“Major Keeling, I earnestly entreat you to grant me this six months. I cannot leave Ferrers to his fate.”

“What are you standing there talking for—taking up my time? You won’t do any good if you stay till to-morrow.”

“He is my friend. I must try to save him.”

“And your brother-in-law that is to be? It makes no difference.”

“No, sir, that is not my reason. In fact, my sister has determined to break off her engagement, and I shall have to tell him so, but——”

Major Keeling sprang up furiously. “What do you mean by coming here and trying to tempt me, sir? You shall not go to your death for Ferrers or any one else, unless it’s in the way of duty. Be off!”

Nothing but the enlightenment which broke suddenly upon Colin would have sufficed to make him leave the office without irritating the Commandant by further argument, but for a moment the discovery overshadowed in his mind even the thought of Ferrers. He had felt some natural curiosity as to the identity of the man whom Penelope preferred to his friend; but as she did not offer to gratify it he had not pressed her, thinking that Porter was almost certainly the person in question. Now it occurred to him that Penelope might be of use in asking for the leave which Major Keeling was so determined not to grant, but he repressed the thought sternly. He would do nothing that would allow Penelope or any one else to think that he recognised the slightest bond between her and the man who had supplanted Ferrers.

Leaving the office, he saw Sir Dugald riding past, and joined him, telling him of the unsuccessful issue of his application. Sir Dugald, who may have been primed beforehand by Penelope, was much rejoiced, and inwardly blessed Major Keeling’s wisdom, but was careful not to hurt Colin’s feelings.

“It would mean certain death for you, after all,” he said; “and you have your sister to think of, you know. Why not see what money can do? Let us go and see that old sinner Saadullah. He might be able to make inquiries for you, and he starts for Gamara in a week or two.”

They rode out to the piece of land on the north of the town which had been set apart as a camping-ground for traders and small bands of nomads, and threaded their way between the lines of squalid tents and through the confusion of camels, horses, and human beings, towards the encampment of Saadullah Kermani, which was somewhat withdrawn from the rest. Most of the men who were hanging about saluted the two officers with more or less goodwill, but a hulking fellow who was lounging against a pile of merchandise stared at them open-mouthed, and on being hastily prompted by a neighbour as to his duty, burst into an insolent laugh. Sir Dugald turned his pony sharply aside, and seizing the man by some portion of his ragged garments, shook him until his teeth chattered, then released him and ordered him to beg pardon unless he wanted a thrashing. Forced to his knees by his companions, the man stuttered out some kind of apology, adding in a sulky murmur something that the Englishmen could not hear.
