Great review Marc, thanks.
I love Graham Greene novels, though I've never really bothered with the films. We're getting a full Greene series here, you looked at 'Down and Out' and we're getting 'Brighton Rock next? Proper treat!
Have you read 'The Power and the Glory'? (I think there was a film made of that sometime in the 60s?)
I think though, that 'The End of the Affair' has to be my favourite Greene novel (only cemented by the audiobook version I picked up a few years back which is sublimely read by Colin Firth).
Anyway, great piece of work, I'm looking forward to more ;D
