"Killed?" cried Ethne, and she laughed in a short and satisfied way.

Willoughby turned and stared at her, disbelieving the evidence of his ears. But her face showed him quite clearly that she was thoroughly pleased. Ethne was a Celt, and she had the Celtic feeling that death was not a very important matter. She could hate, too, and she could be hard as iron to the men she hated. And these three men she hated exceedingly.

It was true that she had agreed with them, that she had given a feather, the fourth feather, to Harry Feversham just to show that she agreed, but she did not trouble her head about that. She was very glad to hear that Major Castleton was out of the world and done with.

"And Colonel Trench too?" she said.

"No," Willoughby answered. "You are disappointed? But he is even worse off than that. He was captured when engaged on a reconnaissance. He is now a prisoner in Omdurman."

"Ah!" said Ethne.

"I don't think you can have any idea," said Willoughby, severely, "of what captivity in Omdurman implies. If you had, however much you disliked the captive, you would feel some pity."

"Not I," said Ethne, stubbornly.

"I will tell you something of what it does imply."

"No. I don't wish to hear of Colonel Trench. Besides, you must go. I want you to tell me one thing first," said she, as she rose from her seat. "What became of Mr. Feversham after he had given you that feather?"

"I told him that he had done everything which could be reasonably expected; and he accepted my advice. For he went on board the first steamer which touched at Suakin on its way to Suez and so left the Soudan."

"I must find out where he is. He must come, back. Did he need money?"

"No. He still drew his allowance from his father. He told me that he had more than enough."

"I am glad of that," said Ethne, and she bade Willoughby wait within the enclosure until she returned, and went out by herself to see that the way was clear. The garden was quite empty. Durrance had disappeared from it, and the great stone terrace of the house and the house itself, with its striped sunblinds, looked a place of sleep. It was getting towards one o'clock, and the very birds were quiet amongst the trees. Indeed the quietude of the garden struck upon Ethne's senses as something almost strange. Only the bees hummed drowsily about the flowerbeds, and the voice of a lad was heard calling from the slopes of meadow on the far side of the creek. She returned to Captain Willoughby.

"You can go now," she said. "I cannot pretend friendship for you, Captain Willoughby, but it was kind of you to find me out and tell me your story. You are going back at once to Kingsbridge? I hope so. For I do not wish Colonel Durrance to know of your visit or anything of what you have told me."

"Durrance was a friend of Feversham's--his great friend," Willoughby objected.

"He is quite unaware that any feathers were sent to Mr. Feversham, so there is no need he should be informed that one of them has been taken back," Ethne answered. "He does not know why my engagement to Mr.

Feversham was broken off. I do not wish him to know. Your story would enlighten him, and he must not be enlightened."

"Why?" asked Willoughby. He was obstinate by nature, and he meant to have the reason for silence before he promised to keep it. Ethne gave it to him at once very simply.

"I am engaged to Colonel Durrance," she said. It was her fear that Durrance already suspected that no stronger feeling than friendship attached her to him. If once he heard that the fault which broke her engagement to Harry Feversham had been most bravely atoned, there could be no doubt as to the course which he would insist upon pursuing. He would strip himself of her, the one thing left to him, and that she was stubbornly determined he should not do. She was bound to him in honour, and it would be a poor way of manifesting her joy that Harry Feversham had redeemed his honour if she straightway sacrificed her own.

Captain Willoughby pursed up his lips and whistled.

"Engaged to Jack Durrance!" he exclaimed. "Then I seem to have wasted my time in bringing you that feather," and he pointed towards it. She was holding it in her open hand, and she drew her hand sharply away, as though she feared for a moment that he meant to rob her of it.

"I am most grateful for it," she returned.

"It's a bit of a muddle, isn't it?" Willoughby remarked. "It seems a little rough on Feversham perhaps. It's a little rough on Jack Durrance, too, when you come to think of it." Then he looked at Ethne. He noticed her careful handling of the feather; he remembered something of the glowing look with which she had listened to his story, something of the eager tones in which she had put her questions; and he added, "I shouldn't wonder if it was rather rough on you too, Miss Eustace."

