What is the author's tone in J.M. Barrie & the Lost Boys by Andrew Birkin?

The tone used in "JM Barrie and the Lost Boys" by Andrew Birkin is objective. It is clear that Birkin has done an exhaustive amount of research in preparing this book, as is shown in the amount of detail along with reprints of letters, playbills, and family photographs.

While the tone of the book is objective, there is an underlying fondness there which gives the reader the sense that Birkin was close to the Barries and/or the Llewelyn Davies family. The details of the story are written about real people, not just about a piece of literature on a dusty shelf. This most certainly comes from the relationship between Birkin, Sharon Goode and Nico Llewelyn Davies. Between the three there were about 600 letters exchanged in the making of the NBC miniseries, plus much time spent at Nico's house in the country. Those experiences added a sense of richness to the tone of the book that no other could have equaled.
