What was it?
He knew it ere long. As he sat in his armchair, rather late one evening when he could not sleep, he thought he saw the curtain of his window move. He waited, in an uneasy state of mind, with beating heart. The drapery did not stir; then, all of a sudden it moved once more. He did not venture to rise up; he no longer ventured to breathe, and yet he was brave. He had often fought, and he would have liked to catch thieves in his house.
Was it true that this curtain did move? he asked himself, fearing that his eyes had deceived him. It was, moreover, such a slight thing, a gentle flutter of lace, a kind of trembling in its folds, less than an undulation such as is caused by the wind.
Renardet sat still, with staring eyes, and outstretched neck; and he sprang to his feet abruptly ashamed of his fear, took four steps, seized the drapery with both hands, and pulled it wide apart. At first, he saw nothing but darkened glass, resembling plates of glittering ink. The night, the vast, impenetrable sketched behind as far as the invisible horizon. He remained standing in front of this illimitable shadow, and suddenly he perceived a light, a moving light, which seemed some distance away.
Then he put his face close to the window-pane, thinking that a person looking for crayfish might be poaching in the Brindelle, for it was past midnight, and this light rose up at the edge of the stream, under the trees. As he was not yet able to see clearly, Renardet placed his hands over his eyes; and suddenly this light became an illumination, and he beheld little Louise Roqué naked and bleeding on the moss. He recoiled frozen with horror, sank into his chair, and fell backward. He remained there some minutes, his soul in distress, then he sat up and began to reflect. He had had a hallucination—that was all; a hallucination due to the fact that a marauder of the night was walking with a lantern in his hand near the water's edge. What was there astonishing, besides, in the circumstance that the recollection of his crime should sometimes bring before him the vision of the dead girl?
He rose up, swallowed a glass of wine and sat down again.
He thought.
"What am I to do if this come back?"
And it did come back; he felt it; he was sure of it. Already his glance was drawn towards the window; it called him; it attracted him. In order to avoid looking at it, he turned aside his chair. Then he took a book and tried to read; but it seemed to him that he presently heard something stirring behind him, and he swung round his armchair on one foot.
The curtain still moved—unquestionably, it did move this time; he could no longer have any doubt about it.