Ethne did not answer him, and they walked together out of the enclosure towards the spot where Willoughby had moored his boat. She hurried him down the bank to the water's edge, intent that he should sail away unperceived.

But Ethne had counted without Mrs. Adair, who all that morning had seen much in Ethne's movements to interest her. From the drawing-room window she had watched Ethne and Durrance meet at the foot of the terrace-steps, she had seen them walk together towards the estuary, she had noticed Willoughby's boat as it ran aground in the wide gap between the trees, she had seen a man disembark, and Ethne go forward to meet him. Mrs. Adair was not the woman to leave her post of observation at such a moment, and from the cover of the curtains she continued to watch with all the curiosity of a woman in a village who draws down the blind, that un.o.bserved she may get a better peep at the stranger pa.s.sing down the street. Ethne and the man from the boat turned away and disappeared amongst the trees, leaving Durrance forgotten and alone. Mrs. Adair thought at once of that enclosure at the water's edge. The conversation lasted for some while, and since the couple did not promptly reappear, a question flashed into her mind. "Could the stranger be Harry Feversham?"

Ethne had no friends in this part of the world. The question pressed upon Mrs. Adair. She longed for an answer, and of course for that particular answer which would convict Ethne Eustace of duplicity. Her interest grew into an excitement when she saw Durrance, tired of waiting, follow upon Ethne's steps. But what came after was to interest her still more.

Durrance reappeared, to her surprise alone, and came straight to the house, up the terrace, into the drawing-room.

"Have you seen Ethne?" he asked.

"Is she not in the little garden by the water?" Mrs. Adair asked.

"No. I went into it and called to her. It was empty."

"Indeed?" said Mrs. Adair. "Then I don't know where she is. Are you going?"

"Yes, home."

Mrs. Adair made no effort to detain him at that moment.

"Perhaps you will come in and dine to-night. Eight o'clock."

"Thanks, very much. I shall be pleased," said Durrance, but he did not immediately go. He stood by the window idly swinging to and fro the ta.s.sel of the blind.

"I did not know until to-day that it was your plan that I should come home and Ethne stay with you until I found out whether a cure was likely or possible. It was very kind of you, Mrs. Adair, and I am grateful."

"It was a natural plan to propose as soon as I heard of your ill-luck."

"And when was that?" he asked unconcernedly. "The day after Calder's telegram reached her from Wadi Halfa, I suppose."

Mrs. Adair was not deceived by his att.i.tude of carelessness. She realised that his expression of grat.i.tude had deliberately led up to this question.

"Oh, so you knew of that telegram," she said. "I thought you did not."

For Ethne had asked her not to mention it on the very day when Durrance returned to England.

"Of course I knew of it," he returned, and without waiting any longer for an answer he went out on to the terrace.

Mrs. Adair dismissed for the moment the mystery of the telegram. She was occupied by her conjecture that in the little garden by the water's edge Durrance had stood and called aloud for Ethne, while within twelve yards of him, perhaps actually within his reach, she and some one else had kept very still and had given no answer. Her conjecture was soon proved true. She saw Ethne and her companion come out again on to the open lawn. Was it Feversham? She must have an answer to that question. She saw them descend the bank towards the boat, and, stepping from her window, ran.

Thus it happened that as Willoughby rose from loosening the painter, he saw Mrs. Adair's disappointed eyes gazing into his. Mrs. Adair called to Ethne, who stood by Captain Willoughby, and came down the bank to them.

"I noticed you cross the lawn from the drawing-room window," she said.

"Yes?" answered Ethne, and she said no more. Mrs. Adair, however, did not move away, and an awkward pause followed. Ethne was forced to give in.

"I was talking to Captain Willoughby," and she turned to him. "You do not know Mrs. Adair, I think?"

"No," he replied, as he raised his hat. "But I know Mrs. Adair very well by name. I know friends of yours, Mrs. Adair--Durrance, for instance; and of course I knew--"

A glance from Ethne brought him abruptly to a stop. He began vigorously to push the nose of his boat from the sand.

"Of course, what?" asked Mrs. Adair, with a smile.

"Of course I knew of you, Mrs. Adair."
