When this author actually approaches the subject of ghosts etc. then most of what he has to say is fascinating, although he seems to imagine that he's the only proper authority on such matters and is very patronising about those of us who do not have an extensive historical training. Why this should be particularly important I can't imagine, since ghosts are not always (by any means) exclusively associated with ancient history, and as there are no clear 'rules' anyway he can hardly call all the shots! I've noted a number of occasions where he totally contradicts himself regarding his own directives on the subject, which is quite amusing. Shame he's dead - I'd have liked to have been able to challenge him personally since I've been having 'interesting experiences' all my life and am only an 'expert' on ballet, dollshouses and dogs! On the whole, though, this is one great long lesson in American history, coupled with the author's own theories on certain controversial issues, some of which are frankly very dodgy indeed, all things considered.He has favourite mediums and quotes long and verbatim from sometimes nonsensical exchanges that left me yawning widely, and of course there's no way of proving any of his claims that whoever it was 'couldn't possibly have known about it beforehand'...Any medium worth his/her salt would probably know all the ghostly goings-on (and the attendant nonsense)in major buildings such as Jefferson's house, and all sorts of odd info can be found on the Internet that can be construed as being 'impossible' to have known beforehand. As an Englishwoman eager for news of other people's experiences in ghostly matters, this is a very disappointing book, no matter how many pages it might have, and none of it is new. Should never have been allowed!
