`` How delightful , and how very kind of you ! '' said Sophy . `` I am sure I can manage -- as long as I am in by nine o'clock . '' `` But why nine o'clock , my dear Cinderella ? '' `` Because I have to interview the cook when he returns from the bazaar . Herr Krauss is something of a gourmand and rather querulous about his food , and he often brings in one or two men to tiffin or dinner . '' `` A nice , amusing change , '' said Shafto .
