His books Geheimgesellschaften (Secret Societies) and Geheimgesellschaften 2 have been banned in Germany, France and Switzerland for inciting anti-semitic hatred.
The majority of his books, such as Die Kinder des neuen Jahrtausends. Mediale Kinder verändern die Welt (Children of the New Millennium, and how They Change the World) are non-political and deal exclusively with esoteric subjects.
Holey chose his nom de plume "van Helsing", after he read Bram Stoker’s vampire-novel Dracula at the age of fourteen.
Today, Holey runs his own publishing house, which publishes his works and the works of others who hold similar interests and viewpoints, as well as a brothel in Frankfurt am Main. Recently he has started a new online publishing company together with Ralf U. Hill (also a writer of right wing and revisionist books) called Zeitstrom Verlag.
The Landesamt für Verfassungsschutz Baden-Württemberg (an office entrusted with protecting the German constitution) first referred to Holey in a 1996 report entitled: "Rechtsextremistische Einflußnahme auf die Esoterikszene" (Extreme Right-Wing Influences within the Esoteric Scene).
Holey draws from many esoteric and conspiracy theories, many of which originate in the United States of America. His writings encompass such varied themes as Nostradamus, reincarnation, conspiracy theories regarding John F. Kennedy and Uwe Barschel's murders. According to his detractors, Holey's books are largely plagiarized from other sources, many of which are conspiracy theorists of questionable repute. The author believes he is banned as part of a larger conspiracy.
In Geheimgesellschaften, Holey combines science-fiction, esotericism, Nazi-mythology, ufology and "Zionist global domination" theories. He also employs The Protocols of the Elders of Zion as a source. He believes the Rothschilds head a Jewish conspiracy to rule the world, and associates them with a mysterious cabal called the "Illuminati," who plan a New World Order. Holey and his followers claim that they are not anti-semitic, but rather that they speak out against powerful Jewish interests in high finance and politics.
