'Captivated' provides a deeply disturbing insight into the background of the story of Peter Pan. Dudgeon's book is a revelation in many ways and extremely thought-provoking.
However, I do have several criticisms: first, there is an awful lot of guesswork in this book. Dudgeon will admit to using supposition to reach a conclusion, but then will base facts on these suppositions. For example, he makes a tenuous claim that Jack Llewellyn Davies had depression due to his lung disease - this despite blaming JM Barrie for all possible mental health issues which impacted the rest of Jack's family.
Barrie is blamed for any and all disasters to befall the Davies and Du Maurier family - though he was clearly a strong and charismatic character, my feeling is that Dudgeon stretches the tales of Barrie's power too far at times.
This book obviously stems from very in-depth research: unfortunately this leads me to my greatest frustration with this book - the referencing. Dudgeon uses an incredibly irritating system whereby he lists each chapter's references separately so that, in order to check a reference, you first must check which section of the book you are in and which chapter you are reading - by then, you have forgotten the reference number so have to go back to the page you are reading - all of which severely interrupts the flow of your reading! Why not just number each reference continually?
Further, whilst some referencing is obsessive, there are many times when quotes appear with no reference whatsoever and with no hint to where they come from. This is not only unhelpful but it is also unprofessional and something the publisher should have picked up on. Further evidence of poor proof-reading is clear on page 206, where the wrong reference is given!
Dudgeon quotes Margaret Forster's criticism of Daphne du Maurier for mixing fact 'in the most awkward fashion with entirely imaginary suppositions, greatly to [the book's] detriment'. An interesting quote and one which could well serve as a warning to Mr. Dudgeon.
