But as soon as the inquiry was abandoned he became gradually nervous, more excitable than he had been before, although he mastered his irritability. Sudden noises made him start with fear; he shuddered at the slightest thing and trembled sometimes from head to foot when a fly alighted on his forehead. Then he was seized with an imperious desire for motion, which impelled him to take long walks and to remain up whole nights pacing up and down his room. It was not that he was goaded by remorse. His brutal nature did not lend itself to any shade of sentiment or of moral terror. A man of energy and even of violence, born to make war, to ravage conquered countries and to massacre the vanquished, full of the savage instincts of the hunter and the fighter, he scarcely took count of human life. Though he respected the Church outwardly, from policy, he believed neither in God nor the devil, expecting neither chastisement nor recompense for his acts in another life. His sole belief was a vague philosophy drawn from all the ideas of the encyclopedists of the last century, and he regarded religion as a moral sanction of the law, the one and the other having been invented by men to regulate social relations. To kill any one in a duel, or in war, or in a quarrel, or by accident, or for the sake of revenge, or even through bravado would have seemed to him an amusing and clever thing and would not have left more impression on his mind than a shot fired at a hare; but he had experienced a profound emotion at the murder of this child. He had, in the first place, perpetrated it in the heat of an irresistible gust of passion, in a sort of tempest of the senses that had overpowered his reason. And he had cherished in his heart, in his flesh, on his lips, even to the very tips of his murderous fingers a kind of bestial love, as well as a feeling of terrified horror, toward this little girl surprised by him and basely killed. Every moment his thoughts returned to that horrible scene, and, though he endeavored to drive this picture from his mind, though he put it aside with terror, with disgust, he felt it surging through his soul, moving about in him, waiting incessantly for the moment to reappear. Then, as evening approached, he was afraid of the shadow falling around him. He did not yet know why the darkness seemed frightful to him, but he instinctively feared it, he felt that it was peopled with terrors. The bright daylight did not lend itself to fears. Things and beings were visible then, and only natural things and beings could exhibit themselves in the light of day. But the night, the impenetrable night, thicker than walls and empty; the infinite night, so black, so vast, in which one might brush against frightful things; the night, when one feels that a mysterious terror is wandering, prowling about, appeared to him to conceal an unknown threatening danger, close beside him. What was it?
