Dear Sir Cornwell,
I just finished reading all of your books pertaining to the middle ages, Saxons and Archer’s Tales culminating with your last book 1356.  1356 was an excellent read and as in all of your books a chance to live vicariously with your character’s great adventures.
Hopefully, you will continue your stories after France started gaining back their reputation with battle successes (I assume they did at some point?).
Your books are like coffee and one acquires an addiction to the adventures of Lord Derfel and Sir Thomas.  So, write some more and thanks for the ones you did write.
Best,
JD Miles
