And Prabir had pictured the green-and-black insects by the millions, carpeting the ground in place of grass, nesting in the trees in place of leaves.

A month after the coup, Prabir received a message from Eleanor. He closed the door to his hut and lay on his hammock with his notepad beside him, turning down the volume until he was certain that no one outside could hear. The message was video, as usual, but this time Eleanor hadn’t roamed the city with the camera, or even prowled her own apartment cornering her irritated teenage children. She simply sat in her office and spoke. Prabir felt guilty that he’d never been able to repay her in kind for the tours of New York, but if he’d owned up to having a suitable camera at his disposal it would have been impossible to justify the pure text messages that concealed his true age.

Eleanor said, ‘Prabir, I’m worried about you. I understand that you don’t want to interrupt your work—and I know how difficult and expensive it would be to charter a boat now—but I still hope you’ll reconsider. Will you hear me out?

‘I’ve been looking at the latest State Department report on the crisis.’ A URL came through on the data track, and the software automatically attempted to open it, but the ground station in Sumatra through which Prabir was connected to the wider world was blocking the site. ‘Kopasus troops are being flown in to Ambon; I’m sure you know the kind of things they’ve been doing in Aceh and Irian Jaya. And you’re in a typical hiding place for an ABRMS base; I know you’re there with official permission, but if you’re relying on bureaucrats in Jakarta to dig up the relevant file and instruct the army to stay out of your way… I think that might be a bit too optimistic.’

Eleanor hunched towards the camera unhappily. ‘This isn’t going to blow over in a month or two; even if the President is restored to office, there’s almost nothing the government could do now to put things right. For the past sixty years, people in the provinces have tolerated rule from Jakarta so long as there was some token respect for the customary power structures, and some token spending on things like health and education in return for all the timber, fishing and mineral rights being handed over to the cartels. But after fifteen years of austerity programmes—with every spare rupiah going to subsidise the cost of living in the major cities, to stave off riots—the imbalance has become impossible to ignore. Forget religious and ethnic differences; the provinces have been bled dry, and they’re not going to put up with it any longer.’

There was more in the same vein. Prabir listened to it all with a mixture of unease and annoyance. His parents had decided that the safest thing to do was stay put, attract no attention, and ride out the storm. Teranesia had no strategic importance, so neither side had reason to come here. Who was Eleanor to think she knew better, from twenty thousand kilometres away?

Still, it was clear that she was genuinely worried about him, and Prabir didn’t like to see her upset. He’d send back a confident, up-beat reply that would put her mind at ease… without casting doubt on her conclusions, or questioning her expertise.

Prabir pressed one foot against the wall of the hut and rocked the hammock gently while he composed his reply. He began by mentioning the garden, and how well it was doing, though in truth it was full of starchy native tubers that would probably taste like cardboard. ‘Rajendra is weeding it diligently every day. He’s such a good boy!’ He dictated the words to the notepad and it converted them into text; he’d almost patched the software to add random typing errors, but then he’d decided that even the oldest, cheapest keyboard-driven notepad would have corrected them as they were made.

He added a few vaguely positive words about ‘my work’, but there was nothing new to report. His parents had gathered a wealth of data as they observed generation after generation of the butterfly in the setting that had, presumably, shaped its strange adaptations, but as far as Prabir could tell they were still no closer to an explanation. Nothing about Teranesia was wildly different from other islands in the region, and even eighty kilometres of water—and much less during ice ages—was no real barrier to migration on a time scale of tens of millions of years.

He left any mention of politics to the end, and ran through the words in his head a dozen times before committing a first draft to the notepad. He had to sound like his father, but firmer and clearer, so Eleanor wouldn’t keep questioning his decision to stay. Instead of dismissing her fears that the worst might happen, he’d welcome the possibility with open arms.

‘By the way, I checked out that State Department report you mentioned, and I agree completely with your analysis of the situation. The brutal, corrupt Javanese empire is finally coming to an end! Like the Portuguese, and the Dutch, and the British, they’re going to have to learn to live within their own borders. And if they can’t read the lessons of history, ABRMS is going to have to teach them the hard way.

‘But please don’t worry about me and my family. The army will never even think of coming here. We have all the equipment and supplies we need, so we can stay holed up here for as long as we have to. And it’s not as if Radha and I have nothing to do! We’ll continue with our work, until it’s safe to leave.’

Safe to leave?That wouldn’t inspire much confidence. He slid the cursor back across the screen with his finger. ‘… until victory is accomplished!’

Prabir hesitated. It still sounded a bit like whistling in the dark. He needed to sign off on a positive note, or Eleanor would think it was all bluster.

He closed his eyes and swung the hammock, sighing with frustration.

Then inspiration struck.

‘As ever, your friend Prabir. Long live the Republik Maluku Selatan!’

‘Be careful!’ Prabir’s mother shaded her eyes and looked up at him, shifting Madhusree to one side to free her arm. Prabir stepped off the ladder on to the gently sloping roof. There were no gutters, so there was nothing to stop him falling if he started to slide, but the surface of the photovoltaic composite felt reassuringly rough beneath his feet. The modified fibreglass gained efficiency from its lack of polish; the polymer strands could gather more light if they stuck out in random tufts.

Prabir crouched down slowly, legs spaced, balancing carefully. He’d managed to convince his parents that they were both too heavy to walk on the roofs of the huts, and though he’d been arguing entirely for the sake of doing the job himself, it seemed he’d been right: he could feel the panels flexing beneath his feet. They still felt springy, but it probably wouldn’t have taken much more force to buckle them.

He shook the spraycan and began to paint an ‘I’. His parents had argued it through the night before: no elaborate messages proclaiming neutrality, no Indian flag, no sycophantic declarations of loyalty to either side, no praise-be to Allah or Jesus. Just one word on every wall and every roof of every hut: ILMUWAN. Scientist.

The hope remained that no sign was needed. No one had troubled them so far, and since it seemed unlikely that their presence had gone unnoticed, perhaps their purpose was already known. Jets had flown over the island a few times, tiny soundless metallic specks, so small that Prabir could almost believe that they were just flaws in his vision, like the swimming points of distortion he saw when he stared too long into a cloudless sky. Whether they were scanning the island for rebel bases, or merely passing over on their way elsewhere, it was hard to feel threatened when all you could see was a glint of sunlight.

The whole Emergency was becoming like that: distant, hallucinatory, impossible to resolve in any detail. Their access to the net had been cut off since the beginning of February; presumably Jakarta had pulled the plug on the entire province. They could still get BBC shortwave, but the reception was very patchy, and there was only so much you could cram into an hour-long bulletin that covered all of East Asia. It was clear that the regional independence movements were taking advantage of each other’s actions: the separatists in Aceh were now fighting government troops for control of the district capital, and in Irian Jaya the OPM had bombed an army base in Jayapura—an unexpected move from a group whose weapons were usually described as ‘neolithic’. But while dramatic events like that made it into the bulletins, the day-to-day situation in Tual or Ambon never rated a mention. A web site in the Netherlands had been offering individual reports for every inhabited island group in the Moluccas, and its operators had successfully evaded the Indonesian censors with some fancy rerouteing tricks, right up to the moment of the uniform black-out. Prabir’s father had warned him that the site was probably run by expatriate ABRMS members, but Prabir didn’t care. He wasn’t interested in the voice of neutrality. He wanted a flood of propaganda washing over the islands, proclaiming bloodless victory to the rebels. He wanted everyone in Indonesia to talk themselves into believing that they could walk unharmed out of the ashes of the burning empire.
