Le Carre's superior writing still shows although sentimentality spoils some bits...the story has a good twist but the writer's understandable abhorrence of right wing nasties and fools clouds his narrative so much that the denouement feels too pat and too flat...somewhat like a movie on spying that starts with plenty of grey but after the middle bit is in a hurry to produce a happy ending...this book of course leaves open the question what may happen to the two protagonist couples...so it's less than a silly movie style happy ending but by Le Carre standards, it's a surprisingly flaky end to a story...
