"My house at Obernai."

A movement of stupefaction made the father and son both straighten themselves. The house at Obernai? The home of the Biehlers? The son at least understood the sacrifice which the mother was making, and he rose and kissed her tenderly.

"Just the time to let M. de Farnow know about it. You will fix the day and the hour—write to him when he answers you."

Lucienne, in spite of her want of tenderness, drew closer to her mother that evening. In the little drawing-room, where she worked at crochet for two hours, she sat near Madame Oberlé, and with her watchful eyes she followed, or tried to follow, the thoughts on the lined face so mobile and still so expressive. But often one can only partly read what is passing in a mind. Neither Lucienne nor Jean guessed the reason which had so quickly prompted Madame Oberlé's act of self-sacrifice.
