Three of the characters in the third novel, The Aqueous Solution, have some significant moments together at Blue Spring Heritage Center just west of Eureka Springs. The spring itself also figures prominently in a moment shared by two characters in the first novel, The Water Cure. The long-time attraction is a place of great beauty and rich heritage. The museum building features quite a lot of memorabilia from The North Arkansas Line railroad as well.
