JAK P. MALLMANN SHOWELL's first book, U-boats under the Swastika, is one of the longest selling naval books in Germany and his second, The German Navy in World War Two, was named as one of the outstanding books of the year. Ten years ago he became involved in a series of supernatural experiences and has been studying these ever since. Not wanting to believe anything written in books, he started attending courses and working with experts such as hypnotherapists, semi-professional dowsers and Buddhist monks. In addition to this he has conducted his own research by devising a large number of fascinating experiments to investigate all manner of strange occurrences. TONI HUGHES has a university degree in environmental sciences and has been the High Priestess of Bill Love's Wicca coven for twenty years.
