I pulled the door to again the moment his back was turned, and sat down for a while to compose myself.
He had been watching me at the book-case! The man who was in my husband's confidence, the man who knew where the clew was to be found, had been watching me at the book-case! There was no doubt of it now. Major Fitz-David had shown me the hiding-place of the secret in spite of himself!
I looked with indifference at the other pieces of furniture, ranged against the fourth wall, which I had not examined yet. I surveyed, without the slightest feeling of curiosity, all the little elegant trifles scattered on the tables and on the chimney-piece, each one of which might have been an object of suspicion to me under other circumstances. Even the water-color drawings failed to interest me in my present frame of mind. I observed languidly that they were most of them portraits of ladies--fair idols, no doubt, of the Major's facile adoration--and I cared to notice no more. My business in that room (I was certain of it now!) began and ended with the book-case. I left my seat to fetch the library ladder, determining to begin the work of investigation on the top shelves.
On my way to the ladder I passed one of the tables, and saw the keys lying on it which Major Fitz-David had left at my disposal.
The smaller of the two keys instantly reminded me of the cupboards under the bookcase. I had strangely overlooked these. A vague distrust of the locked doors a vague doubt of what they might be hiding from me, stole into my mind. I left the ladder in its place against the wall, and set myself to examine the contents of the cupboards first.
The cupboards were three in number. As I opened the first of them the singing upstairs ceased. For a moment there was something almost oppressive in the sudden change from noise to silence. I suppose my nerves must have been overwrought. The next sound in the house--nothing more remarkable than the creaking of a man's boots descending the stairs--made me shudder all over. The man was no doubt the singing-master, going away after giving his lesson. I heard the house door close on him, and started at the familiar sound as if it were something terrible which I had never heard before. Then there was silence again. I roused myself as well as I could, and began my examination of the first cupboard.
It was divided into two compartments.
The top compartment contained nothing but boxes of cigars, ranged in rows, one on another. The under compartment was devoted to a collection of shells. They were all huddled together anyhow, the Major evidently setting a far higher value on his cigars than on his shells. I searched this lower compartment carefully for any object interesting to me which might be hidden in it. Nothing was to be found in any part of it besides the shells.
