'A thoughtful, authoritative and penetrating analysis of the role intelligence has played in the making of foreign and security policy. Mark Huband draws on his relationship of trust with the intelligence world to give a sympathetic but far from uncritical account of intelligence work and the challenges it faces in the information age. A book to read and re-read.' Nigel Inskter, International Institute for Strategic Studies 'Mark Huband has been to all the right places, meeting spies, jihadis and others who live in the shadows. Melding anecdote with analysis, he provides a robust critique of MI6 and the CIA, drawing parallels between Ireland, the Cold War in Africa, Iraq and the 'global war on terror.' Both thought-provoking and gripping, Trading Secrets is the essential book for those who want to understand how the spooks operate and why they get things wrong.'
