So quickly was this done, so absolutely terrifying was his abrupt and wholly unlooked-for turn in the state of affairs, that his glance was hardly quick enough to mark the paper disappearing through the open window beside which he was seated, or the black, claw-like hand which had seized it. Yet he did only just see both.

He fell back in his chair in a cold sweat. Such a thing to happen in the dead midnight, with not a soul but himself astir. Small wonder that, unnerved by the dastardly act of robbery he had just committed, his thoughts should revert straight to Satan himself. The sick man was still slumbering peacefully.

Recovering his nerve to some extent, he rushed to the door and gained the outer air. All was still as death. As his sight became used to the modified gloom of the starlight he went round to the back of the house—made the complete circuit of it. Not a living thing was astir. He went even further afield, peering here, there, and everywhere. In vain. Then, with nerve and system shaken as they had never been before in his life, he returned indoors.

For long he sat motionless, pondering over this extraordinary occurrence. The first shock of surprise, the first involuntary access of superstition past, two considerations obtruded themselves. The prospect of possible wealth had been snatched from his grasp, literally strangled at its birth, for the paper looked genuine, and was certainly lucid enough, but it required studying, and that carefully. For the rest, how should he eventually account to its owner for its disappearance? And at this thought he began to feel exceedingly uncomfortable.

Not for long, however. The bag could easily be replaced, and the chances were that its owner would take for granted the security of its contents, and not go to the trouble of opening it to ascertain. Or he himself might be far enough away by that time, but that he was loth to abandon a fellow-countryman on a lonely sick-bed in that frightful wilderness; and we must, in justice to the man, record that this consideration was genuine and wholly untinged by his own reluctance to turn his back on the place until every effort to recover the precious document had been tried. Should, however, the worst come to the worst, and Renshaw be moved to assure himself of the safety of his secret, what could be easier than to persuade him that he had himself insisted on destroying it in his delirium?

He rose softly to hunt for a needle and some twine. Having found them he re-stitched the pouch, carefully copying the mode of stitching which had held it together before. Then he went over to the bedside to re-fasten it to the sick man’s neck.

This was no easy task. Poor Renshaw began to grow restless again, as though a glimmer of inspiration across his clouded and enfeebled brain warned him that his cherished secret had been tampered with. At last, however, through the exercise of consummate patience and care, the thing was done.

With a feeling of relief the stranger once more sought the outer air.

“What a fool the man must be!” he said to himself. “From the date of that paper he must have been in possession of the clue for at least two years, and yet he hasn’t turned it to account. The place should be easy to find, too; anyway, I’ll lay a guinea I’d have ferreted it out long before this. Rather! Long before!”

Thus he decided, overlooking the trifling probability that if Renshaw Fanning, with lifelong experience as a hunter, treasure-seeker, and adventurer in general, had failed to hit upon the mysterious locality, it was hardly to be supposed that he, Maurice Sellon, new arrival in South Africa, who, for instance, had been unable to travel across the Karroo plains without losing himself, would fare any better.
