" The sight of his brother and the proximity of death renewed in Levin's soul that feeling of horror at the inscrutability, nearness and inevitability of death which had seized him on that autumn evening when his brother had arrived in the country. That feeling was now stronger even than before; he felt even less able than before to understand the meaning of death, and its inevitability appeared yet more terrible to him; but now, thanks to his wife's presence, that feeling did not drive him to despair; in spite of death, he felt the necessity of living and loving. He felt that love had saved him from despair, and that that love under the menace of despair grew still stronger and purer.

Scarcely had the unexplained mystery of death been enacted before his eyes when another mystery just as inexplicable presented itself, calling to love and life.

The doctor confirmed their supposition about Kitty. Her illness was pregnancy. "
