Peter Pan in Kensington gardens (1906) by: J.M.Barrie

Peter is a seven-day-old infant who, "like all infants", used to be part bird. Peter has complete faith in his flying abilities, so, upon hearing a discussion of his adult life, he is able to escape out of the window of his London home and return to Kensington Gardens. Upon returning to the Gardens, Peter is shocked to learn from the crow Solomon Caw that he is not still a bird, but more like a human - Solomon says he is crossed between them as a "Betwixt-and-Between". Unfortunately, Peter now knows he cannot fly, so he is stranded in Kensington Gardens.
