To coincide with the publication of upcoming sequel Peter Pan in Scarlet, Alan Yentob presents a documentary which explores why JM Barrie's character has such lasting power and mythical status and looks at the secret behind its eternal appeal. He goes in search of the real JM Barrie, visiting the remote Scottish island of Eilean Shona, his home town of Kirriemuir near Dundee, Black Lake in Surrey where Barrie played, and Kensington Gardens, where Peter Pan was born.
