DavidG - oddly, the only character I added from whole cloth was Miss Ward at the Library.
Everyone else is mentioned (though not necessarily by a name) in the original story - Armitage's wife and doctor, "five policemen down from Aylsbury", and the variety of townsfolk (pared down from about 20 mentioned to about 7). Even my "Widow Zebulon" originated with "Old Zebulon Whateley" - just that Rhys did such a good job reading the role, I swapped the gender to give it to her!

I'm just sneaky that way.....
I did push around the events to make it more active and cinematic, though.
