So terrible a situation ought to have troubled the mind of the most hardened criminal. A man familiar with murder and accustomed to shed blood might have felt his heart sink, and, in the absence of pity, might have experienced disgust at the sight of this prolonged and useless torture; but Derues, calm and easy, as if unconscious of evil, sat coolly beside the bed, as any doctor might have done. From time to time he felt the slackening pulse, and looked at the glassy and sightless eyes which turned in their orbits, and he saw without terror the approach of night, which rendered this awful ‘tete-a-tete’ even more horrible. The most profound silence reigned in the house, the street was deserted, and the only sound heard was caused by an icy rain mixed with snow driven against the glass, and occasionally the howl of the wind, which penetrated the chimney and scattered the ashes. A single candle placed behind the curtains lighted this dismal scene, and the irregular flicker of its flame cast weird reflections and dancing shadows an the walls of the alcove. There came a lull in the wind, the rain ceased, and during this instant of calm someone knocked, at first gently, and then sharply, at the outer door. Derues dropped the dying woman’s hand and bent forward to listen. The knock was repeated, and he grew pale. He threw the sheet, as if it were a shroud, over his victim’s head drew the curtains of the alcove, and went to the door. “Who is there?” he inquired. “Open, Monsieur Derues,” said a voice which he recognised as that of a woman of Chartres whose affairs he managed, and who had entrusted him with sundry deeds in order that he might receive the money due to her. This woman had begun to entertain doubts as to Derues’ honesty, and as she was leaving Paris the next day, had resolved to get the papers out of his hands. “Open the door,” she repeated. “Don’t you know my voice?” “I am sorry I cannot let you in. My servant is out: she has taken the key and locked the door outside.” “You must let me in,” the woman continued; “it is absolutely necessary I should speak to you.” “Come to-morrow.” “I leave Paris to-morrow, and I must have those papers to-night.” He again refused, but she spoke firmly and decidedly. “I must come in. The porter said you were all out, but, from the rue des Menetriers I could see the light in your room. My brother is with me, and I left him below. I shall call him if you don’t open the door.” “Come in, then,” said Derues; “your papers are in the sitting-room. Wait here, and I will fetch them.” The woman looked at him and took his hand. “Heavens! how pale you are! What is the matter?” “Nothing is the matter: will you wait here? “But she would not release his arm, and followed him into the sitting-room, where Derues began to seek hurriedly among the various papers which covered a table. “Here they are,” he said; “now you can go.”
