I am a  part-time student at the University of Bolton ,UK , and I am currently researching for my final 2nd year project  about the relative difficulty between finding accurate information  in different eras of historical fiction – for example, how hard it is to write about the Anglo-Saxon era in comparison to the Napoleonic Wars.  I was hoping that you could help me out by telling me how hard  (or easy) it was to  research the various periods of history that you have written about.
yours sincerely,
