After a time the moon rose and looked at them from over a distant ridge that was thousands of feet higher than the ragged fringe of Khyber wall. The little mangy jackals threw up their heads to howl at it; and after that there was pale light diffused along the track, and they could see so well that King set a faster pace, and they breathed hard in the effort to keep up. He did not draw rein until it was nearly time for the Pass to begin narrowing and humping upward to the narrow gut at Ali Masjid. But then he halted suddenly. The jackals had ceased howling, and the very spirit of the Khyber seemed to hold its breath and listen.
In that shuddersome ravine unusual sounds will rattle along sometimes from wall to wall and gully to gully, multiplying as they go, until night grows full of thunder. So it was now that they heard a staccato cannonade—not very loud yet, but so quick, so pulsating, so filling to the ears that he could judge nothing about the sound at all, except that whatever caused it must be round a corner out of sight.
At first, for a few minutes King suspected it was Rewa Gunga's mare, galloping over hard rock away ahead of him. Then he knew it was a horse approaching. After that he became nearly sure he was mistaken altogether and that the drums were being beaten at a village—until he remembered there was no village near enough and no drums in any case.
It was the behavior of the horse he rode, and of the led one and the mules, that announced at last beyond all question that a horse was coming down the Khyber in a hurry. One of the mules brayed until the whole gorge echoed with the insult, and a man hit him hard on the nose to silence him.
King legged his horse into the shadow of a great rock. And after shepherding the men and mules into another shadow, Ismail came and held his stirrup, with the leather bag in the other hand. The bag fascinated him, because he did not know what was in it, and it was plain that he meant to cling to it until death or King should put an end to curiosity.
King drew his pistol. Ismail drew in his breath with a hissing sound, as if he and not King were the marksman. King notched the foresight against the corner of a crag, at a height that ought to be an inch or two above an oncoming horse's ears, and Ismail nodded sagely. Whoever now should gallop round that rock would be obliged to cross the line of fire. Such are the vagaries of the Khyber's night echoes that it was a long five minutes yet before a man appeared at last, riding like the night wind, on a horse that seemed to be very nearly on his last legs. The beast was going wildly, sobbing, with straggled ears.
