Sad loss.....I didn't know he wrote children's books! A man of many talents e.g. also a director (of several Python films), historian, presenter and - of course - a writer (largely with Michael Palin).
Many will remember him for the classic 'he's NOT the Messiah - he's a very naughty boy!' which was based on his own mother! 🤪
It is necessary, therefore it is possible.
