Richard Blade is an adult fantasy paperback novel series produced by American publisher Pinnacle Books between 1969 and 1984.
During the story, he would have explicitly described sexual encounters with beautiful women (both in England and in the alternate dimensions), and would usually return from his adventure with some item, or bit of knowledge useful to Britain (the ostensible reason for his being sent).
All of the stories are set in England (at least at the beginning and end, with Blade’s being teleported to some other dimension for the bulk of each tale).
Sources:[1][2] During the early 1990s the Russian publishers could secure the rights only to the first six books of the series, and asked the translator, Mikhail Akhmanov, to write the further adventures of Richard Blade.
He forms with Patrick Eris a duo dedicated to offering quality popular literature (in the noble sense of the term).
