‘Sure.’ Not exactly welcoming, but that was because of the mood he was in, not because he resented Dougie asking. Ben gave Dougie a pile of bird bags and they went out to the Land Rover. Just driving away from the North Light, they had to pull in to the side of the road to let Perez past. He was in Big James’s car and there was a strange woman in the passenger seat.

‘What was all that about at lunchtime?’ Dougie asked.

‘Nothing. Hugh’s really starting to piss me off. That’s all.’

Fine, Dougie thought. Bugger you then if you don’t want to talk. He’d always thought the tabloid papers were right when they said prisoners had it easy. A warm cell with a telly and someone to bring you food. What punishment was there in that? Now he thought the hard bit would be keeping sane, surrounded by all those strangers. No privacy. No wonder living in the centre had driven Angela crazy. Dougie had only been stuck here for a few weeks and he was already going mad.

They parked by the double dyke and did the rest of the trap round on foot.

In the gully trap, Dougie walked through the vegetation, pishing and knocking against the stunted sycamores, to push any birds resting there towards the catching box. There was always a chance of something unusual, but today they only caught two meadow pipits that had already been ringed two days earlier. Ben held them for Dougie to see, then let them go.

‘Would it have hurt some eternal plan if one had been an olive-backed?’ Dougie said. ‘I mean, I know we’ve all seen olive-backed before, but it would have been something, wouldn’t it? Something to cheer everyone up.’

They scrambled back on to the road and moved on to the plantation trap. When Dougie had first come to Fair Isle the plantation had been a joke, the name ironic. A few straggly pines planted in a fold in the land, with the trap built over them. Now the trees had grown up, some of them through the wire mesh. Inside it smelled and felt like a real wood. There were pine needles on the floor. Dougie walked through it rustling the lower branches, felt the same expectation, hope and excitement as he always did. The plantation was where he’d seen the brown flycatcher. There was a small bird somewhere ahead of him. He heard it fluttering, just caught a glimpse of movement. Then he tripped on a root that had grown out of the thin soil, fell hard and couldn’t stop his cheek from hitting the ground. There’d be a cracking bruise later. He swore under his breath. On the other side of the wood, Ben yelled to ask if he was OK.
