The special services of many countries in the turbulent twentieth century studied and used the paranormal and psychic capabilities of people for their own purposes, although classical science still cannot explain the nature of these phenomena. Despite the extreme secrecy of these developments, special methods are migrated from intelligence to politics both to obtain and to suggest to anyone the necessary information. And there are many similar examples - be it the discovery of secret special facilities, the prevention of conspiracies, terrorist attacks, or the inexplicable suicides of political opponents - in the sensational book of O. Gray. The reader can touch those secrets of the world's leading intelligence services into which mere mortals will never be dedicated.
