‘No, it’s not really to do with the . . . with Mr Jack’s . . . no, it’s more to do with Mrs Jack.’

‘Lizzie? What about her?’

‘We’re not sure where she is. Any ideas?’

Byars looked blank. ‘Knowing Lizzie, you’d better get Interpol on the case. She’s as likely to be in Istanbul as Inverness.’

‘What makes you say Inverness?’

Byars looked stuck for an answer. ‘It was the first place that came to mind.’ Then he nodded. ‘I see what you mean though. You were thinking she might be at Deer Lodge, it being up that way. Have you looked?’

Rebus nodded. ‘When did you last see Mrs Jack?’

‘A couple of weeks ago. Maybe three weekends ago, I can check. Funnily enough, it was at the lodge. A weekend party. The Pack mostly.’ He looked up from his drink. ‘I better explain that . . .’

‘It’s all right, I know who The Pack are. Three weekends ago, you say?’

‘Aye, but I can check if you like.’

‘A weekend party . . . you mean a party lasting the whole weekend?’

‘Well, just a few friends . . . all very civilized.’ A light came on behind his eyes. ‘Ah-ha, I know what you’re getting at. You know about Liz’s parties then? No, no, this was tame stuff, dinner and a few drinks and a brisk country walk on the Sunday. Not really my mug of gin, but Liz had invited me, so . . .’

‘You prefer her other kinds of party?’

Byars laughed. ‘Of course! You’re only young once, Inspector. I mean, it’s all above board . . . isn’t it?’

He seemed genuinely curious, not without reason. Why should a policeman know about ‘those’ parties? Who could have told him if not Gregor, and what exactly would Gregor have said?

‘As far as I know, sir. So you don’t know any reason why Mrs Jack might want to disappear?’

‘I can think of a few.’ Byars had finished both drinks, but didn’t look like he was hanging around for another. He kept shifting on the stool, as if unable to get comfortable. ‘That newspaper story for a start. I think I’d want to be well away from it, wouldn’t you? I mean, I can see how it’s bad for Gregor’s image, not having his wife beside him, but at the same time . . .’

‘Any other reasons?’

Byars was half standing now. ‘A lover,’ he suggested. ‘Maybe he’s whisked her off to Tenerife for a bit of pash under the sun.’ He winked again, then his face became serious, as though he’d just remembered something. ‘There were those phone calls,’ he said.

‘Phone calls?’

Now he was standing. ‘Anonymous phone calls. Lizzie told me about them. Not to her, to Gregor. Bound to happen, the game he’s in. Caller would phone up and say he was Sir Somebody-Somebody or Lord This ’n’ That, and Gregor would be fetched to the phone. Soon as he got to it, the line would go dead. That’s what she told me.’
