Tibble is a reporter. He only ever writes about cats, and he's about to be fired. Minou is a young woman who has moved into Tibble's flat. She hates dogs, likes rooftops, loves the fishmonger, and happens to have been, until very recently, a cat. With her feline friends listening out for all the local human news, is Minou the answer to all Tibble's problems - or just the beginning of them?
