The Clever Miss Jancy
by Margaret S. Haycraft
Miss Orabel Jancy is indeed clever, and she knows it. She is the author of several scientific books. When Orabel was born, a deathbed promise was made with a friend that Orabel and the friend's son should be given the opportunity to marry. Orabel only learns of the arrangement when she is grown up and the friend's son is already on his way from India -- to propose to her!
