It was getting lighter. The moon was rising at last, and as we strained our gaze through the thick bushy screen behind which we had halted, this is what we saw.

We were looking down upon a circular pool whose surface reflected the twinkling of the stars. On three sides of it ran an amphitheatre of rock, varying from six to twenty feet in height. At the upper end where the water fell into it in a thin stream, the rock dipped to the form of a letter “V.” All this we could make out in the dim light of the stars, for as yet the face of the rock was in dark shadow. And yet, and yet—as I gazed I could descry a striking resemblance to our own waterhole except that this was more shut in.

“Remember,” whispered the Xosa, impressively. “There is to be no shooting. They are to be taken alive.”

We promised, wondering the while where “they” were. A tension of excitement, and eagerness for the coming struggle was upon all three of us. For me I rebelled against the agreement which should deter me from battering the life out of the black villains who had brought my darling to this horrible place. What terrors must she not have endured? What ghastly rites of devil worship were enacted here?

Foot by foot the light crept downwards, revealing the face of the rock as the moon rose higher and higher. Then a violent nudge from Falkner, at my side—but I had already seen.

The water was pouring down upon the head of what had once been a human being. Now it was a dreadful, glistening slimy thing, half worn away by the action of the running water. It was fixed in a crucified attitude, facing outwards, bound by the wrists to a thick pole which was stretched across horizontally from side to side of the pool, the feet resting upon a rock ledge beneath. It needed not the agonised stare upon that awful upturned face—or rather what once had been a face—to tell in what unspeakable torture this wretched being had died. To my mind and to Falkner’s came the recollection of our gruesome find that grey afternoon in the northern wilds of Zululand.

Two more bodies, one little better than a skeleton, were bound similarly on each side of the central one. As we gazed, spellbound with horror, we saw that which pointed to one of these being the body of a white man.

Now a dark figure appeared on the brink above the central victim, appeared so silently and suddenly as to lend further horror to this demon haunted spot. We watched it in curdling horror as it stooped, then reached down and cut the thongs which held first one wrist then the other. The body thus released toppled heavily into the pool with a dull splash that echoed among the overhanging rocks. Then it disappeared.

The figure, straightened up now, stood watching the troubled surface for a moment. Standing there full in the moonlight I thought to recognise the face. It was that of one of Tyingoza’s people whom I knew by sight, but could not fit with a name. Then he turned to clamber back, crooning as he did so, a strange weird song. It was not very intelligible, but was full of sibongo to the Water Spirit, who should now delight in a fresh victim, a rare victim, one by the side of which all former sacrifices were but poor. Then would the land have rain again—would drink all the rain it needed.

Now the blood seemed to rush to my brain as though to burst it. A red mist came before my eyes, and my heart seemed to hammer within me as though it would betray our place of concealment without fail. For I realised who this new victim—this rare victim—was to be, the victim who was to take the place of the ghastly shapeless horror which we had seen disappear beneath that awful surface. A warning touch from Jan Boom brought me back to recollection and sanity again.
