"Yes, father, I agree with you. There would be nothing treacherous in that. I have simply to try to get her to make a confession of anything she may know in the matter. I quite agree with you in all you have said about the man, but I do not see how Ruth Powlett can know anything for certain, whatever she may suspect; for if she was, as you say, dangerously ill for a long time after the murder, she cannot very well have seen the man, who would be sure to have quitted the country at once." "I am afraid that that is so, Mary. Still, we must hope for the best, and if she cannot give us absolute evidence herself, what she says may at least put us in the right track for obtaining it. Even if no legal evidence can be obtained, we might get enough clues, with what we have already, to convince the world that whereas hitherto there seemed no alternative open as to Mervyn's guilt, there was in fact another against whom there is at any rate a certain amount of proof, and whose character is as bad as that of Captain Mervyn is good. This would in itself be a great step. Mervyn has been acquitted, but as no one else is shown to have been connected with it in any way, people are compelled, in spite of his previous character, in spite of his acquittal, in spite in fact even of probability, to consider him guilty. Once shown that there is at least reasonable ground for suspicion against another, and the opinion, at any rate of all who know Mervyn, would at once veer round." "Very well, father; now you have done your part of the work by finding out the clue, I will do mine by following it up. Fortunately, Ruth Powlett is a very superior sort of girl to any one in the village, and I can make friends with her heartily and without pretence. I should have found it very hard if she had been a rough sort of girl, but she expresses herself just as well as I do, and seems very gentle and nice. One can see that even that sharp-voiced stepmother of hers is very fond of her, and she is the apple of the miller's eye. But you must not be impatient, father; two girls can't become great friends all at once." "I think, on the whole, Miss Armstrong," her father said, "you are quite as likely to become impatient as I am, seeing that it is your business much more than mine." "Well, you may be sure I shall not lose more time than I can help, father." Mary Armstrong laughed. "You don't know how joyous I feel to-night, I have always been hopeful, but it did seem so vague before. Now that we have got what we think to be a clue, and can set to work at once, I feel ever so much nearer to seeing Ronald again." The consequence of this conversation was that Mary Armstrong went very frequently down to the mill, and induced Ruth Powlett, sometimes, to come up and sit with her.
