on not spilling her plate of ginger snaps and frothy mug of hot chocolate. She set them down on the walnut desk, touched her shoulder sympathetically. Rebecca took the mug in both hands, savouring the sharp comfort of its heat, staring blankly down at the film of dark skin that thickened and wrinkled upon its cooling surface. Out in the main office, she could hear her staff working their phones, checking visa requirements, moving meetings, cancelling appearances, swept up by the drama of someone else’s tragedy. Ken shouted out that the first flight left Heathrow later that afternoon, flying to Antananarivo via Paris, only business class available. Three thousand five hundred and twenty-eight quid. Should he take it? If so, how should he pay? There was a beat of silence in the office. Rebecca’s breath caught in her throat. She took one hand off her hot chocolate and clenched it beneath the table, only too well aware that her own credit cards would never take such a hit.
‘Company account,’ said Titch.
‘But I thought we weren’t allowed to—’
‘Company account,’ repeated Titch, more firmly. ‘We’ll sort it out later.’
Nicola began reading out a list of prevalent diseases, Lindsay checking them against Rebecca’s vaccination record. Bilharzia, meningitis, rabies, intestinal worms, dengue haemorrhagic fever. Rebecca felt dismay as the list went on. Cholera, filariasis, TB, yellow fever, typhus, hepatitis. She’d lived in Madagascar eighteen years, remembered none of this. A high-risk malignant malarial region with chloroquine and fansidar resistance. Lariam gave her nightmares, doxycycline turned her skin orange; she’d need Malarone instead. They’d a month’s worth in the storeroom. Titch brought in a box, along with a thick sheaf of euros that he slipped clandestinely into her bag. Then he sank to his haunches and spoke slowly and clearly. Everything was in hand. A taxi was on its way to take her home to pack and then on to the airport. Her ticket to Antananarivo was bought and paid for, as was her ongoing flight from Antananarivo to Tulear, the airport nearest her home. They were still working on a driver to meet her at Tulear Airport with a hire car; he’d text her the details the moment he had them. In the meantime, she was to forget about their earlier conversation; he’d handle everything until she got back. She took and squeezed his hand in gratitude. Their eyes met; he seemed on the verge of saying something else, but then thought better of it. The buzzer sounded. Her taxi was already downstairs. She packed up her laptop, her international power adapter and spare fuse, was hurrying to the door when she glanced back, saw her staff gathered in a rough semicircle, their faces solemn and troubled, like mourners at a graveside, as though they’d already accepted the worst.
She stopped and took a pace back towards them. ‘They’re not dead,’ she said defiantly. ‘You hear me? They’re not dead.’
Titch came over and took her in his arms, squeezed her so tight that she could feel their hearts banging. ‘They’re not dead,’ he murmured. ‘You’ll find them. If anyone can, you can.’

Knox arrived in the conference room for Holm’s presentation to find only Miles already there, his feet up on the conference table, scrunching up sheets of paper from his pad, trying to score three-pointers in the waste-paper basket, and not doing very well to judge from the mess he’d made of the floor. ‘Just us?’ he asked.
‘That’s how Ricky wants it,’ said Miles. ‘We’ll brief the others later.’
Knox nodded. The conservators had their hands full with the anchor; the crew with fixing the thrusters and checking hull damage from the anchor. And their MGS colleagues, while expert divers, were mostly veterans of the armed forces or the oil industry, with limited interest in the science or archaeology of the site. Besides, half of them were still on the afternoon dive, and would need to be briefed this evening anyway.
He took a chair, but found it difficult to keep still, so was soon up again, pacing the room. Their first job here had been to take scans and sediment samples. Dieter Holm and his team had been working round the clock to analyse this new data and build a three-dimensional profile of the wreck-mound from it, so that they’d have a better idea of how to go in. Tonight, therefore, was the start of the salvage proper, and Knox felt a peculiar kind of excitement he hadn’t felt in a good two years.
This room was where most of the press and TV interviews were given, so Ricky had hung the walls with props: portraits of Zheng He, artists’ impressions of his fleet, photographs of artefacts on the sea-bed and reproductions of medieval world maps. Knox stopped before one of these now. It was known, rather optimistically, as the Zheng He map, and it showed both hemispheres of the world, with Asia, Africa and Europe in one, America in the other. Though it dated from the eighteenth century, Ricky and many others were convinced it was a copy of an earlier map, made by Zheng He himself in around 1420; and that it therefore provided compelling evidence that the Chinese had found and mapped America. Knox might have been more open to this dating had it not been for the use of Mercator projections a hundred years before Mercator had even devised them, and the presence of the word ‘America’ thirty years before Amerigo Vespucci had been born.
‘Ron’s threatening us with another bloody curry tonight,’ said Miles, scrunching up a fresh sheet of paper.
‘Hell,’ said Knox. ‘I only just got my stomach back from last time.’ He moved along to a photograph of the wreck-mound. It was extraordinary the progress marine archaeology had made these past few decades, but it hadn’t all been good. The arrival of deep-sea technologies had enabled enterprising treasure hunters to track down and then plunder the richest wrecks, indifferent to their historic value. A backlash had started and international agreement had been reached, forcing modern salvagers to pay far more care and attention to the wrecks themselves, not just their cargoes. As a consequence, the basic processes of wreck-site formation were now pretty well understood. This wreck, for example: it was a fair bet that it had sustained a hull breach on the nearby reef. It would have had to have been severe, because the Chinese had used sophisticated watertight bulkheads to limit damage. Hull breaches typically sank ships in one of two ways. Either the weight of water would put such extra stress on the hull that the stern would simply snap off from the bow; or, more commonly, the water would wash from side to side, making the ship roll ever more violently on the waves, until finally it would reach its tipping point and so capsize. Artefacts would spill from its deck as it sank, leaving a scatter-pattern on the seabed, just like the one they’d found here; while the ship itself would be pinned to the bottom by its ballast, ironwork and cargo. Prevailing currents would push sediment up against it, like snowdrifts against a wall. They’d also ratchet up the stress on the hull’s caulked timbers until they snapped, exposing their unprotected innards. Barnacles, wood-boring molluscs, soft-rot fungi and cavitation bacteria would go to work. In seas this warm and fecund, the hull would quickly rot, as would any textiles, food, human and animal tissue and other organic material, leaving behind the merest traces of themselves. And, as the walls separating the internal holds and compartments rotted away, all the metal and stone artefacts would tumble together into one vast undifferentiated heap, like the grave goods of some warrior king buried beneath a great tumulus of sand, precisely like the one pictured right here, sixty metres beneath the sea.
The door opened abruptly and Dieter Holm strode in. He didn’t say a word, simply set down his cardboard box on the table, then turned on his laptop. He was short and slight, with gelled-back silver hair, gold-rimmed halfmoon spectacles and a sharply pointed white beard that suggested he rather fancied himself a bit of a devil. He had an outstanding reputation as a marine scientist, and Knox had been eager to meet him; but he’d barely arrived aboard the Maritsa before throwing a dreadful tantrum about his quarters and the constricted lab space. Knox didn’t altogether blame him, for Ricky had promised a state-of-the-art salvage ship, and the Maritsa was hardly that; but his reaction had still been pathetically over the top, leading his team straight back to Morombe, where they’d taken over a villa and set up shop.
The door opened again, and Ricky came in, followed by Maddow the Shadow. Knox couldn’t help but wonder if he’d been lurking outside, for he had a remarkable knack of being the last to arrive at any meeting. ‘Great,’ he said, taking a chair. ‘You’re all here. Then let’s get straight
