Aunt Jane's Nieces at Millville by L. Frank Baum writing as Edith Van Dyne is the third book in a series written for young girls. It was originally published in 1908. The three nieces are Louise Merrick, Elizabeth De Graf, and Patsy Doyle and in this book they go to a fictional upstate New York town called Millville for the summer with their rich uncle John who has gotten a farmhouse there as payment for a bad debt. Much of the novel deals with the vast cultural differences between the small town farmers of the town and the rich "nabobs" living in the summer house. Soon after moving in the three young women sense a mystery in the sudden death of the previous owner of the house, a seaman named Captain Wegg, and the disappearance of his fortune. Suspecting murder and theft, each of the nieces has her own theory as to what happened and who may be guilty. The plot develops nicely providing a pleasant mystery/detective book with a happy ending.
