`` Let 's go and sit down upon the Terrace and talk about her . '' `` But , my dear Dicky , '' his sister protested , `` I do n't want to sit upon the Terrace . I am going to my dressmaker 's across the way there , and afterwards to Lucie 's to try on some hats . Then I am going back to the hotel for an hour 's rest and to prink , and afterwards into the Sporting Club at four o'clock . That 's my programme . I shall be doing what I can the whole of the time . I shall make discreet enquiries of my dressmaker , who knows everybody , and I sha 'n' t let a single acquaintance go by .
