The Great British Dream Factory: The Strange History of Our National Imagination

Context:

Dominic's own book, mentioned early in the episode when Tom introduces it as a book about the impact of British culture on the world's imagination. Dominic admits he underrated Harry Potter in the book and was 'very rude about it.' The book contains analysis of J.K. Rowling and the school story tradition, including a footnote pedantically noting that Hogwarts couldn't have been a castle before the Norman Conquest.
