At length, in reading some French Memoirs, I found an account of a nearly fatal illness that occurred to Madame Pilau, through the agency of a candle accidentally poisoned. The idea struck my fancy at once. I knew my victim's habit of reading in bed. I knew, too, that his apartment was narrow and ill-ventilated. But I need not vex you with impertinent details. I need not describe the easy artifices by which I substituted, in his bed-room candle-stand, a wax-light of my own making for the one which I there found. The next morning he was discovered dead in his bed, and the Coroner's verdict was—"Death by the visitation of God."

Having inherited his estate, all went well with me for years. The idea of detection never once entered my brain. Of the remains of the fatal taper I had myself carefully disposed. I had left no shadow of a clew by which it would be possible to convict, or even to suspect me of the crime. It is inconceivable how rich a sentiment of satisfaction arose in my bosom as I reflected upon my absolute security. For a very long period of time I was accustomed to revel in this sentiment. It afforded me more real delight than all the mere worldly advantages accruing from my sin. But there arrived at length an epoch, from which the pleasurable feeling grew, by scarcely perceptible gradations, into a haunting and harassing thought. It harassed because it haunted. I could scarcely get rid of it for an instant. It is quite a common thing to be thus annoyed with the ringing in our ears, or rather in our memories, of the burthen of some ordinary song, or some unimpressive snatches from an opera. Nor will we be the less tormented if the song in itself be good, or the opera air meritorious. In this manner, at last, I would perpetually catch myself pondering upon my security, and repeating, in a low undertone, the phrase, "I am safe."

One day, whilst sauntering along the streets, I arrested myself in the act of murmuring, half aloud, these customary syllables. In a fit of petulance, I remodelled them thus; "I am safe—I am safe—yes—if I be not fool enough to make open confession!"
