The 9th Revolution

Charles Manson, The Beatles, Polanski's Rosemary's Baby and satanism -- how do all of these elements connect to the horrible suicide of Detective Dick Dixon's younger sister? Has the Manson Family somehow come back from a turbulent past for one more try at Helter Skelter? In order to find out, Dixon must throw himself into a haunted, darkened corner of the world where satanic cults, diabolic hypnotists, witches covens and neo-Manson Family members thrive and conspire against him.
It is a timorous, inexorable descent into which the detective is forced to follow, not only to save himself, but anyone he has ever cared for.
