Therefore, it is likely that he writes in various locations, including:
* His home in Devon: This is a likely setting, given his love for the countryside and the sea.
* Other locations in the UK: He may travel to different areas for research or inspiration.
* National Theatre: He might write there due to his connection with the theatre, or perhaps while working on adaptations of his books.
While we may not know his exact writing location, his works often reflect his love for the natural world and his fascination with history.
