nine o'clock
They spent the evening , Olivier kneeling by his sister 's side while she petted him like a child . They hardly spoke at all . They could not even be happy , for they were too worn out . They went to bed before nine o'clock and slept the sleep of the just . Next day Antoinette had a frightful headache , but there was such a load taken from her heart ! Olivier felt , for the first time in his life , that he could breathe freely . He was saved , she was saved , she had accomplished her task : and he had shown himself to be not unworthy of his sister 's expectations !
