This is a factual book about one psychiatrist's belief that people could predict disasters. There is a lot in this book about the Aberfan tragedy and there really was a Premonitions Bureau. The book doesn't seem to come to any conclusions about whether disasters can be predicted and the predictions made were so vague as to be just about impossible to send out warnings beforehand.
I enjoyed this for what it was and read the whole book. Still, it turned out to be quite disappointing insofar as the predictions made were too vague to do anything about and were only related to the circumstances after the fact, and even at that not wholly convincingly.
Not as interesting as I thought it would be.
