At this moment, therefore, her children came between Pepita and her true life, just as Science had come between herself and Balthazar. And thus, when she reached home after vespers, and threw herself into the deep armchair before the window of the parlor, she sent away her children, directing them to keep perfectly quiet, and despatched a message to her husband, through Lemulquinier, saying that she wished to see him. But although the old valet did his best to make his master leave the laboratory, Balthazar scarcely heeded him. Madame Claes thus gained time for reflection. She sat thinking, paying no attention to the hour nor the light. The thought of owing thirty thousand francs that could not be paid renewed her past anguish and joined it to that of the present and the future. This influx of painful interests, ideas, and feelings overcame her, and she wept. As Balthazar entered at last through the panelled door, the expression of his face seemed to her more dreadful, more absorbed, more distracted than she had yet seen it. When he made her no answer she was magnetized for a moment by the fixity of that blank look emptied of all expression, by the consuming ideas that issued as if distilled from that bald brow. Under the shock of this impression she wished to die. But when she heard the callous voice, uttering a scientific wish at the moment when her heart was breaking, her courage came back to her; she resolved to struggle with that awful power which had torn a lover from her arms, a father from her children, a fortune from their home, happiness from all. And yet she could not repress a trepidation which made her quiver; in all her life no such solemn scene as this had taken place. This dreadful moment--did it not virtually contain her future, and gather within it all the past? Weak and timid persons, or those whose excessive sensibility magnifies the smallest difficulties of life, men who tremble involuntarily before the masters of their fate, can now, one and all, conceive the rush of thoughts that crowded into the brain of this woman, and the feelings under the weight of which her heart was crushed as her husband slowly crossed the room towards the garden-door. Most women know that agony of inward deliberation in which Madame Claes was writhing. Even one whose heart has been tried by nothing worse than the declaration to a husband of some extravagance, or a debt to a dress-maker, will understand how its pulses swell and quicken when the matter is one of life itself.
