‘As I say, Mr Kilpatrick, I don’t think anything. All I know is that a murder inquiry is under way, Mrs Jack’s last known whereabouts remain this lodge, and now someone’s trying to tamper with evidence.’ Rebus paused. ‘That’s all I know. You can come inside now, but, please, don’t touch anything. I’d like to ask you all a few questions.’

Really, what he wanted to ask was: Is the house pretty much in the state you remember it from the last party here? But he was asking too much. Yes, they remembered drinking champagne and armagnac and a lot of wine. They remembered cooking popcorn in the microwave. Some people drove off – recklessly, no doubt – into the night, while others slept where they lay or staggered off into the various bedrooms. No, Gregor hadn’t been present. He didn’t enjoy parties. Not his wife’s, at any rate.

‘A bit of a bore, old Gregor,’ commented Jamie Kilpatrick. ‘At least, I thought he was till I saw that story about the brothel. Just goes to show . . .’

But there had been another party, hadn’t there? A more recent party. Barney Byars had told Rebus about it that night in the pub. A party of Gregor’s friends, of The Pack. Who else knew Rebus was on his way up here? Who else knew what he might find? Who else might want to stop him finding anything? Well, Gregor Jack knew. And what he knew, The Pack might know, too. Maybe not one of these three then; maybe someone entirely different.

‘Seems funny,’ said Louise Patterson-Scott, ‘to think we won’t be having parties here any more . . . to think Liz won’t be here . . . to think she’s gone . . .’ She began to cry, loudly and tearfully. Jamie Kilpatrick put an arm around her, and she buried her face in his chest. She reached out a hand and found Julian Kaymer, pulling him to her so that he, too, could be embraced.

And that’s pretty much how they were when Constable Moffat arrived . . .

Rebus, with a real sense of bolting the stable door, left Moffat to stand guard, much against the young man’s will. But the forensics team would be arriving before lunchtime, and Detective Sergeant Knox with them.

‘There are some magazines in the bathroom, if you need something to read,’ Rebus told Moffat. ‘Or, better still, here . . .’ And he opened the car, reached into his bag, and took out Fish out of Water. ‘Don’t bother returning it. Think of it as a sort of present.’

Then, the Daimler having already left, Rebus got into his own car, waved back at Constable Moffat, and was off. He’d read Fish out of Water last night, every fraught sentence of it. It was a dreadful romantic tale of doomed love between a young Italian sculptor and a wealthy but bored married woman. The sculptor had come to England to work on a commission for the woman’s husband. At first, she uses him like a plaything, but then falls in love. Meantime, the sculptor, bowled over by her at first, has moved his attentions to her niece. And so on.
