This book will not teach you how to unearth the dirty secrets of dictators, catch arms dealers or transport secret messages across the border.

David Omand, a former high-ranking British intelligence officer, talks about the main skill of an intelligence officer - to take correct decisions based on limited, incomplete, and sometimes simply unreliable information. From his book you will learn what to do when you do not have time to check the facts, how to learn not to panic, not fall into a stupor, correctly assess risks, ignore conspiracy theories and expose liars and manipulators.

The author's method of working with information is based on many years of experience of intelligence officers and analysts from different countries, perfected during events such as the Falklands War or the Caribbean Crisis. Separate chapters of the book are devoted to negotiating and establishing trust in various circumstances.
