eleven o'clock
Only when she had told him would she be sure of herself . Her word once given there could be no withdrawal . It was nearly midnight but she knew he rarely left his study until later . Peters would be gone , he was methodical in his habits and retired punctually at eleven o'clock with a regularity that was unvarying . She was sure of finding him alone . She dared not wait until the morning , she must go now while she had the courage . Delay might bring new doubts , new uncertainty .
