"I promise. But if you fail with her, then I must see her."

"Yes, if I fail, but I won't fail. You have put a weapon into my hand. After I have seen her, I will tell you the whole miserable business. We will get the better of Van Zwieten yet, my darling."

Captain Burton was picking up his spirits. He went away in a more cheerful frame of mind. Brenda felt certain that his refusal to speak was in the interest of Lady Jenny. Could she have fired the shot? But that seemed impossible. If she herself were guilty, how could she silence and thwart Van Zwieten, who appeared to know so much about the crime? What with her father's denials, Harold's silence, and Van Zwieten's threats, Brenda was quite bewildered. What would be the outcome of it all? she wondered.

Having promised Harold not to see Lady Jenny, Miss Scarse cast about in her mind as to who else could assist her in thwarting Van Zwieten. From her father no help could be obtained. He was wholly on the Dutchman's side, and, it would appear, under his thumb. Then she thought of Wilfred and his openly-expressed hatred of Van Zwieten. Could she not make use of that? In the present state of popular feeling a Boer spy would have a bad time if found in London. If Wilfred could discover that Van Zwieten really was on the Secret Service Staff of the Transvaal, he could force the Dutchman to leave England under threat of denouncing him to the authorities.

No sooner had she come to this conclusion than she acted upon it, and wrote a note to Wilfred's London address asking him to call. Having posted it, she returned to the drawing-room to make tea for Aunt Judy, who had just got back from her shopping. The colonel was still absent, so the two ladies settled themselves down to the discussion of chiffons. If there was one thing Mrs. St. Leger was fond of it was dress. As for Brenda, her mind was too much preoccupied with her own troubles to care much for fashions or bargains. But strive as she might to hide her indifference, it did not take her aunt long to see that her interest was assumed. But that she put down to her lover's visit.

"Why didn't he stay to tea?" she asked, putting away her purchases.

"Because he had to get back to Aldershot," replied Brenda, pouring out the tea. "They are very busy down there."

"Oh, Brenda, do you think there will be war? How glad I am that William has retired."

"That is not the speech of a true soldier's wife, Aunt Judy."

"My dear, it's all very well talking," replied Mrs. St. Leger, testily, "but you don't know what war is. I don't mean these little frontier skirmishes, but a real war--that is truly terrible. I remember the Crimea."
