In this story Wilbur sees a woman dressed in a gray cloak leave his wife Lydia's room. They don't know the woman and had not let her in. So who is she? How did she get into the room? Why did she come? She can't have been a ghost, or can she? Wilbur wants to know and decides to solve this mystery.
I'm one who loves mysterious things and books with mystery in them. So for me this book was simply wonderful.
