"Chase?" Pamela repeated; and she retained the name in her memory.
"But he doesn't know Millie," said Stretton, "and you do. And so what you said troubles me very much. If I go away remembering your words and not understanding them, I shall go away uneasy. I shall remain uneasy."
"I am sorry," Pamela replied. "I broke a rule of mine in saying what I did, a rule not to interfere. And I see now that I did very wrong in breaking it. I will not break it again. You must forget my words."
There was a quiet decision in her manner which warned Tony that no persuasions would induce her to explain. He gave up his attempt and turned to another subject.
"I have something else to ask--not a question this time, but a favour. You could be a very staunch friend, Miss Mardale, if you chose. Millie will be lonely after I have gone. You were a great friend of hers once--be a friend of hers again."
Pamela hesitated. The promise which he sought on the face of it no doubt looked easy of fulfilment. But Tony Stretton had been right in one conjecture. She had spoken the words which troubled him from a definite reason, and that reason assured her now that this promise might lay upon her a burden, and a burden of a heavy kind. And she shrank from all burdens. On the other hand, there was no doubt that she had caused Tony much uneasiness. He would go away, on a task which, as she saw very clearly, would be more arduous by far than even he suspected--he would go away troubled and perplexed. That could not be helped. But she might lighten the trouble, and make the perplexity less insistent, if she granted the favour which he sought. It seemed churlish to refuse.
"Very well," she said reluctantly. "I promise."
Already Tony's face showed his relief. She had given her promise reluctantly, but she would keep it now. Of that he felt assured, and, bidding her good-bye, he turned his horse and cantered back.
Pamela rode homewards more slowly. She had proposed to keep clear of entanglements and responsibilities, and, behold! the meshes were about her. She had undertaken a trust. In spite of herself she had ceased to be the looker-on.
