"Ah! that was what the Boers call 'slim,'" he said, wincing, nevertheless, at her open contempt for him. "All's fair in love and war, you know, but your husband has been rather in advance of himself on this occasion, and the plot has failed. Yes, you see I admit that it is a plot, and I admit that it has failed." "I have nothing to say to you," said Brenda, coldly, "except to tell you that if you attempt to molest either my husband or myself further I shall have you arrested as a spy." He looked uneasily down the road and at the stern, set faces of the passing soldiers. He knew that from such men as they he might expect precious little mercy once the word spy had gone out against him, followed by damning evidence of his complicity. Boer treachery had to be avenged; there had been plenty of it about, and he did not fancy being a scapegoat for others. "My dear Mrs. Burton," he went on calmly, "I wonder you spare me at all. Why not have me arrested now and have done with it? I am completely in your power, am I not? You have but to raise your voice and the thing would be done. Indeed, I am not at all sure that I should reach the jail alive. They hate spies here, and it is true they have good reason to. You may not have such a chance again, so cry out upon me now and revenge yourself on me once and for all for my crime--my crime of loving you." "No, I will not," replied Brenda, firmly; "but I give you fair warning, Mr. van Zwieten, that if you do not leave this place immediately I shall at once inform the authorities about you. In luring me to Pretoria you made one mistake; you thought I should come unprepared. I did no such thing. I have ample evidence with me to prove that in London your occupation was that of a spy. Lady Jenny gave me the papers." "I'm very much obliged to Lady Jenny, I'm sure," he said, with a bow. "At Pretoria--for Oom Paul--you could hardly have brought credentials calculated to speak more highly in my favor. He would be quick to appreciate my services." "Why did you wish me to come to Pretoria? You know I am married." "Yes, I know you are married; but marriage can be severed as all else is severed--by death," he said significantly. "If you had come to Pretoria--but there is no need to talk about that," he broke off impatiently. "I was duly informed that your husband was missing, but he escaped before I could reach the Tugela and myself take him to Pretoria, where he would have been completely in my power. I wrote the letter thinking you would really find him there. But he escaped and got your telegram--the one you sent to Wilfred Burton. I followed him down here, and learned how he intended to intercept the _Kaiser Fritz_. You see I am well informed, Mrs. Burton."
