In High Places by Arthur Hailey
 
As events bubbles to a scalding boil, leaders of two great nations fought in desperate secrecy to keep the lid on the world. Bartering, backstabbing, browbeating, bribing...and praying for a little more weight to throw on the delicate balance of international power. This is a novel of men at the summit, their bold deals and soiled souls -- and their women, clutching at fevered moments as the time for loving, the time for living, slipped so quickly away.
