This series was originally aired as the first pay-per-view series offered via a multichannel television service (DirecTV), and contained nudity and extended scenes. The syndicated version on TV and DVD releases have been edited.
Is this based off of Sir Arthur Conan Doyle's book?

Yes, it is based off the book of the same name. It is essentially the same story, with little changes. The character of Veronica was not featured in the book, and is a character original to the television series.
