Peter Pan's Brother

This book is a sequel to Barrie's "Peter Pan". It tells how Peter is turned into an old man by an evil spell and it devolves on his younger brother Horace, an eccentric little boy, to save him. In the course of this Horace discovers a nasty surprise about his parents. Care has been taken with the sense of period (e,g. houses have coal fires in bedrooms). The location is partly in Kensington Gardens and partly in Neverland.
