‘Left and then right . . . along the track beside a fir plantation . . . up to the top of the rise . . . through a gateway. It’s like Treasure Hunt.’ The car was behaving impeccably (touch wood). Touch wood? He only had to stop the car and stretch his arm out of the window. No plantation now, but a wild wood. The track was heavily rutted, with grass growing high along a strip between the ruts. Some of the larger potholes had been filled in with gravel, and Rebus’s speed was down to five miles an hour or less, but that didn’t seem to stop his bones being shaken, his head snapped from side to side. It didn’t seem possible that there could be a habitation ahead. Maybe he’d taken a wrong turning. But the tyre tracks he was following were fresh enough, and besides, he didn’t fancy reversing all the way back along the trail, and there was no spot wide enough for a three-point turn.

At last, the surface improved, and he was driving on gravel. As he turned a long, high-cambered bend, he found himself suddenly in front of a house. On the grass outside was parked a police Mini Metro. A narrow stream trickled past the front entrance. There was no garden to speak of, just meadow and then forest, and a smell of wet pine in the air. In the distance, beyond the back of the house, the land climbed and climbed. Rebus got out of the car, feeling his nerves jangle back into position. The door of the Metro had already opened, and out stepped a farm labourer in police uniform.

It was like some sort of Guinness challenge: how large a man can you get in the front of a Mini Metro? He was also young, late teens or early twenties. He gave a big rubicund smile.

‘Inspector Rebus? Constable Moffat.’ The hand Rebus shook was as large as a coal shovel but surprisingly smooth, almost delicate. ‘Detective Sergeant Knox was going to be here, but something came up. He sends his apologies and hopes I’ll do instead, this being my neck of the woods, so to speak.’

Rebus, who was rubbing his neck at this point, smiled at the joke. Then he pressed a thumb either side of his spine and straightened up, exhaling noisily. Vertebrae clicked and crunched.

‘Long drive, eh?’ Constable Moffat commented. ‘But you’ve made not bad time. I’ve only been here five minutes myself.’

‘Have you had another look round?’

‘Not yet, no. Thought I’d best wait.’

Rebus nodded. ‘Let’s start with the outside. Big place, isn’t it? I mean, after that road up to it I was expecting something a bit more basic.’

‘Well, the house was here first, that’s the point. Used to have a fine garden, well-kept drive, and that forest was hardly there at all. Before my time, of course. I think the place was built in the 1920s. Part of the Kelman estate. The estate got sold off bit by bit. There used to be estate workers to keep the place in check. Not these days, and this is what happens.’
