She stopped and said to herself, several times over, in a low voice, "Help!... Help!..." as though the word awakened an idea, a memory within her, and as though the hope of assistance no longer seemed to her impossible. For some minutes she remained absorbed in deep meditation, broken by fears and starts. Then, with an almost mechanical series of movements, she put out her arm to a little set of shelves hanging over the writing-desk, took down four books, one after the other, turned the pages with a distraught air, replaced them and ended by finding, between the pages of the fifth, a visiting-card on which her eyes spelt the name: HORACE VELMONT, followed by an address written in pencil: CERCLE DE LA RUE ROYALE. And her memory conjured up the strange thing which that man had said to her, a few years before, in that same house, on a day when she was at home to her friends: "If ever a danger threatens you, if you need help, do not hesitate; post this card, which you see me put into this book; and, whatever the hour, whatever the obstacles, I will come." With what a curious air he had spoken these words and how well he had conveyed the impression of certainty, of strength, of unlimited power, of indomitable daring! Abruptly, unconsciously, acting under the impulse of an irresistible determination, the consequences of which she refused to anticipate, Yvonne, with the same automatic gestures, took a pneumatic-delivery envelope, slipped in the card, sealed it, directed it to "Horace Velmont, Cercle de la Rue Royale" and went to the open window. The policeman was walking up and down outside. She flung out the envelope, trusting to fate. Perhaps it would be picked up, treated as a lost letter and posted. She had hardly completed this act when she realized its absurdity. It was mad to suppose that the message would reach the address and madder still to hope that the man to whom she was sending could come to her assistance, "whatever the hour, whatever the obstacles." A reaction followed which was all the greater inasmuch as the effort had been swift and violent. Yvonne staggered, leant against a chair and, losing all energy, let herself fall. The hours passed by, the dreary hours of winter evenings when nothing but the sound of carriages interrupts the silence of the street. The clock struck, pitilessly. In the half-sleep that numbed her limbs, Yvonne counted the strokes. She also heard certain noises, on different floors of the house, which told her that her husband had dined, that he was going up to his room, that he was going down again to his study. But all this seemed very shadowy to her; and her torpor was such that she did not even think of lying down on the sofa, in case he should come in....
