Madhyastha by Frederick Forsyth

The kidnapping of a young man on a country road in Oxfordshire is but the first brutal step in a ruthless plan to force the President of the United States out of office. If it succeeds, he will be psychologically and emotionally destroyed. Only one man can stop it - Quinn, the world`s foremost Negotiator, who must bargain for the life of an innocent man, unaware that ransom was never the kidnapper`s real objective . . . The Negotiator unfolds with the spellbinding excitement, unceasing surprise and riveting detail that are the hallmarks of Frederick Forsyth, the master storyteller.
