Just remembered I never updated!
The podcast did reveal more about the names. For Urban Bedford it was a reference to Urbain Grandier, a French preist burned at the stake after being convicted of witchcraft - a fascinating story actually. Curt was named as he was exactly that, rudely brief. Mr D Webster, the D stood for Daniel in reference to ‘The Devil and Daniel Webster’, where the lawyer argued his way out of a pact with the devil. All very clever, as always.
