"I was afraid to put it off till next day (the Friday); being in doubt lest some accident might happen in the interval. I determined to make the new nightgown on that same day (the Thursday), while I could count, if I played my cards properly, on having my time to myself. The first thing to do (after locking up your nightgown in my drawer) was to go back to your bed-room - not so much to put it to rights (Penelope would have done that for me, if I had asked her) as to find out whether you had smeared off any of the paint-stain from your nightgown, on the bed, or on any piece of furniture in the room.

"I examined everything narrowly, and at last, I found a few streaks of the paint on the inside of your dressing-gown - not the linen dressing-gown you usually wore in that summer season, but a flannel dressing-gown which you had with you also. I suppose you felt chilly after walking to and fro in nothing but your nightdress, and put on the warmest thing you could find. At any rate, there were the stains, just visible, on the inside of the dressing-gown. I easily got rid of these by scraping away the stuff of the flannel. This done, the only proof left against you was the proof locked up in my drawer.

"I had just finished your room when I was sent for to be questioned by Mr. Seegrave, along with the rest of the servants. Next came the examination of all our boxes. And then followed the most extraordinary event of the day - to ME - since I had found the paint on your nightgown. This event came out of the second questioning of Penelope Betteredge by Superintendent Seegrave.

"Penelope returned to us quite beside herself with rage at the manner in which Mr. Seegrave had treated her. He had hinted, beyond the possibility of mistaking him, that he suspected her of being the thief. We were all equally astonished at hearing this, and we all asked, Why?

"'Because the Diamond was in Miss Rachel's sitting-room," Penelope answered. "And because I was the last person in the sitting-room at night!"

"Almost before the words had left her lips, I remembered that another person had been in the sitting-room later than Penelope. That person was yourself. My head whirled round, and my thoughts were in dreadful confusion. In the midst of it all, something in my mind whispered to me that the smear on your nightgown might have a meaning entirely different to the meaning which I had given to it up to that time. 'If the last person who was in the room is the person to be suspected,' I thought to myself, 'the thief is not Penelope, but Mr. Franklin Blake!'

"In the case of any other gentleman, I believe I should have been ashamed of suspecting him of theft, almost as soon as the suspicion had passed through my mind.

"But the bare thought that YOU had let yourself down to my level, and that I, in possessing myself of your nightgown, had also possessed myself of the means of shielding you from being discovered, and disgraced for life - I say, sir, the bare thought of this seemed to open such a chance before me of winning your good will, that I passed blindfold, as one may say, from suspecting to believing. I made up my mind, on the spot, that you had shown yourself the busiest of anybody in fetching the police, as a blind to deceive us all; and that the hand which had taken Miss Rachel's jewel could by no possibility be any other hand than yours.

"The excitement of this new discovery of mine must, I think, have turned my head for a while. I felt such a devouring eagerness to see you - to try you with a word or two about the Diamond, and to MAKE you look at me, and speak to me, in that way - that I put my hair tidy, and made myself as nice as I could, and went to you boldly in the library where I knew you were writing.

"You had left one of your rings up-stairs, which made as good an excuse for my intrusion as I could have desired. But, oh, sir! if you have ever loved, you will understand how it was that all my courage cooled, when I walked into the room, and found myself in your presence. And then, you looked up at me so coldly, and you thanked me for finding your ring in such an indifferent manner, that my knees trembled under me, and I felt as if I should drop on the floor at your feet. When you had thanked me, you looked back, if you remember, at your writing. I was so mortified at being treated in this way, that I plucked up spirit enough to speak. I said, 'This is a strange thing about the Diamond, sir.' And you looked up again, and said, 'Yes, it is!' You spoke civilly (I can't deny that); but still you kept a distance - a cruel distance between us. Believing, as I did, that you had got the lost Diamond hidden about you, while you were speaking, your coolness so provoked me that I got bold enough, in the heat of the moment, to give you a hint. I said, 'They will never find the Diamond, sir, will they? No! nor the person who took it - I'll answer for that.' I nodded, and smiled at you, as much as to say, 'I know!' THIS time, you looked up at me with something like interest in your eyes; and I felt that a few more words on your side and mine might bring out the truth. Just at that moment, Mr. Betteredge spoilt it all by coming to the door. I knew his footstep, and I also knew that it was against his rules for me to be in the library at that time of day - let alone being there along with you. I had only just time to get out of my own accord, before he could come in and tell me to go. I was angry and disappointed; but I was not entirely without hope for all that. The ice, you see, was broken between us - and I thought I would take care, on the next occasion, that Mr. Betteredge was out of the way.

"When I got back to the servants' hall, the bell was going for our dinner. Afternoon already! and the materials for making the new nightgown were still to be got! There was but one chance of getting them. I shammed ill at dinner; and so secured the whole of the interval from then till tea-time to my own use.
