eight o'clock
Except that they did not refer to the expected temporary chaperon , they discussed all the details of the evening 's party . Many of the courses of the dinner they dismissed without tasting , and so , by half-past seven , Patty was back in her own rooms , and Mrs. Hastings appeared promptly at the hour . A maid named Janet had been appointed to look after Patty personally , but she was dismissed , with instructions to return at eight , and then Patty began her transformation scene . It was not accomplished without some few difficulties , and much giggling , but by eight o'clock , Patty and Mona surveyed a most acceptable looking chaperon , due to their own handiwork . Susan , or Mrs. Hastings , as they called her , looked the picture of a kindly , dignified matron . Her grey hair was done in a simple , becoming fashion , and ornamented with a spray of silver tinsel leaves . The grey satin gown of Mrs. Allen 's , which Patty had appropriated without compunction , fitted fairly well , and a fichu of old lace , prettily draped , concealed any deficiencies .
