`` Very good , my child , '' commented David . `` However , what I was about to say was this : My party is not to be in a house . It is an open-air party . We are to meet at the Omnibus House , to-morrow afternoon at four o'clock . Two very distinguished gentlemen have also been invited -- Mr. Reddy Brooks and Mr. Hippy Wingate . '' A shout of laughter went up from the girls `` Distinguished , indeed , '' cried Nora . `` It will be a delightful party I am sure . ''
