Why did I love this book?
I wrote a novel, a thriller set in and around Westminster, a place I know well because I was a senior civil servant in Whitehall for many years. This included a number of little-known and ancient subterranean locations, including Roman baths, plague pits, the sewers, the Underground, the 'lost' River Tyburn, and World War Two bunkers. The Subterranean Guide filled in the blanks in my knowledge and opened up other aspects of this hidden world to me. It's a treasure trove of information and written with a light touch that engages everyone from the casual reader to the history geeks like me.
