This book is written on second hand, unreliable info, just the kind of "I heard that...".
Peter Tompkins is the kind of writer who likes to compile things from other sources. But this time the content is poor, low quality, just sounds as fake as possible, he could really have done better.
If you are interested in Fairies, no doubt you will be able to find better reading elsewhere.

This is a most excellent book, covering material not generally available to the spiritually curious. I have been completeing a Doctors Thesis with The University of Metaphysics and find this to be one of the books I used most extensively in the thesis. Interestingly enough this gives a more complete story of the movie FAIRY TALE A TRUE STORY. A movie which portrays Sir Arthur Conan Doyles discovery and publishing of the famous Cottingsley fairy pictures As a spiritual hypnotherapist (C.M.Ht//Certified Master Hypnotherapist) I am able to validate some of this material from my research sessions. I wish you would make a better effort to supply this book, which is on my list of 10 most recommended books to students and clients.
