Book excerpt: The Shadow World presents the behind-the-scenes tale of the global arms trade, exposing in forensic detail the deadly collusion that too often exists among senior politicians, weapons manufacturers, felonious arms dealers, and the military--a situation that compromises our security and undermines our democracy. Now a major PBS documentary "An authoritative guide to the business of war. Chilling, heartbreaking, and enraging."--Arundhati Roy Andrew Feinstein reveals the cover-ups behind a range of weapons deals, from the largest in history--between the British and Saudi governments---to the guns-for-diamonds deals in Africa and the current $60 billion U.S. weapons contract with Saudi Arabia. Based on pathbreaking reporting and unprecedented access to top-secret information, The Shadow World takes us into a clandestine realm that is as vitally important as it is shocking.
