Listening to Into the Woods, I am reminded of David Wilson's wonderful tragic novel, The Coachman Rat, about the rat the fairy godmother changed into Cinderella's coachman, The story is about a rat treated kindly by a young girl with a fairy godmother. After she marries the Prince, the word gets out that she is a witch, and the peasants storm the castle, killing everyone and executing Cinderella as a witch. The story ends with this man straddling the worlds of rats and men, as the Pied Piper leading the rats of Hamelin to their deaths. It's one of the most haunting books I know.
