With unprecedented access to their hitherto sealed records, this is the first volume of a remarkable official history of ASIO—a revealing and authoritative account of the early years of Australia's national security intelligence service. This book is the winner of the St Ermin's Hotel (London) Intelligence Book of the Year Award 2015.

For the first time, ASIO has opened its archives to an independent historian. With unfettered access to the records, David Horner tells the real story of Australia's domestic intelligence organization, from shaky beginnings to the expulsion of Ivan Skripov in 1963. From the start, ASIO's mission was to catch spies. In the late 1940s, the top secret Venona program revealed details of a Soviet spy ring in Australia, supported by leading Australian communists. David Horner outlines the tactics ASIO used in counter-espionage, from embassy bugging to surveillance of local suspects. His research sheds new light on the Petrov Affair, and details incidents and activities that have never been revealed before. This authoritative and ground-breaking account overturns many myths about ASIO, and offers new insights into broader Australian politics and society in the fraught years of the Cold War. The Spy Catchers is the first of three volumes of The Official History of ASIO.
