Spy Catcher: The Candid Autobiography of a Senior Intelligence Officer by Peter Wright, Paul Greengrass

Spycatcher: The Candid Autobiography of a Senior Intelligence Officer is a memoir written by Peter Wright, former MI5 officer and Assistant Director, and co-author Paul Greengrass. Wright drew on his own experiences and research into the history of the British intelligence community. Published first in Australia, the book was banned in England (but not Scotland) due to its allegations about government policy and incidents. These efforts ensured the book's notoriety, and it earned considerable profit for Wright.
