one o'clock
In the meantime I must write on , lest despair overwhelm me . Once during the night I thought I heard a footstep outside . I rushed to the window and looked out , but there was nothing to see , no sound to hear . That was a little after one o'clock . I feared to go outside , lest that should alarm her ; so I came back to my table . I could not write , but I sat as if writing for a while . But I could not stand it , so rose and walked about the room .
