The toilet completed, they slipped out, and, by dint of traversing unsavoury alleys and skulking close under walls, managed to evade various sentries and reach the desert unchallenged. The Mirza made straight for the spot where he had picketed the ponies, and directed their course rather to the south of the hill which commanded the town on the west. The route on this occasion did not lead through the open desert, but up and down hill-paths and dry nullahs, and Ferrers wondered where they would find themselves at last. When they reached a kind of cave in which the Mirza remarked that they must leave the ponies, they were in a part of the hills with which he was totally unacquainted, so far as he could tell in the darkness. The Mirza seemed to know the way well, however; and warning him that the slightest noise would be dangerous, as the Sheikh-ul-Jabal’s servants kept the neighbourhood closely patrolled, led him up what seemed a goat-track in the rocks. He would not allow any loitering for rest, saying that the moon would soon rise, and they must be in shelter first, and by dint of great exertions they reached their goal in time. It was a kind of ledge or shelf on the side of the cliff, overlooking what seemed to be a pile of huge rocks below; but as the moon rose, Ferrers perceived that the apparently shapeless masses were the rude towers and buildings of a hill-fort. The site had been well chosen, for, with the short range of the native matchlocks, it could not be commanded from any of the surrounding hills. From his position Ferrers could see between two of the towers down into the courtyard, and he was startled to perceive a black horse standing saddled in front of the building which represented the keep or chief apartments of the place. The horse was held by a servant, and presently another servant appeared with a torch, and a third brought a bag of food and a skin of water, and fastened them to the saddle. Then, as Ferrers watched, there appeared on the threshold the majestic figure in white and scarlet which he had last seen at the pir’s tomb. The Sheikh turned for a moment, apparently to give directions to several women, the flutter of whose robes could be seen by the torchlight, and then came out upon the steps, followed by three children, two boys and a girl, whose ages might run from ten to twelve. All three kissed the Sheikh’s hand, the boys holding his stirrup while he mounted, and he gave them his blessing as he rode away. In the clear mountain air the opening of the gate in the entrance-tower was plainly audible, and presently a gleam of white and scarlet and steel beyond the fort showed that the Sheikh was riding down the path. Ferrers stood up, in a state of anger which surprised himself.

“What does it mean?” he demanded. “Who are those children?”

“It is for you to say, sahib. As for me, I have no doubt. They are the children of the Sheikh-ul-Jabal.”

“Which means that Keeling is married to a native woman, and they are his children,” said Ferrers. “Is it conceivable that a man can be such a traitor? False to his country and his race! I say, Mirza, let us go after him and put an end to his treachery.”

But the Mirza held him back. “Nay, sahib, it must not be. Has it not often been told me that the way of the English is to do all things slowly and according to forms of law? You know how the traitor can be punished after the English manner; then do not act as would one of the hill-people, which can only harm yourself.”

Ferrers saw the force of the reasoning, and followed his guide slowly down the dangerous path. His mind was in a whirl. Marriages between Englishmen and native women were far more common in those days than in these, but Major Keeling was the last man he would have expected to contract one. This, then, was the explanation of his insensibility with regard to Penelope! But he had sat beside her, talked to her, touched her hand, behaved like an honourable man who was free to seek her if he chose, while only a few miles off his unacknowledged wife and children were leading a secluded existence within stone walls. It occurred to Ferrers that it would be a good idea to arrest them and bring them to Alibad, there to confront Major Keeling with them suddenly; and he asked the Mirza whether the fort was well defended. The Mirza assured him that not only was the garrison ample for defence, but watchmen were posted on all the hill-tops round, and it was only by bribing one of these, over whom he had obtained some hold in the past, that he had been able to reach the point of vantage they had occupied. It was practically impossible to approach the place undetected, he said, and before long there came a startling proof of the truth of his words. Just before they reached the cave where the horses had been left, Ferrers trod on a loose stone, which rolled down the hillside with a terrifying clatter. Instantly a hail from the hill on their left was answered by another from the right, and followed by one from the fort itself.

“Mount and ride for your life,” panted the Mirza to Ferrers, as they stumbled into the cave. “There is no hope of escaping unnoticed now.”

They had the ponies outside the cave in a twinkling, and were mounted and riding down the path in another second. Stones rolled down under the ponies’ feet, voices ran from hill to hill, and presently, when the forms of the intruders were perceived, bullets began to fly around them. Fortunately for Ferrers and the Mirza, the ponies were sure-footed, and none of the Sheikh’s matchlockmen waited to take good aim. They dashed out on the plain at last, unhurt, and from the nullah behind them there rang out a last shot and a sharp cry, a man’s death-cry.

“The sentry who suffered us to pass,” remarked the Mirza casually. “They have a short way with brethren who have been false to their oaths, as I should know.”

He seemed to feel he had said too much, and refused to answer Ferrers’ eager questions as to when he had been a member of the brotherhood, and why he had left it. They rode briskly back to the outskirts of the town, and dismounted. The Mirza guided Ferrers through the byways to Colin’s quarters, and left him there, carrying off his disguise for safety’s sake, and Ferrers tumbled into bed and slept heavily.
