Prabir took comfort in the usual routine: wading to the beach, insect repellent, mine detector checks. Looking back at the reef as he pulled on his boots. They’d gather some samples and return to the boat. It would be a day like any other.

He’d estimated GPS coordinates for the kampung, from his notepad’s log of its position the previous day and his recollection of the treetop view. They picked their way laboriously through the shrubs; this was the first time they’d had no choice about their destination, no option of taking an easier route. Grant had once tried clearing a path in the undergrowth using a parang she’d bought in Ambon, but it had been a waste of effort; the machete was perfect for chopping through occasional vines, but the knee-high thicket was too tangled, there were too many strands to sever.

Grant was unusually quiet; she might have done this easily enough alone, but his presence must be making her feel more like a trespasser. Prabir said, ‘You wouldn’t believe it only took me half an hour a day to maintain this path.’

‘That was one of your jobs?’

‘Yeah.’

She smiled. ‘I thought I was hard done by having to clean the bath. And at least I had somewhere to spend my pocket money. I suppose you got paid in net privileges?’

‘I don’t remember.’

Prabir’s eyes kept filling with sweat. As he wiped them clear, he could almost see the approach as it had once been. He’d heard the thud of the mine and raced towards the kampung with Madhusree in his arms. Sailing past the trees ever faster, as if he was falling.

Grant spotted one of the huts before he did: it was leaning precariously, covered in fungus and lianas. Unlike the roofing panels he’d seen from above, the walls were stained and encrusted to the point where they might as well have been deliberately camouflaged. Prabir was suddenly much less sure that they’d followed the old path; he didn’t expect the hut to be recognisable, but its position was not where he’d imagined it. Maybe they’d taken a different route entirely, one that had always been uncleared jungle.

Even when they were standing at the edge of the kampung, it took him a while to find all six huts amid the trees. He said numbly, ‘I don’t know where we are. I don’t know where to start.’

Grant put a hand on his shoulder. ‘There’s no rush. I can look inside one of these buildings and describe it for you, if you like.’

‘No. It’s all right.’ He turned and walked towards the hut on his right. The doorway facing the centre of the kampung was hidden beneath a dense mat of creepers, but the walls had split apart at one corner, leaving a gap that made a much easier entrance.

Grant came after him. ‘You need a torch, and we need to do this slowly. We don’t know what’s in there.’

Prabir accepted the flashlight from her. She unslung her rifle and followed behind him as he ducked down to enter the hut. Enough soil had blown in, and enough sunlight came through the gap in the walls and the vine-draped windows to cover the floor in pale weeds. There was a hook on one wall, and the cracked, shrivelled remnants of a rectangle of canvas curled up beneath it.

He said, ‘This was mine.’ He gestured at the hammock. ‘That was where I slept.’

‘Right.’

Termites must have devoured the packing crate where he’d kept his clothes, once the preservative had leached out of the wood. The hut looked barer than a prison cell now, but it had never been full of gadgets and ornamentation; all the possessions he’d valued most had been stored in his notepad.

He’d looked out at night from this hut, his stomach cramped with anxiety. And then he’d thought of an act that would justify everything he was feeling: a crime to match his sense of guilt, an alibi to explain it.

Guilt about what, though? Had he stolen something, broken something? What could be worse than sabotaging his parents’ work?

‘The butterfly hut.’ He backed out, then tried to orient himself. ‘It was straight across the kampung.’

He threaded his way between the trees, with Grant walking beside him in silence. It was the most direct route, but he lost sight of the surrounding huts, lost count of their position in the circle.

The door had fallen off the hut he approached, leaving an entrance curtained with creepers. Grant handed him the parang and he slashed them away. Then he pointed the flashlight into the darkness.

Madhusree’s plastic cot was covered in fungus, warped and discoloured but still intact. Behind it, his parents’ folding bunk was strewn with debris, the foam mattress rotted, the metal frame a shell of corrosion.

He’d been afraid for them. Afraid the war would reach them, in spite of the island’s obscurity, in spite of his father’s reassurances.

But why would he feel guilty? Why would he imagine that he’d be to blame if the war came to the island? Even if he’d fought with his parents and wanted them punished—even if he’d shouted from the slopes of the volcano that he’d wanted them dead—he’d never been superstitious enough to believe that his wishes would be granted.

Prabir said, ‘Wrong hut. It’s the next one.’

One wall of the butterfly hut had collapsed outwards, leaving the two half-supported roofing panels to swing down almost to the ground. The result was a rickety triangular prism, with a narrow space between one standing wall and the tilted roof through which Prabir could just squeeze. Grant followed him.

The wall that had fallen had borne the hut’s windows and door, and the soft forest light hit the gaps in the structure at the wrong angle to penetrate the darkness ahead. Prabir played the flashlight beam along the floor, looking for signs of the lab bench, but the wood had all gone to termites and fungus. The hut was knee deep in twigs and rotting leaves, debris that had blown in and never found its way out again.

In the far corner, two yellow eyes caught the beam. There was a python, maybe half the size of the one in the mangroves, coiled on top of a pile of litter. Prabir felt his legs turn to water at the sight of it, but he didn’t want it killed unnecessarily.

‘Maybe we can work around it,’ he suggested. ‘Or drive it out with sticks.’

Grant shook her head. ‘Normally I’d agree, but right now we can do without the aggravation.’ She raised her rifle. ‘Stand aside and cover your ears.’ She dropped a pinprick of laser light between the snake’s eyes, then blew its head off. Clumps of white fungus rained from the ceiling. The snake’s decapitated body twitched and rose into a striking position, uncoiling enough to reveal a clutch of fist-sized blue-white eggs.

Grant held the flashlight while Prabir sifted through the mess on the floor. It was slow work, and the humid air above the decaying leaves was suffocating. When he found the metal stage of his father’s microscope he gave up all pretence of being in control and let tears of grief and shame run down his face.

He knew what he’d done. He knew why he’d poisoned the chrysalis, he knew what he’d needed to hide.

He’d killed them. He’d brought the plane to the island, he’d brought the mines.

It was too much to face. He couldn’t live, staring into that light—but he’d lost all power to avert his gaze, and every lie he’d held up as a shield was transparent now. He had to let it melt him, he had to let it burn him away.

He was determined to find the specimens first; they were the last things left that he could hope to salvage. Grant stopped asking him if he wanted to rest or swap positions. Beetles and pale spiders fled as he plunged his hands into the leaves, again and again.

He pulled out a slab of light, cool plastic, thirty centimetres wide, covered in filth. He wiped it on his jeans. It was an adult butterfly, embedded in something like lucite. An adult from twenty years ago, with the old concentric green-and-black stripes.
