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.

Instead of speaking, King spurred out of the shadow and blocked the oncoming horseman's way, making his own horse meet the other shoulder to breast, knocking most of the remaining wind out of him. At risk of his own life, Ismail seized the man's reins. The sparks flew, and there was a growled oath; but the long and the short of it was that the rider squinted uncomfortably down the barrel of King's repeating pistol.

“Give an account of yourself!” commanded King.

The man did not answer. He was a jezailchi of the Khyber Rifles--hook-nosed as an osprey--black-bearded--with white teeth glistening out of a gap in the darkness of his lower face. And he was armed with a British government rifle, although that is no criterion in that borderland of professional thieves where many a man has offered himself for enlistment with a stolen government rifle in his grasp.

The waler he rode was an officer's charger. The poor brute sobbed and heaved and sweated in his tracks as his rightful owner surely had never made him do.

“Whither?” King demanded.
