I hope I succeed in demonstrating that you may equally find compelling and significant narratives - stories that alter or add to our understanding of history - in unprepossessing places: a Victorian sewer system; a Cold War bunker; derelict hospitals.

I was brought up in a house where I was so aware of a life that had been broken by politics and conflict.

I don't know why, but I think the eating of food is hugely enhanced when you do it on a train. Even a simple steak and chips, when the world is rushing past outside, can take you to heaven.

What is it about trains that makes food taste so good? Some of my happiest memories are of prolonged lunches between St. Moritz and Zurich, Bordeaux and Paris, and even between Coimbra and Salamanca.

Honestly, I think there's a cycle to the popularity of fantasy and fairytales that usually coincides with times of unrest or hardship in our own world. By retelling these legends or immersing ourselves in fantasy realms, we can safely explore the very real, very day-to-day darkness of our own lives.

It's been a huge blessing, being able to travel and have a great life.

The lesson of travel seems to be so banal, but so great, which is that people are just so amazingly decent the world over. Given the disparity of income and wealth, it's amazing not just that you don't get robbed everywhere - it's amazing you don't get eaten.

Whether it's as the hero of an adventure story, as teacher and friend, as icon on watch, shirt or hat - everyone knows Mickey Mouse.
