What le Carré is so good at is unpicking something very specific about Englishness. That is almost part of why I think he wrote the novel. You can feel le Carré's anger that someone who has had the benefits of an English education and an English upbringing is using that privilege to basically do the worst things imaginable. There is an anger in the book about that.

I THINK IF YOU'RE GOING TO BE CONVENTIONALLY ROMANTIC YOU'VE GOT TO GO ALL THE WAY: A BEAUTIFUL DINNER SOMEWHERE LOVELY, WITH BOAT-LOADS OF FLOWERS, CHOCOLATES AND CHAMPAGNE.

Actors in any capacity, artists of any stripe, are inspired by their curiosity, by their desire to explore all quarters of life, in light and in dark, and reflect what they find in their work.

All acting is an act of imagination. You are simply conjuring up imaginary circumstances in your mind and responding truthfully to them.
