"Just so, Harry.  Then I have a secret which I want you to keep for me-- or, perhaps, I had better say that I have something which I should like to tell you, because I believe you may be able to help me in an important matter.  And instead of binding you to keep my secret, I shall just leave it to your own good sense to say nothing about the matter till the right time comes; and I am sure, when you know all, you will have no wish to make my business a subject of conversation in the family, nor of idle gossip out of it."
