But Madame Fosco seemed resolved not to part with me, and to my unspeakable amazement, resolved also to talk. Hitherto the most silent of women, she now persecuted me with fluent conventionalities on the subject of married life, on the subject of Sir Percival and Laura, on the subject of her own happiness, on the subject of the late Mr Fairlie's conduct to her in the matter of her legacy, and on half a dozen other subjects besides, until she had detained me walking round and round the fishpond for more than half an hour, and had quite wearied me out. Whether she discovered this or not, I cannot say, but she stopped as abruptly as she had begun -- looked towards the house door, resumed her icy manner in a moment, and dropped my arm of her own accord before I could think of an excuse for accomplishing my own release from her.

As I pushed open the door and entered the hall, I found myself suddenly face to face with the Count again. He was just putting a letter into the post-bag.

After he had dropped it in and had closed the bag, he asked where I had left Madame Fosco. I told him, and he went out at the hall door immediately to join his wife. His manner when he spoke to me was so unusually quiet and subdued that I turned and looked after him, wondering if he were ill or out of spirits.

Why my next proceeding was to go straight up to the post-bag and take out my own letter and look at it again, with a vague distrust on me, and why the looking at it for the second time instantly suggested the idea to my mind of sealing the envelope for its greater security -- are mysteries which are either too deep or too shallow for me to fathom. Women, as everybody knows, constantly act on impulses which they cannot explain even to themselves, and I can only suppose that one of those impulses was the hidden cause of my unaccountable conduct on this occasion.

Whatever influence animated me, I found cause to congratulate myself on having obeyed it as soon as I prepared to seal the letter in my own room. I had originally closed the envelope in the usual way by moistening the adhesive point and pressing it on the paper beneath, and when I now tried it with my finger, after a lapse of full three-quarters of an hour, the envelope opened on the instant, without sticking or tearing. Perhaps I had fastened it insufficiently? Perhaps there might have been some defect in the adhesive gum?

Or, perhaps -- No! it is quite revolting enough to feel that third conjecture stirring in my mind. I would rather not see it confronting me in plain black and white.

I almost dread tomorrow -- so much depends on my discretion and self-control. There are two precautions, at all events, which I am sure not to forget. I must be careful to keep up friendly appearances with the Count, and I must be well on my guard when the messenger from the office comes here with the answer to my letter.
