Excalibur (L. Ron Hubbard)

Excalibur (alternate titles: Dark Sword, The One Command) is an unpublished manuscript written in 1938 by L. Ron Hubbard, later the founder of Scientology.

Allegedly inspired by this experience, Hubbard composed a manuscript, which was never published, with working titles of The One Command or Excalibur.

[4] In 1962, Hubbard wrote a letter addressed to President Kennedy in which he claimed Soviet agents had stolen a manuscript copy of Excalibur in 1950.

[5] In 1964, Hubbard gave an interview claiming that Soviet agents had "offered him $100,000 and laboratory facilities he needed in the USSR, so that he could complete his work".

By Ackerman's account, Hubbard claimed the near-death experience had occurred not in a dentist's office but on an "operating table" sometime "during the war".

"[3] In a 1949 letter to Ackerman, Hubbard discusses his work "DARK SWORD -cause and cure of nervous tension – properly – THE SCIENCE OF MIND, really EXCALIBUR".

Hubbard promises that the work will give the reader the power to "rape women without their knowing it, communicate suicide messages to your enemies as they sleep, sell the Arroyo Seco Parkway to the mayor for cash, evolve the best way of protecting or destroying communism, and other handy house hold hints.

[10] Hubbard cautions his friend "If you go crazy, remember you were warned", adding that a "good publishing trick" is to require that buyers sign a legal waiver "releasing the author of all responsibilities if the reader goes nuts".

Hubbard referenced Heinlein's earlier work Coventry, in which a utopian government has the ability to psychologically "cure" criminals of violent personality traits.
