My Grandmother is listening to this book on cd and she told me there is a character named Lorraine (Father Tim stops by her house to check on her and finds her door open.)
But she doesn't remember who Lorraine is from previous books.

(view spoiler)[No, no. Lorraine (actually, Louella) is the best friend of Sadie- in the first few books, they were like peas in a pod. When Sadie dies, her money is used to build Hope House, and Louella is specifically able to live there. (hide spoiler)]
