Swift water

Jean Randolph spoilt rich girl with her terrible twin alter ego and Christopher the preacher in small town Garston strike sparks. Jean has a mentally separated father and mother. This is more religious romance than the usual genre of Emilie Loring and more like Grace Livingston Hill's books. The focus on church and religion is slightly over the top including a reference to a figure filled with light and a drawn sword an enemy of Christopher who wants to injure him sees. The character of Jean is well drawn though. Lewiston Daily Sun has this serialized from April 1940 and you can read it through google news archives
