ONE
Ghost
The orchid was a Ghost: the rarest in the world. Perhaps even among the most priceless. It should have been nestling high in the Florida Everglades, not resting trapped in the fork of an anonymous African freshwater mangrove overlooking the sullen heave of the Great River on the lower edge of the inner delta in the newly recognized West African state of Benin la Bas.
Like thirty generations of its ancestors, the orchid had been seeded in the distant, derelict wreck of a greenhouse away in the montane high forest of the impenetrable jungle that clothed the slopes of a ridge of volcanoes a thousand miles inland. What little was left of the greenhouse stood beside the mouldering, overgrown framework of a long-abandoned facility on the shores of a lake that occupied one of the smaller bowl-shaped calderas on the side of Mount Karisoke, greatest of the volcanoes.
In the long-ago boom years of the seventies, when there had been high hopes that the heart of Africa would make much of the continent and more of the world rich, a Japanese company created the facility. They built dams and sluices to control the flow of the young river running through the lake, seeded the warm, shallow, volcanic waters with oysters and drew up plans to harvest freshwater pearls. Not just any workaday Mikimoto freshwater pearls, so popular at the time. For the lake was silted with rich jet and ebony volcanic mud, and the oysters that crowded the fecund beds would in time, it was hoped, produce lustrous, priceless, pure black pearls.
The man in charge of the project, Dr Koizumi, was an avid collector of orchids. He persuaded the engineers working on the dam system and the facility to build him a greenhouse and orchidarium where he could propagate his priceless collection of fragrant Japanese Fu Rans and Indonesian Dendrobium thyrsiflorums as well as his other, rarer specimens like the Ghost.
But before the first pearl could even be harvested, the facility fell victim to the first of the civil wars that raged through central Africa in the eighties and nineties. Dr Koizumi’s skeleton now lay scattered somewhere beneath the ruins of the greenhouse as those of his colleagues were buried under the mouldering facility, or strewn down the slopes towards the black lake shore. The company cut its losses as swiftly as the rebel soldiers cut their throats.
The local villages also vanished during the succeeding decades, their inhabitants scattered, slaughtered or kidnapped by restlessly marauding armies, carried away to become soldiers, sex-slaves or sacrifices. The jungle returned, empty of all but animal life — and that, too, began to die away as the rapacious, well-armed legions turned to bush meat, and then to cannibalism. The black lake passed back into half-forgotten legend and so did the black pearls it was supposed to have contained.
By the turn of the millennium, there seemed to be nothing in the whole area except the tall trees, the ruined habitations and the timeless forest spirits which had been worshipped here between the mountains and the distant coast for most of the two millennia preceding 1999. The spirits of Obi, led by the snake god Obi himself, which governed the tribes while they still lived here — and also went west with the slave ships as Obeah: voodoo. Went west, but remained here also, as is the nature of gods and spirits, alone and unworshipped. Growing hungry, perhaps, like the swarming armies that came and went through the ruined countries, looking for human sacrifice.
And Dr Koizumi’s body, facility and orchidarium remained here also, undisturbed and apparently forgotten, for more than thirty years in the lost heart of that vast, vacant darkness. And, even without the tender care that the good doctor had hoped to lavish upon them, the orchids flourished through generation after generation.
Until the rains came.
That year, in a vicious meteorological irony, all the areas of the East, from Somalia to Uganda, Tanzania and Sudan, where huge populations tried to scratch a living, were all but destroyed by drought. But on the empty and forsaken forests of the interior, five years’ rainfall tore down in less than a month. The upper slopes of the dormant volcano became deadly mudslides as even the tallest jungle trees began to lose their grip. The young river grew to a raging torrent almost overnight. The carefully constructed lake burst through the ancient, unmaintained dam system and added to the burgeoning river-spate. A wall of black water carried with it boulders of shattered cement, gallons of black slime, much of Dr Koizumi’s greenhouse and a range of his orchids which rode the strange grey crest. Topmost amongst them, the Ghost.
Further downstream, where the river at last left Karisoke’s mountain slopes, it plunged over a low, wide waterfall. At the foot of the fall there was a massive, almost circular lake, its surface a solid mat of water hyacinth, sufficiently abundant to have leeched almost all the oxygen from the water beneath it and to have killed off those few marine life forms that hadn’t been caught and eaten by the passing armies.
The debris from the lake shore smashed the lethal mat of plants apart and the power of the raging torrent sent the whole lot spinning out of the lake, on downstream. The river, which carried half as much water as the Nile, had simply been called the Great River by the long-vanished villagers who had once peopled its shores. And then the River Gir by variously coloured explorers, taking the name from records made by the earliest Roman mapmakers. Here, in strange matted islands, the water hyacinth was swept on downstream towards the distant coast, the better part of seven hundred miles away. A shore which lay beyond an outer and an inner delta which had been the death of almost every explorer seeking to come east and north upstream; from the earliest Arabic and Portuguese traders to the Elizabethan slave-traders and hardy Scottish and American missionaries. The Romans, the Bedou and the wise Mandingo traders came south and west through the Sahara — and most of them survived to tell the tale.
The Ghost, also coming south and west, survived like the itinerant Mandingo traders — for the moment at least. Caught in the thickly tangled structure, the battered orchid sat high on the greenery, surrounded by other, less fortunate blooms, which were drooping, torn and broken. Most of the concrete boulders had sunk on to the lake bed at the floor of the waterfall, tearing the mat of hyacinth loose as they did so. But the hyacinth was robust enough to be buoyant still, even in smaller clumps; sufficiently strong to be carrying odds and ends from the increasingly distant facility. Wooden planks and metal struts from the greenhouse. Bunches of black vegetation from the bed of the ruptured lake. Bizarrely, Dr Koizumi’s skull, apparently keeping close watch on his beloved orchids with the wide-gaping sockets of its eyes, grinning eerily at the sight of their survival.
The normally stately flow of the Great River Gir was enhanced not only by the flood from the slopes of the great volcano, but by the fact that the rains continued to pour on to the empty forests through which it was now flowing. The river spread itself into a series of meanders and lakes big enough to pass for inland seas, but still its flow remained fearsome under the unrelenting deluge that thundered down, day after day after day.
The Ghost, with its watchful keeper, swept swiftly onwards, therefore, through what had once been prosperous farms and plantations. Past the ruins of fishing villages and mining towns, which, like Dr Koizumi’s facility, had flourished in the seventies only to die during the relentless onslaughts of the eighties and nineties. Every now and then there would be something newer — projects that had died at birth under the dead hand of the bribe-crippled kleptocracies that had run the place through into the noughties and early twenty-tens, before the IMF, World Bank, and interested economies from Chile to China, discovered the hard way that money invested in Central Africa was even more at risk than money invested in Iceland, Ireland, Greece and Portugal.
