She handed Barbara a letter which Miss Stuart had received from Mrs. Post only a few minutes before , and which read : My Dear Miss Stuart , We want , in some quiet fashion , to show our appreciation of , and thanks to , the little girl who so patiently and cleverly kept her own counsel , and so materially aided in the discovery of the jewel thief . I feel that I did not do her justice . Governor Post and I both believe that it is to her wit and courage that I owe the return of my emerald necklace . I have talked matters over with Hugh , and , with your consent , I should like to give a luncheon , in her honor , on board the yacht at one o'clock to-morrow . We will spend the afternoon sailing in the bay . Only our intimate friends will be invited and we feel that no party could be complete , at Newport , without the presence of `` The Automobile Girls . '' Faithfully yours , Katherine Post .
