This book is a very old book but it is still in print by many publishers. This book is basically a husband and wife team. The wife was the medium and the husband was the interviewer and transcriber of events with ghosts.
I don’t necessarily agree with how they dealt with a lot of the issues that ghosts were having. It was again a different time and a different belief system, see if to take that into account. It’s a very fit book and it’s a long read.
With this book I find it interesting the different authors have not reworked the book but reorganized the book over the years. They also have inserted their own opinion in different places here and there. This book isn’t cheap but maybe you can find some used copies.
This relationship in the book between the wife and the husband reminds me of the relationship between Esther and Jerry Hicks. Esther goes into trance and channels Abraham, a high level entity, and Jerry interviews him. If you haven’t checked out their content-I would highly recommend it.
