She continued: "Wilfred heard that Van Zwieten was at the cottage, and kept a sharp eye on Malet. He found out that he was to meet Van Zwieten on that night and give him some documents. He then made up his mind to kill him, to save--as I have said--the honor of the family, as well as to punish him for his wickedness in betraying his own country. "Shortly before nine o'clock, Van Zwieten came to the Manor and entered the library by one of the French windows. It was his voice that Lady Jenny heard when she went to see if her husband was back from his walk. Indeed, it was Malet who brought Van Zwieten to the library to give him the papers. When Lady Jenny was on her way to the Rectory to see you, Harold, Wilfred escorted her. She mentioned that she had heard voices in the library, and wondered with whom her husband had been speaking. Wilfred guessed at once that the man was at his scoundrelly work, and was more than ever determined to put a stop to it. To get away from Lady Jenny without exciting her suspicion, and also to prove an _alibi_ in case he shot the man, he pretended to sprain his ankle. Lady Jenny was quite unsuspicious, and went on to the Rectory alone. As you know, she never reached it, having been stopped by the storm. As soon as she was out of sight, Wilfred hastened back to the house with the intention of confronting both men, and killing Malet if he did not take the papers back from Van Zwieten. He also entered the library by the French window, so the servants never saw him come in. He found the room empty, as Van Zwieten had gone away, and Malet with him--I suppose it was to receive further instructions. Wilfred saw the revolvers belonging to Harold on a side-table, for Mr. Malet had been using them that afternoon. He took one, found that it was loaded, and hastened after the pair. Knowing that Van Zwieten was at our cottage, he went first in that direction; but for a long time he could see neither of them. At last he caught sight of Malet in the orchards, just before the storm. He was talking with a man whom Wilfred took to be you, father." "My brother, I suppose?" "Yes," replied Brenda. "It was Uncle Robert. He heard high words between the two and saw the struggle." "That was when the crape scarf was torn?"
