Comment from the book world in May 2017

'If you're ever lucky enough to score an early success as a writer, as happened to me with The Spy Who Came in from the Cold, for the rest of your life there's a before-the-fall and an after-the-fall. You look back at the books you wrote before the searchlight picked you out and they read like the books of your innocence; and the books after it, in your low moments, like the strivings of a man on trial. ‘Trying too hard' the critics cry. I never thought I was trying too hard. I reckoned I owed it to my success to get the best out of myself, and by and large, however good or bad the best was, that was what I did.

And I love writing. I love doing what I'm doing at this moment, scribbling away like a man in hiding at a poky desk on a blackclouded early morning in May, with the mountain rain scuttling down the window and no excuse for tramping down to the railway station under an umbrella because the International New York Times doesn't arrive until lunchtime.

I love writing on the hoof, in notebooks on walks, in trains and cafés, then scurrying home to pick over my booty. When I am in Hampstead there is a bench I favour on the Heath, tucked under a spreading tree and set apart from its companions, and that's where I like to scribble. I have only ever written by hand. Arrogantly perhaps, I prefer to remain with the centuries-old tradition of unmechanized writing. The lapsed graphic artist in me actually enjoys drawing the words...'
