In 2001 a young English composer called Will Todd wrote a two act opera (libretist Ben Dunwell) called The Blackened Man. This opera is based on the story of Will Jobling. You will see by visiting Todd's website that the opera has been a great success and may be performed again next February in Durham, art grants permitting. I would imagine the libretist would have done an immense amount of research on Jobling and would maybe know as much about him as anyone. Hope this helps!
