Brian kept quiet, as though he didn’t even care whether he got a present. All that interested him was pop music, and Banks had bought him a second-hand guitar he’d spotted in a shop window. Of course, it would mean a bit of noise to put up with. Banks didn’t have much regard for his son’s taste, but far be it from him to stand in the way of the lad’s musical ambitions. Euterpe, like God, works in mysterious ways; raucous pop music might inspire someone to learn the guitar, but tastes change, and the talent might well end up in the service of jazz, blues or classical music.

Tracy had been a good deal less specific in her demands, but both Banks and Sandra had thought it a good idea to acknowledge that she was no longer a little girl. She was, after all, fifteen, and though her interest in history remained steady, and had even extended to take in literature, she had a new look in her eyes when the subject of boys came up. Banks had also noticed the odd pop star poster surreptitiously making its way onto her bedroom wall. So rather than books, they had bought her some fashionable new clothes and a make-up kit. When Banks looked at his children now, it was with a tinge of sadness in his heart. Next year he would be forty, and soon he would lose them to their own lives completely.

After a tasty beef stew with dumplings – a frugal dinner to counterbalance tomorrow’s blow-out – came that time of evening when Banks could start to relax: the children out or occupied in their rooms, the television turned off, a tumbler of good Scotch, quiet music and Sandra beside him on the sofa. When he went for his refill, he remembered the photograph he had brought home in his briefcase along with the record Vic Manson had sent over that afternoon. He had hardly looked at it, but something about it rang a bell. Sandra, with her knowledge of photography, should be able to help him. He took the photograph out and handed it to her.

‘What do you think of that?’

Sandra examined it close up, then held it at arm’s length. ‘Do you mean technically?’

‘Any way you like.’

‘Well, it’s obviously good, a professional job. You can tell that by the lighting and the way he’s made it seem like a relaxed pose. She looks very studious. A striking woman. Good quality paper, too.’

‘Why would someone have a photograph like that taken?’

‘Well, lots of people have portraits done… but I see what you mean.’

‘There’s something about it I can’t put my finger on,’ Banks said. ‘Somehow, I think it’s more than a portrait. I just wondered if you had any ideas.’

‘Hmm. That look in her eyes. Very intelligent, a bit haughty. I wonder if that was her or the photographer.’

‘What do you mean?’

‘Some photographers really capture a person’s essence in their portraits, but some create an image – you know, for pop stars or advertising. I’m just not sure what this is.

‘That’s it!’ Banks slapped the chair arm. ‘An image. A pose. Why would someone want a photographer to create an image?’

Sandra put the photograph carefully aside on the coffee table. ‘For publicity, I suppose.’

‘Right. That’s what was bothering me. It must be a publicity picture of some kind. That gives us a chance of tracking her down.’

‘You need to find this woman?’

‘Yes.’

‘You’ll still have a hell of a job. It could be for anything – modelling, movies, theatre.’

Banks shook his head. ‘Caroline had an interest in theatre, but I get the impression that’s more of a recent passion. Still, she could be an actress. She’s attractive, yes, but she’s no model. You said it yourself – look at the intelligence, the arrogance in that tilt of the head and the eyes. And Veronica Shildon said the woman wrote poetry.’

‘A book jacket?’

‘Those are the lines I was thinking along. It could be a publicity still for an author’s tour or something. That should narrow things down a bit. We can check with publishers and theatrical agents.’ Banks paused for a moment, then went on. ‘Speaking of Caroline Hartley, did you ever meet her?’

‘I met her a couple of times with the group, when I went for a drink with Marcia after working late in the gallery. But I didn’t know her. I never even spoke to her.’

‘What was your impression?’

‘I can only tell you how she acted as part of a group in a pub. She was very beautiful. You couldn’t help but notice her smooth complexion and her eyes. Notice and envy.’ Sandra put her hand to her own cheek which Banks had always thought of as soft and unblemished. ‘In looks, she reminded me a bit of that actress who played Juliet in the old film. What’s her name?… Olivia Hussey. And mostly she was vivacious, sparkling. Though she did seem to have her quiet periods, as if the energy was a bit of a hard act to keep up sometimes.’

‘Quiet periods?’

‘Yes. I just remember her staring into space sometimes, looking a bit lost. Never for long, because there was always somebody wanting to attract her attention, but it was noticeable.’

‘Did she seem especially close to anyone else in the group?’

‘I don’t know. She chatted and laughed with them all, but only in a general, friendly way.’

‘You never saw her arguing with anyone?’

‘No.’

‘Did you know she was a lesbian?’

‘Not until you told me. But why would I?’

‘I don’t know. I just wondered if it was in any way obvious to you.’

‘No – to both questions.’

‘Did you ever notice anyone obviously chatting her up?’

Sandra laughed. ‘Well, most of the men did, yes.’

‘How did she react?’

‘I’d say she played them along nicely. If anything, I’d have said she was a flirt, a bit of a tease, really. But now I know the truth…’

‘Self-protection, I suppose. What about the women?’

Sandra shook her head. ‘I didn’t notice anything.’

‘Did James Conran usually turn up for a drink? He’s the only one I’ve met apart from Marcia, the costume manager.’

‘Usually, yes. He seems like a pleasant fellow. A bit theatrical, highly strung. Drinks a fair bit. I mean, a lot of actors are really shy, aren’t they? They have to get themselves tanked up and play parts to express themselves And he’s a bit of a practical joker. Nothing serious, he just likes arranging for someone’s drink to be all tonic and no gin, for example, or having the barman tell someone there’s none of their favourite pub grub left. I’d say he’s a bit of a ladies’ man, too. You know, that vulnerable look, the dedicated, suffering artist. He’s pretty sure of himself really, I’ll bet. He just finds the act useful. And I know for a fact he’s been having it off with Olivia.’

‘Olivia who?’

‘I don’t know her real name. The actress who’s playing Olivia. They had a bit of a tiff in the pub one night, in the corridor that leads to the toilets, and I happened to overhear them arguing. She seemed to think now he’d got what he wanted he wasn’t interested any more, and she told him that was fine with her, because she hadn’t liked it much anyway.’

‘When was this?’

‘Quite early on in rehearsals. I can’t remember exactly. Mid-November, maybe?’

‘Did he ever make a pass at you?’

‘No. He knew I was married to a tough detective who’d beat him to a pulp if he did.’

Banks laughed. ‘What about Caroline?’

‘You mean did he come on to her?’

‘Yes.’

‘Well, he contrived to sit next to her often enough and arrange for the occasional bit of accidental body contact. I’d say he was putting the moves on her, yes.’

No wonder Conran had been so tetchy when Banks had asked about his relationship with Caroline. People often denied their true relationships with victims, especially with murder victims.

‘How did she react?’ he asked.

‘She pretended she didn’t notice, but she was always polite and friendly towards him. After all, he is the director.’

‘I should hardly think directors of local amateur dramatic societies have casting couches.’
