One thing about London is that when you step out into the night, it swallows you.

People never explain to you exactly what they think and feel and how their thoughts and feelings work, do they? They don't have time. Or the right words. But that's what books do.

There arent many great passages written about food, but I love one by George Millar, who worked for the SOE in the second world war and wrote a book called Horned Pigeon.
