On his 2008 US tour, Brian Jacques has revealed the title of his 21st Redwall novel: The Sable Quean! Brian has explained that "quean" is an old English term for a "wicked lady"; indeed the technical definition of the word is an "impudent" or "disreputable" woman, and often times was used to described a prostitute, however that is obviously not what Brian means by the word. I do think it is fair to insinuate the main antagonist will be female, and that "quean" is also a play of words on "queen". Stay tuned as this story continues to develop.
