HE never should have ordered them to leave the guns behind. The decision would cost them all their lives. But had there really been a choice? When the last remaining packhorse went lame they’d had to redistribute its load, and that meant leaving equipment behind. There was no debating the necessity of bringing the water flasks the animal had carried, or the satchels bursting with uncut stones. They’d had to abandon the tents, bedrolls, thirty pounds of food, and the Martini-Henry rifles each of the five men had carried, as well as all the ammunition. But even with these weight savings the surviving horses were severely overburdened, and with the sun beginning to rise once more to pound the desert no one expected their mounts would last the day.

H. A. Ryder knew better than to agree to lead the others across the Kalahari. He was an old Africa hand, having abandoned a failing farm in Sussex in the heady days of the Kimberley rush hoping to make himself a millionaire in the diamond fields. By the time he’d arrived in 1868 the whole of Colesberg Kopje, the hillock where the first diamonds had been discovered, was staked and the fields around it, too, for several miles. So Ryder turned to providing meat for the army of workers.

With a pair of wagons and hundreds of sacks of salt to cure the game, he and a couple of native guides ranged over thousands of square miles. It had been a solitary existence but one that Ryder grew to love, just as he came to love the land, with its haunting sunsets and dense forests, streams so clear the water looked like glass, and horizons so distant they seemed impossible to reach. He learned to speak the languages of various tribes, the Matabele, the Mashona, and the fierce, warlike Herero. He even understood some of the strange clicks and whistles that the Bushmen of the desert used to communicate.

He’d taken work as a safari guide so that rich Englishmen and Americans could adorn their mansion walls with trophies and he had spent time finding suitable routes for a telegraph company stringing lines across the southern third of the continent. He’d fought in a dozen skirmishes and killed ten times that many men. He knew and understood the African people and knew better still the savagery of the land itself. He knew he should have never accepted the job of guiding the others from Bechuanaland across the vast Kalahari wasteland in a mad dash to the sea. But there was always the lure of the big payoff, the siren song of instant wealth that had drawn him to Africa in the first place.

If they somehow made it, if the uncaring desert didn’t claim them, then H. A. Ryder was going to have that fortune of which he’d always dreamed.

“Think they’re still back there, H. A.?”

Ryder squinted into the rising sun so that his eyes nearly vanished into his weathered skin. He could see nothing on the distant horizon but curtains of shimmering heat that formed and dissolved like smoke. Between them and the fiery sun marched dunes of pure white sand — shifting waves that rivaled towering hurricane swells. With the sun came the wind, which lashed at the tops of the dunes so that sand blew off their crests in stinging clouds.
