Instantly the rhino spun around and launched its huge grey body in a full and furious charge at the sound. The bush opened as though before a centurion tank, and the clattering, crashing charge dwindled swiftly as the rhinoceros kept going up the side of the hill and over the crest in search of an adversary. Craig sat down heavily in the middle of the path, and doubled over with breathless laughter in which were echoes of mild hysteria.

Within the next few hours, Craig had found three of the pans of stinking, stagnant water that these strange beasts prefer to the clean running water of the river, and he had decided where to site the hides from which his tourists could view them at close range. Of course, he would furnish salt4icks beside the waterholes to make them even more attractive to the beasts, and bring them in to be photographed and gawked at.

Sitting on a log, beside one of the waterholes, he reviewed the factors that favoured his plans. It was under an hour's flight from here to the Victoria Falls, one of the seven natural wonders of the world, that already attracted thousands of tourists each month. It would be only a short detour to his camp here, so that added little to the tourists" original airfare. He had. an animal that very few other reserves or camps could offer, together with most of the other varieties of gawe, concentrated in a relatively small area. He had undeveloped reservations on both boundaries to ensure a permanent source of interesting animal life.

What he had in mind was a champagne and caviar type of camp, on the lines of those private estates bordering the Kruger National Park in South Africa. He would put up small camps, sufficiently isolated from each other so as to give the occupants the illusion of having the wilderness to themselves. He would provide charismatic and knowledgeable guides to take his tourists by Land, Rover and on foot close to rare and potentially dangerous animals and make an adventure of it, and luxurious surroundings when they returned to camp in the evening air-conditioning and fine food and wines, pretty young hostesses to pamper them, wildlife movies and lectures by experts to instruct and entertain them. And he would charge them outrageously for it all, aiming at the very upper level of the tourist trade.

It was after sunset when Craig limped back into his rudimentary camp under the wild figs, his face and arms reddened by the sun, tsetse-fly bites itching and swollen on the back of his neck, and the stump of his leg tender and aching from the unaccustomed exertions. He was too tired to eat. He unstrapped his leg, drank a single whisky from the plastic mug, rolled into his blanket and was almost immediately asleep. He woke for a few minutes during the night, and while he urinated he listened with sleepy pleasure to die distant roaring of a pride of hunting lions, and then returned to his blanket.

He was awakened by the whistling cries of the green pigeons feasting on the wild figs above his head, and found he was ravenously hungry and happy as he could not remember being for years.

After he had eaten, he hopped down to the water's edge, carrying a rolled copy of the Farmers" Weekly magazine, the African farmers" bible. Then, seated in the shallows with the coarse-sugar sand pleasantly rough under his naked backside and the cool green waters soothing his still aching stump, he studied the prices of stock offered for sale in the magazine and did mental arithmetic with the figures.

His ambitious plans were swiftly moderated when he realized what it would cost to restock King's Lynn and Queen's Lynn with thoroughbred blood stock The consortium had sold the original stud for a million and a half, and prices had gone up since then.

He would have to begin with good bulls, and grade cows slowly build up his blood lines. Still, that would cost plenty, the ranches would have to be re-equipped, and the development of the tourist camp here on the Chizarira river was going to cost another bundle. Then he would have to move the squatter families and their goats off his grazing the only way to do that was to offer them financial compensation. Old grandfather Bawu had always told him, "Work out what you think it will cost, then double it. That way you will come close." Craig threw the magazine up onto the bank, and lay back with only his head above water while he did his sums.

On the credit side, he had lived frugally aboard the yacht, unlikea lot of other suddenly successful authors.

The book had been on the bestseller lists on both sides of the Atlantic for almost a year, main choice of three major book-clubs, translations into a number of foreign languages, including Hindi, Reader's Digest condensed books, the T! series, paperback contracts even though at the end, the taxman had got in amongst his earnings.

Then again he had been lucky with what was left to him after these depredations. He had speculated in gold and silver, had made three good coups on the stock exchange, and finally h! transferred most of his winnings into Swiss francs at the right time. Added to that, he could sell the yacht. A-month earlier he had been offered a hundred and fifty thousand dollars for Bawu, but he would hate to part with it.

Apart from that, he could try hitting Ashe Levy for a substantial advance on the undelivered novel and hock his soul in the process.

He reached the bottom line of his calculations and decided that if he pulled out all the stops, and used up all his lines of credit, he might be able to raise a million and a half, which would leave him short of at least as much again.

"Henry Pickering, my very favourite banker, are you ever in for a surprise!" He grinned recklessly as he thought of how he was planning to break the first and cardinal rule of the prudent investor and put it all in one basket. "Dear Henry, you have been selected by our computer to be the lucky lender of one and a half big Ms to a one-legged dried-up sometime scribbler." That was the best he could come up with at the moment, and it wasn't really worth worrying seriously until he had an answer from Jock Daniels" consortium. He switched to more mundane considerations.

He ducked down and sucked a mouthful of the sweet clear water. The Chizarira was a lesser tributary of the great Zambezi, so he was drinking Zambezi waters again, as he had told Henry Pickering he must. "Chizarira" was a hell of a mouthful for a tourist to pronounce, let alone rem em her. He needed a name under which to sell his little African paradise.

"Zambezi Waters," he said aloud. "I'll call it Zambezi Waters," and then almost choked as very close to where he lay a voice said clearly. "He must be a mad man." It was a deep melodious Matabele voice. "First, he comes here alone and unarmed, and then he sits amongst the crocodiles and talks to the trees!" Craig rolled over swiftly onto his belly, and stared at the three men who had come silently out of the forest and now stood on the bank, ten paces away, watching him with closed, expressionless faces.
