Mary Louise had stood the test of being rich and beloved, and envied by all the daughters of Dorfield; and then of being poor and bereft, pitied by all who had formerly envied her. Soon after the death of her grandfather, Colonel Hathaway, had come the news of her husband's shipwreck. Hope of Danny Dexter's survival was finally abandoned by his sorrowing little wife and his many friends. Colonel Hathaway's comfortable fortune had mysteriously disappeared and Mary Louise faced a future of poverty. With native pluck she arose to the occasion. In spite of her sad heart she showed a cheerful spirit. Joining forces with Josie O'Gorman and Elizabeth Wright in the quaint Higgledy-Piggledy Shop, she opened a millinery department and was soon swamped with orders for smart hats by the elite of Dorfield and old-fashioned bonnets for the ancient ladies who refused to wear hats. When Danny came back, not having gone to a watery grave after all, and the lost fortune was found, Mary Louise again stood the test of being rich and beloved. "Nothing can spoil our Mary Louise," Josie O'Gorman declared, and Irene Macfarlane smiled from her wheel chair.
