Described as 'perhaps the single most notorious book ever written about Jack the Ripper,' presenting a conspiracy theory involving Prince Albert Victor, Walter Sickert, and the Freemasons. Compared to Graham Hancock or Eric von Daniken in terms of disproportionate impact relative to plausibility.

Described as a 'mad' book proposing a conspiracy theory involving the royal family and Masons, with the hosts noting they would discuss it further in a later episode.
