A Colder War, Cumming - B +

                                             Tom Kell has been benched by MI-6 for passively participating in a joint venture with the Cousins that involved someone being rendered to Guantanamo.  Its has been in the process of being "looked into" for a year-and-a-half when the Chief asks him to do a personal favor - try and sort out why one of their mutual friends, Paul Wallinger, an  agent in Turkey, flew his Cessna into the side of a mountain.  A few weeks into the process, the Chief also tells him of her suspicions of a mole and offers him a chance to come back in from the cold. So he's off, but everywhere he turns bodies keep piling up. First, the Greek flight engineer who worked on Paul's plane commits suicide. Then Paul's mistress in Croatia, whom Tom believes is working for the Hungarian intelligence service is found dead.  After six weeks of intensive spying on the likely candidate, the mole is found in Istanbul, a disaffected Yank working for the Russkis.  The Brits proceed to try to take him in without an assist from the CIA.  I won't divulge the finale, but suffice it to say, it's a pretty good tale. I have enjoyed this so much that I've already downloaded the earlier book by the author about Tom Kell.
