She went early to the tower, almost afraid that he might have gone in the night. He was there, and Martin left them much together that day. In the afternoon they sat side by side on one of the broken pieces of masonry in the ruins, while Martin lounged by the door opening on to the terrace; and there was little of Crosby's life that Barbara had not been told before the dusk came. She did not question that he had told her the truth. And much about herself Barbara told him, but not yet of the evil which hung over Aylingford. She could not tell him that yet, and there was time enough, for she had advised that he should remain at the Abbey for a little while.

"I believe your enemies are private ones, and would only use this rebellion against you as a means to an end," she said. "When it is known that you took no part with Monmouth you will be free to deal with your enemies."

"You are not angry that I came, then?"

"No; and, besides, you may perchance do me a great service."

"How? Only tell me how," he whispered, and there was a new note in his voice which sent a thrill into her very soul and yet made her shrink from him a little.

"To-morrow—perhaps to-morrow I will tell you."

So the clouds of doubt were driven away, and yet they returned again as she sat in her room that evening, for she would not go again to the tower until to-morrow. Someone might have seen her go in that direction and wondered why she had spent so many hours in the ruins. She was angry with herself for allowing such doubts to enter her mind, but, try as she would, she could not force them out.

There came a knock upon her door presently, and a servant entered to request that she would go to Sir John.

"He is in his own room," said the servant, "and bid me say that he was waiting for you."

It was so unusual for her uncle to send for her that Barbara wondered what had happened to make her immediate presence necessary. Had Sir John found out that there was a visitor in the tower, and wished to question her? As she went she endeavoured to make up her mind what she should say if Gilbert Crosby's presence at Aylingford were the reason she was sent for.
