it was my business to keep within the family limits. The less noise made, and the fewer strangers employed to help me, the better. As to the usual course of taking people in custody on suspicion, going before the magistrate, and all the rest of it—nothing of the sort was to be thought of, when your ladyship's daughter was (as I believed) at the bottom of the whole business. In this case, I felt that a person of Mr. Betteredge's character and position in the house—knowing the servants as he did, and having the honor of the family at heart—would be safer to take as an assistant than any other person whom I could lay my hand on.

My lady informed him that he might continue his statement. "I understand," she said, "that you have honestly done your best, in what you believe to be my interest. I am ready to hear what you have to say next."
"What I have to say next," answered Sergeant Cuff, "relates to Rosanna Spearman. I recognized the young woman, as your ladyship may remember, when she brought the washing-book into this room. Up to that time I was inclined to doubt whether Miss Verinder had trusted her secret to any one. When I saw Rosanna, I altered my mind. I suspected her at once of being privy to the suppression of the Diamond. The poor creature has met her death by a dreadful end, and I don't want your ladyship to think, now
