The Cat Who Came in off the Roof by Annie M. G. Schmidt is a chapter book aimed at independent readers. It tells the story of Tibble, a reporter at his local newspaper who struggles for inspiration when his editor complains that all his articles are about cats. Until one day he helps to rescue Minou, a young woman who has become stuck up a tree after being chased by a dog.
To his surprise, Tibble soon learns that in fact Minou is a cat who has been changed into a woman. She still behaves a lot like a cat though, and can still talk to them, which comes in very handy when he is on the hunt for insider information about local goings on.
