one o'clock in the morning
When it was opened , she detained him . `` Robert , see me upstairs , I am frightened . '' Not without some impatience , he followed her up the stairs . Chevalier had waited for Félicie , in the little dining-room , before the armour which she had worn as Jeanne d'Arc , together with Madame Nanteuil , until one o'clock in the morning . He had left at that hour , and had watched for her on the pavement , and on seeing the cab stop in front of the door he had concealed himself behind a tree . He knew very well that she would return with Ligny ; but when he saw them together it was as if the earth had yawned beneath him , and , so that he should not fall to the ground , he had clutched the trunk of the tree . He remained until Ligny had emerged from the house ; he watched him as , wrapped in his fur coat , he got into the cab , took a couple of steps as if to spring on him , stopped short , and then with long strides went down the boulevard .
