midnight
The `` Automobile Girls '' were talking over their costumes when there came a rap on their door . Grace responded , to find the corridor empty ; but at her feet lay a sealed envelope addressed to Barbara , who hastily tore it open and read aloud the enclosed note . `` Maud and the Count have planned to elope during the domino ball . At midnight Maud and her chaperon will steal out of the side entrance of the hotel . The chaperon will wear a black domino , but will remain in her room until ten minutes before midnight , when she will go to the veranda , meet Maud , and the two will go to the east entrance of the hotel grounds , where they will be met by the count with an automobile . They will go to the village and be married there . Arrangements have been made and the license secured .
