two o’clock
Half an hour later the house was locked , and the crazy old man was wandering along through the rooms in excited expectation of hearing every minute the five knocks agreed upon . Now and then he peered out into the darkness , seeing nothing . It was very late , but Ivan was still awake and reflecting . He sat up late that night , till two o'clock . But we will not give an account of his thoughts , and this is not the place to look into that soul -- its turn will come . And even if one tried , it would be very hard to give an account of them , for there were no thoughts in his brain , but something very vague , and , above all , intense excitement . He felt himself that he had lost his bearings .
