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 unobserved she may get a better peep at the stranger passing 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 tassel of the blind.
