"Unless, indeed, that----" This letter was written on the first Sunday in June, 1864; and on the following Thursday, four days later, he who had written it, and had suffered all it revealed, went out to the appointment at which he met with his mysterious death, that death by which his wife was set free to marry his felon friend. What was the idea, as dreadful, as infamous as the idea of which my father accused himself in his terrible last letter, that flashed across me now? I placed the packet of papers upon the mantelpiece, and pressed my two hands to my head, as though to still the tempest of cruel fancies which made it throb with fever. Ah, the hideous, nameless thing! My mind got a glimpse of it only to reject it. But, had not my aunt also been assailed by the same monstrous suspicion? A number of small facts rose up in my memory, and convinced me that my father's faithful sister had been a prey to the same idea which had just laid hold of me so strongly. How many strange things I now understood, all in a moment! On that day when she told me of my mother's second marriage, and I spontaneously uttered the accursed name of Termonde, why had she asked me, in a trembling voice: "What do you know?" What was it she feared that I had guessed? What dreadful information did she expect to receive from my childish observation of things? Afterwards, and when she implored me to abandon the task of avenging our beloved dead, when she quoted to me the sacred words, "Vengeance is mine, saith the Lord," who were the guilty ones whom she foresaw I must meet on my path? When she entreated me to bear with my stepfather, even to conciliate him, not to make an enemy of him, had her advice any object except the greater ease of my daily life, or did she think danger might come to me from that quarter? When she became more afraid for me, owing to the weakening of her brain by illness, and again and again enjoined upon me to beware of going out alone in the evening, was the vision of terror that came to her that of a hand which would fain strike me in the dark--the same hand that had struck my father? When she summoned up all her strength in her last moments, that she might destroy this correspondence, what was the clue which she supposed the letters would furnish? A terrific light shone upon me; what my aunt had perceived beyond the plain purport of the letters, I too perceived. Ah! I dared to entertain this idea, yet now I am ashamed to write it down. But could I have escaped from the hard logic of the situation? If my aunt had handed over those letters to the Judge of Instruction in the matter, would he not have arrived at the same conclusion that I drew from them? No, I could not. A man who has no known enemies is assassinated; it is alleged that robbery is not the motive of the murder; his wife has a lover, and shortly after the death of her husband she marries that lover. "But it is they--it is they who
