I slept not one wink that night. I can compare the state of my mind to nothing but a still, deep piece of water, suddenly stirred by a strong wind. Thought was a confused mass of waves, flowing one into the other, and hurrying away into some new form, ere they could be measured or defined. Toward morning, however, one of the memories the most prominent became that of the surprise which had been shown by the Count and Countess de Salins at my having seen and conversed with the Marquis de Carcassonne. I dwelt upon it. I pondered. I scrutinized it. “The murderer of my father!” I thought; “how did he murder him? Was it in a duel: by an act which good Father Bonneville, with his strong principles, might look upon as murder?” No—there must have been something more. What the count had said in regard to the other’s guilt showed that it was by no common occurrence my father fell. There must have been something more; and what that was I determined to ascertain. Not that I thought of taking vengeance on the pitiful dying worm I had seen—he was not worthy of it. The extinction of his few short hours of life would offer but poor satisfaction. “Better leave him in the hand of God,” I thought, “who knows all and sees all, and is just as well as merciful.” Nevertheless, I was determined to know how my father fell, and that without any long delay. I knew that where there is a strong will, means are rarely wanting to accomplish even the most improbable ends: but, after long meditation, I saw but one way of arriving at my object: “I will go to the old man,” I thought, “and drive him to tell me all. I will strengthen my mind, and harden my heart, and compel him to divulge the dark secret within his breast.” Such was my first resolution, and it was that to which I recurred; but, in the mean time, another plan suggested itself, which I tried, but which failed. I thought that, very probably, the Count de Salins himself would give me information; and as the mind—especially of youth—is always fond of accomplishing more than one object at a time, I resolved to go down the very next day, and pass an hour or two with Mariette, at the same time I sought the information I required. There was one thing, however, which embarrassed me a good deal—not that it presented itself to my mind in any definite shape; but it had crossed my thoughts like a vague, unpleasant shadow more than once during the night. I do not know that I can very well explain myself distinctly—that I can make any one else, even those for whom these pages are written, and who understand me best, comprehend fully the state of my mind at that moment. I should perhaps have said, in common parlance, the state of my heart, but mind had something to do with it likewise. Let me try, however.
