reading book and record titles. It helped get a sense of people, he always thought, to discover their tastes in literature and music. Conran definitely read to learn, not for pleasure, which hinted at a certain amount of intellectual and artistic ambition. His record collection, while fairly eclectic, favoured choral works, perhaps an unconscious left-over from his choir days. The fact that he owned a compact-disc player showed he was serious about his listening. Though she said she liked classical music, Veronica Shildon only had an old stereo system, a turntable complete with arm and spindle for stacking records. No one who genuinely loved music would play it on such antiquated equipment, especially if they could afford better. No, Veronica Shildon’s priorities lay elsewhere than music – in decor, perhaps, in creating the sense of a cosy and comfortable home. But Conran clearly valued his artistic pleasures over material ones.
