This book from 1902 introduces the first appearance of Peter Pan who is to be found wandering London's Kensington Gardens at night. However, this only takes up a very few chapters in the book. The rest being the story told by a man about his relationship with a little boy and the boy's mother. (Goodreads)
Sir James Matthew Barrie, (9 May 1860 – 19 June 1937) was a Scottish novelist and playwright, best remembered today as the creator of Peter Pan. He was born and educated in Scotland but moved to London, where he wrote a number of successful novels and plays. There he met the Llewelyn Davies boys, who inspired him to write about a baby boy who has magical adventures in Kensington Gardens (included in The Little White Bird), then to write Peter Pan, or The Boy Who Wouldn't Grow Up, a "fairy play" about an ageless boy and an ordinary girl named Wendy who have adventures in the fantasy setting of Neverland.
