The total copies of his novels sold, including paperbacks and booklets, is over 270 million. Don Harris is an agent for the European Secret Intelligence, or ESI. Ever since he was young he has possessed extrasensory abilities, particularly clairvoyance, a sort of third eye, inherited from his ancestors the psychonauts a fact he is still unaware of. ESI agent Nancy Goldman has just been killed in London. Investigating the murder with the help of his telepathic abilities, Don Harris discovers who is responsible: the Club of the Sons of Hell, a sect-like organisation whose goal is unlimited economic and political power. Harris hunts a killer who does the dirty work for the Sons of Hell and who also possesses extrasensory powers. In an abandoned chapel it comes to a duel between the two Psi-masters. The killer, psychically wounded in the battle, can only mutter incoherently about the Club of the Sons of Hell. But Don Harris has another clue to follow. This leads to the lawyer Archie Ramsay, who, however, was killed the day before. In the lawyers office the Psycho-Cop finds vital information, including a map of the region of Glastonbury: a place know as the English Jerusalem, and, coincidentally, the traditional home of Don Harriss family. There is also a map of Stonehenge and a reference to a particular night of a full moon one that is only 48 hours away \] Press Germanys most successful writer by far.
