It might have been objected that Ferrers was within riding distance of Alibad, and that there was no law cutting him off from his friends there; but since Colin and Penelope Ross had come up-country he had avoided the place as if it were plague-stricken. Lady Haigh had been quite right in her interpretation of his feelings, and though he had succeeded in winning over Colin to plead his cause with Penelope, he now wondered gloomily why he could not have let well alone. He was always acting on impulse, he told himself, in a way that his cooler judgment disapproved, and it did not occur to him that he had to thank the Mirza’s influence over him for this fresh change. In fact, he was not conscious of it, for the subject was never mentioned between them; but in the Mirza’s society he felt no desire for that of his old friends. He had a real fondness for Colin, the one man of his acquaintance who believed in him, though he found it terribly fatiguing to keep up in his company the pretence of being so much better than he was. Colin had no idea of his real tastes and pursuits, and, curious though it may seem, Ferrers was prepared to take a good deal of trouble to prevent his becoming aware of them. The thought that Colin’s eyes would never rest upon him in kindness again was intolerable; and if Colin alone had been concerned, his mind would have been at ease. But if he married Penelope, he must either give up the Mirza, or she must know, and therefore Colin would know, a good many things he would prefer to keep secret--and what counterbalancing advantage would there be? Though he had felt his interest in her revive when he saw her admired and courted, she was not the type of woman who could keep him in thrall: she would suffer in silence, and look at him reproachfully with eyes that were like Colin’s, and there would be little pleasure in that. At this point Ferrers’ meditations were suddenly interrupted. Intent upon his mental problem, it was with a shock that he found himself confronted by a trooper of the Khemistan Horse. He tried to discover what emergency could have dictated the posting of vedettes at this distance from the town, but learned only that it was the Doctor Sahib’s order. Wondering vaguely whether there was plague in the district, and the doctor was establishing a sanitary cordon, he rode on, to see more vedettes in the distance, and to be sharply challenged by a sentry as he entered the town. The squalid streets seemed wholly destitute of the military element which usually gave them brightness; but in the courtyard of the mud building which served as a hospital Dr Tarleton was hard at work drilling a motley band of convalescents and hospital assistants, with a stiffening of dismounted troopers, who appeared to be bored to extinction by the proceedings. “What’s up, Tarleton?” cried Ferrers, after watching in bewilderment the strange evolutions of the corps and their instructor’s energetic endeavours to get them straight.
