Piet Maartens was evidently put out, but he knew Mr Hunter to be a man who was not to be trifled with, and with a muttered oath he turned on his heel and strode out into the hall. Then he went to the door and gave a shrill whistle. Two Boer policemen, who are locally known as “Zarps”, joined him immediately, and at once commenced to search every corner of the house. Meanwhile Jack had not been idle. Once upstairs he had darted into Mr Hunter’s room and obtained possession of an old tweed suit and a muffler resembling in appearance those usually worn by the Boers. Then he hurried out and along a passage till he came to a ladder leading up through a trap-door into a large loft where the cisterns for the supply of water were kept, much as they are in England. A moment later he had scrambled up, passed into the loft, and dragged the ladder after him. As he did so he heard steps running upstairs, and lowered the trap gently just as Piet Maartens and one of the Zarps arrived at the end of the passage.

There was a moment’s silence, and then he heard an exclamation of vexation and a rapid conversation, in which he recognised a word here and there which showed him that his pursuers had already guessed his whereabouts.

But Jack was not to be so easily caught. Above his head there was a small glass skylight, and this he pushed open with the end of his ladder, and was quickly out on the roof. Mr Hunter’s house was irregular in shape, and the roof was consequently not one of those sloping ones on which there is no cover. Where Jack was he was in a small hollow, with tiles rising steeply on either side of him; and here he determined to remain as long as possible. It was already dusk, and in a few moments it would be quite dark, so that his figure would not be seen as he climbed over the top of the roof.

Placing his ladder against the steeply-sloping tiles, in readiness for a hurried escape, Jack hastily dragged Mr Hunter’s old suit on over the clothes he was already wearing. There was no difficulty about it, for though Jack was somewhat taller than his friend, the latter was stouter and broader. Soon his rough disguise was completed, and with the slouch hat on his head he looked precisely like hundreds of Boers who were to be found in and around Johannesburg.

By now it was pitch dark, and he cautiously climbed up the ladder and stared down into the garden which surrounded the house. It was illuminated in patches where the lights from the windows fell upon it, and here the figures of half a dozen Zarps stood out prominently. Elsewhere all was darkness, but by watching carefully, Jack saw first one and then as many as four other widely-separated dots of fire, which now and again disappeared, to become more prominent a moment later, clearly showing them to be the glowing ashes of the pipes which Boers one and all indulge in from morning till night, whether acting as policemen or not.

There was at least ten yards between them, and Jack at once made up his mind to attempt to reach the ground and slip away. Sitting astride the top of the roof, he lifted his ladder with the greatest caution, and lowered it again on the other side till it rested in the gutter. Then he gently pressed upon it, and finding it secure put all his weight upon it and descended. Arrived at the bottom he fixed his heels in the iron gutter, and once more lifted his ladder and passed it down till it rested upon the roof of the verandah. This, like the one upon which he was sitting, was composed of corrugated iron, and at the slightest blow gave out a sound like a drum. But fear of capture, and what that might mean, made Jack cautious. His wits were sharply alert, and he handled the light ladder with such care that once more he managed to fix it in the gutter which edged the verandah, without so much as a sound.

Seated on the roof, he waited for a few moments, watching the little glowing spots below, and noticing that they had not moved. Then he heard shouts from inside the house, a loud bang, and the trampling of feet just beneath him, which told him that Piet Maartens and his companions had secured another ladder and were already in the loft.

There was not a moment to be lost. He scrambled on to the ladder and down to the verandah roof. Then he shifted his ladder and clambered down it to the ground, and was on the point of moving off when a rough hand forced something into his mouth, preventing him from crying out, a sack was thrown over his head, and he was carried away swiftly and bundled into a four-wheeled cart, which was driven off at a rapid pace.

For the moment Jack was bewildered. But he quickly realised that after all his caution the slim Boer had been too clever for him. One of the Zarps must have seen him climbing down the roof, and now he was in their hands, a prisoner, and with what fate before him? On his wrists a pair of handcuffs had been slipped, and at either side of him sat an armed Zarp. He could tell that, for each held him by the arm as though afraid that he would still contrive to get away, while one of them clicked the lock of his revolver in a very suggestive manner close to Jack’s head.

“Well, I suppose I had better sit still and wait,” he thought. “I must try to remember the various turnings, so that I shall know where they are taking me and how to return.”
