She drew her hand away abruptly, and sprang backward, like some proud, untamable animal, rearing; then she rushed quickly through the darkness toward the house. He heard the patter of her little boots on the stones of the yard, deadened afterward by the sand of the walk. He, on his side, already grieved and uneasy, called her back in urgent tones. But she ran on without answering, without hearing. Alarmed, and with a heavy heart, he hurried after her, and rounded the clump of plane trees just in time to see her rush into the house like a whirlwind. He darted in after her, ran up the stairs, and struck against the door of her room, which she violently bolted. And here he stopped and grew calm, by a strong effort resisting the desire to cry out, to call her again, to break in the door so as to see her once more, to convince her, to have her all to himself. For a moment he remained motionless, chilled by the deathlike silence of the room, from which not the faintest sound issued. Doubtless she had thrown herself on the bed, and was stifling her cries and her sobs in the pillow. He determined at last to go downstairs again and close the hall door, and then he returned softly and listened, waiting for some sound of moaning. And day was breaking when he went disconsolately to bed, choking back his tears. Thenceforward it was war without mercy. Pascal felt himself spied upon, trapped, menaced. He was no longer master of his house; he had no longer any home. The enemy was always there, forcing him to be constantly on his guard, to lock up everything.

But from the moment he left the house, the doctor had only one desire—to return to it quickly, for he trembled lest he should find his locks forced, and his drawers rifled on his return. He no longer employed the young girl to classify and copy his notes, for several of them had disappeared, as if they had been carried away by the wind. He did not even venture to employ her to correct his proofs, having ascertained that she had cut out of an article an entire passage, the sentiment of which offended her Catholic belief. And thus she remained idle, prowling about the rooms, and having an abundance of time to watch for an occasion which would put in her possession the key of the large press. This was her dream, the plan which she revolved in her mind during her long silence, while her eyes shone and her hands burned with fever—to have the key, to open the press, to take and burn everything in an _auto da fé_ which would be pleasing to God.
