He considered with himself for a moment, and went on - with a horrid clearness that obliged you to understand him; with an abominable justice that favoured nobody.

"My first information relating to the loss of the Moonstone," said the Sergeant, "came to me from Superintendent Seegrave. He proved to my complete satisfaction that he was perfectly incapable of managing the case. The one thing he said which struck me as worth listening to, was this - that Miss Verinder had declined to be questioned by him, and had spoken to him with a perfectly incomprehensible rudeness and contempt. I thought this curious - but I attributed it mainly to some clumsiness on the Superintendent's part which might have offended the young lady. After that, I put it by in my mind, and applied myself, single-handed, to the case. It ended, as you are aware, in the discovery of the smear on the door, and in Mr. Franklin Blake's evidence satisfying me, that this same smear, and the loss of the Diamond, were pieces of the same puzzle. So far, if I suspected anything, I suspected that the Moonstone had been stolen, and that one of the servants might prove to be the thief. Very good. In this state of things, what happens? Miss Verinder suddenly comes out of her room, and speaks to me. I observe three suspicious appearances in that young lady. She is still violently agitated, though more than four-and-twenty hours have passed since the Diamond was lost. She treats me as she has already treated Superintendent Seegrave. And she is mortally offended with Mr. Franklin Blake. Very good again. Here (I say to myself) is a young lady who has lost a valuable jewel - a young lady, also, as my own eyes and ears inform me, who is of an impetuous temperament. Under these circumstances, and with that character, what does she do? She betrays an incomprehensible resentment against Mr. Blake, Mr. Superintendent, and myself - otherwise, the very three people who have all, in their different ways, been trying to help her to recover her lost jewel. Having brought my inquiry to that point - THEN, my lady, and not till then, I begin to look back into my own mind for my own experience. My own experience explains Miss Verinder's otherwise incomprehensible conduct. It associates her with those other young ladies that I know of. It tells me she has debts she daren't acknowledge, that must be paid. And it sets me asking myself, whether the loss of the Diamond may not mean - that the Diamond must be secretly pledged to pay them. That is the conclusion which my experience draws from plain facts. What does your ladyship's experience say against it?"

"What I have said already," answered my mistress. "The circumstances have misled you."

I said nothing on my side. ROBINSON CRUSOE - God knows how - had got into my muddled old head. If Sergeant Cuff had found himself, at that moment, transported to a desert island, without a man Friday to keep him company, or a ship to take him off - he would have found himself exactly where I wished him to be! (Nota bene: - I am an average good Christian, when you don't push my Christianity too far. And all the rest of you - which is a great comfort - are, in this respect, much the same as I am.)

Sergeant Cuff went on:

"Right or wrong, my lady," he said, "having drawn my conclusion, the next thing to do was to put it to the test. I suggested to your ladyship the examination of all the wardrobes in the house. It was a means of finding the article of dress which had, in all probability, made the smear; and it was a means of putting my conclusion to the test. How did it turn out? Your ladyship consented; Mr. Blake consented; Mr. Ablewhite consented. Miss Verinder alone stopped the whole proceeding by refusing point-blank. That result satisfied me that my view was the right one. If your ladyship and Mr. Betteredge persist in not agreeing with me, you must be blind to what happened before you this very day. In your hearing, I told the young lady that her leaving the house (as things were then) would put an obstacle in the way of my recovering her jewel. You saw yourselves that she drove off in the face of that statement. You saw yourself that, so far from forgiving Mr. Blake for having done more than all the rest of you to put the clue into my hands, she publicly insulted Mr. Blake, on the steps of her mother's house. What do these things mean? If Miss Verinder is not privy to the suppression of the Diamond, what do these things mean?"

This time he looked my way. It was downright frightful to hear him piling up proof after proof against Miss Rachel, and to know, while one was longing to defend her, that there was no disputing the truth of what he said. I am (thank God!) constitutionally superior to reason. This enabled me to hold firm to my lady's view, which was my view also. This roused my spirit, and made me put a bold face on it before Sergeant Cuff. Profit, good friends, I beseech you, by my example. It will save you from many troubles of the vexing sort. Cultivate a superiority to reason, and see how you pare the claws of all the sensible people when they try to scratch you for your own good!

Finding that I made no remark, and that my mistress made no remark, Sergeant Cuff proceeded. Lord! how it did enrage me to notice that he was not in the least put out by our silence!

"There is the case, my lady, as it stands against Miss Verinder alone," he said. "The next thing is to put the case as it stands against Miss Verinder and the deceased Rosanna Spearman taken together. We will go back for a moment, if you please, to your daughter's refusal to let her wardrobe be examined. My mind being made up, after that circumstance, I had two questions to consider next. First, as to the right method of conducting my inquiry. Second, as to whether Miss Verinder had an accomplice among the female servants in the house. After carefully thinking it over, I determined to conduct the inquiry in, what we should call at our office, a highly irregular manner. For this reason: I had a family scandal to deal with, which 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 honour of the family at heart - would be safer to take as an assistant than any other person whom I could lay my hand on. I should have tried Mr. Blake as well - but for one obstacle in the way. HE saw the drift of my proceedings at a very early date; and, with his interest in Miss Verinder, any mutual understanding was impossible between him and me. I trouble your ladyship with these particulars to show you that I have kept the family secret within the family circle. I am the only outsider who knows it - and my professional existence depends on holding my tongue."
