six o'clock
But you would not be comfortable without changing your dress , and the mornings are still sharp . This is how it must be . I will slip away before long , and make all preparation necessary . I will get a bagarino and a pony -- not from the Castelmare stables , you understand , but from a man I know and can trust -- and I will come with it to the door of your lodging at six o'clock . You will stay at the ball till the end . Everybody will go by four o'clock , or soon after . That will give you plenty of time to change your dress .
