I had another quiblet (tip of the cap to Jono!) about 7D -- the use of 'assuming' in the clue. If anything, I would have thought that should indicate the pseudonym was inside the outlaw, not vice versa, but either way I don't recall seeing it before. Other than that, though, lots of fun, and bizarrely swift (for me). Loved 18A -- best homophone for ages!
