one
o’clock
Alexey Alexandrovitch had seen nothing striking or improper in the fact that his wife was sitting with Vronsky at a table apart , in eager conversation with him about something . But he noticed that to the rest of the party this appeared something striking and improper , and for that reason it seemed to him too to be improper . He made up his mind that he must speak of it to his wife . On reaching home Alexey Alexandrovitch went to his study , as he usually did , seated himself in his low chair , opened a book on the Papacy at the place where he had laid the paper-knife in it , and read till one o'clock , just as he usually did . But from time to time he rubbed his high forehead and shook his head , as though to drive away something . At his usual time he got up and made his toilet for the night . Anna Arkadyevna had not yet come in .
