Harold returned from his patrolling, but only for a short while. Again and again he was sent out, sometimes into the enemy's country, and he was in the saddle from morning till night. Brenda saw but little of him, and had to put up with his continued absence as best she could. She had, as it happened, plenty of work to distract her. She was an excellent nurse, and did good service in the hospital, not sparing herself in any way. Indeed, so constantly was she employed, that the doctor insisted upon her taking a sufficient amount of exercise, and strongly advised her to ride. This commended itself to her, for she rode well and was never happier than when in the saddle. She managed to obtain a habit from a colonial lady who was also in the camp. Her husband managed to procure for her a capital little animal--one of those active little ponies used by the Boers. And so she came to make frequent excursions into the surrounding country.
"You must keep on this side of the river, Mrs. Burton," said the doctor. "As long as you do that you are quite safe, even beyond the camp lines. But don't cross the Tugela. Directly you do that you run risks. I can't afford to lose my best nurse, you know."
Brenda looked at the sullen waters of the stream rolling through the melancholy veldt, and laughed. "I should be a clever woman to cross that river, doctor, even if I wanted to. You may depend upon my taking every care of myself. I shall keep on the right side from sheer inability to get on the wrong one."
But it was not often that Brenda was allowed to ride alone. She was not the sort of woman to have to seek a cavalier. But as the time drew near when the General intended to make his move, his juniors found they had very little leisure, and she had perforce to ride alone. But even so she had no fear, though her father worried a good deal about her. But as she always returned safely, even he grew gradually accustomed to see her go off unattended.
Every now and again there came upon her a feeling that she was being watched. She would look round and see a Kaffir staring fixedly at her. This happened on several days in succession. Yet she could not be sure that it was always the same man. The natives were all so very much alike to her that it was impossible to distinguish one from another. However, this espionage was in nowise aggressive; on the contrary, if espionage it were, it was done very skillfully. It might be even pure fancy on her part, for ever since that meeting with Van Zwieten in Durban her nerve was anything but steady. At all events, she decided not to say anything to her husband about it lest he should forbid her excursions altogether, and now that she had taken to riding again she was very loth to give it up.
She wondered if it might be possible that Van Zwieten was about. It was possible--just possible, but she thought not probable. He would know that Wilfred was in the camp, and that he would have no hesitation in denouncing him as a spy; and for that reason she did not think he would be so foolish as to trust himself within the British lines. At least so long as she kept on this side the Tugela he could not molest her. He was no fool to risk his life in a mad attempt which would mean certain failure. So she comforted herself. But the feeling of being watched still remained with her.
At last the order to advance was given, and the men, tired of inaction, joyfully obeyed. Harold had been absent two days on scout duty this time across the river which Warren's brigade were preparing to negotiate. He had been sent out with a small force to make a reconnaissance in the enemy's country. She was beginning to feel rather anxious for his return. Despondent and full of vague foreboding as she was, she fancied that a ride would do her good, and she set out as usual, somewhere about sundown. She intended to go only a short way and return before it grew dark. The Kaffir who saddled her horse watched her ride out of the camp and grinned evilly.
Behind the rugged mountains the sky was a fiery red, and was barred with black clouds. The air was hot and sultry, and there was promise of a storm in those heavy masses lying in the east. Under the crimson glare the veldt looked grim and ominous. The kopies stood up like huge gravestones; and where the grass failed, the sandy karoo, even more barren, took its place. Here and there were farmhouses with red walls and corrugated outbuildings, and the dull red light bathed the lonesome scene as if in blood. The oppressive feeling in the air recalled to Brenda's mind that memorable night at Chippingholt when Malet had been done to death. Just such another storm was impending. She began to feel nervous as the recollection came upon her and she decided to return.
For some time her pony had been restive, tossing his head and champing his bit. He was usually so quiet that she could not understand it, but just then, as she had made up her mind to return, he grew even more distressed and finally he bolted. She let him have his head and in nowise lost hers. She would be able to pull him up after a few miles. On he galloped, the bit between his teeth, raising the loose red sand, and taking her further and further away from the camp; past kopjes, past Kaffir huts, stone walls, sheep kraals, he tore. She made several attempts to check him, but in vain. Suddenly he put his foot into a hole, stumbled, and sent her flying over his head. She lay on the ground half stunned. The pony, relieved of his burden, scampered off. She was able to realize that she was there alone--on the karoo, far from the camp, and with night just upon her.
