A rare cloud blotted the moon a half hour after they started marching again, and when it passed, the shifting illumination caused something on the desert floor to catch Ryder’s eye. According to his compass and the stars, he’d been following a due-westerly direction, and none of the men commented when he suddenly turned north. He paced ahead of the others, aware of the flaky soil crunching under his boots, and when he reached the spot he dropped to his knees.

It was merely a dimple in the otherwise flat valley, no more than three feet across. He cast his gaze around the spot, smiling tightly when he found bits of broken eggshell, and one that was almost intact except for a long crack that ran like a fault line along its smooth surface. The shell was the size of his fist and had a neat hole drilled through the top. Its stopper was a tuft of dried grass mixed with native gum. It was one of the San’s most prized possessions, for without these ostrich eggs they had no way to transport water. That one broke when they were refilling could have very well doomed the party of Bushmen who last used the well.

H. A. almost felt their ghosts staring down on him from the ancient riverbed’s bank, tiny little spirits wearing nothing but crowns of reeds around their heads and rawhide belts festooned with pouches for their ostrich eggs and quivers for the small poisoned arrows they used to take game.

“What have you found, H. A.?” Jon Varley asked, kneeling in the dirt next to the guide. His once shining dark hair fell lank around his shoulders, but he had somehow maintained the piratical gleam in his eyes. They were the eyes of a desperate schemer, a man driven by dreams of instant wealth and one willing to risk death to see them fulfilled.

“Water, Mr. Varley.” Though twenty years his senior, H. A. tried to speak deferentially to all his clients.

“What? How? I don’t see anything.”

The Watermen brothers sat on a nearby boulder. Peter Smythe collapsed at their feet. Tim helped the lad move upright so his back was against the water-worn rock. His head lolled against his thin chest and his breathing was unnaturally shallow.

“It’s underground, like I told you.”

“How do we get it out?”

“We dig.”

Without another word the two men began scraping back the soil that a Bushman had laboriously used to refill the precious well so that it didn’t dry out. H. A.’s hands were broad and so callused that he could use them like shovels, tearing into the friable earth with little regard to the flinty shards. Varley had the hands of a gambler, smooth and, at one point, neatly manicured, but he dug just as hard as the guide — raging thirst allowing him to ignore the cuts and scrapes and the blood that dripped from his fingertips.

They excavated two feet of earth and still no sign of water. They had to expand the hole because they were much bigger than the Bushmen warriors whose job it was to dig these wells. At three feet H. A. took out a scoopful of dirt and when he dropped it away from the hole a thin layer clung to his skin. He rolled it between his fingers until he’d produced a little ball of mud. When he squeezed it a quivering drop of water shone in the starlight.
