Mary-Alice Arceneaux has decided to make her home in Sinful! Mayor Celia's sweet-natured and curious cousin is eager to settle into small-town life after moving from the big city (Mudbug, Louisiana). But before Mary-Alice can even unpack her bags, a man of the cloth dies under mysterious circumstances, a device with strange powers turns up in the glove box of her Oldsmobile 88, and her new friends, Ida Belle, Gertie, and young Fortune, are behaving oddly...even for Baptists.
