Spycatcher: The Candid Autobiography of a Senior Intelligence Officer (1987) is a memoir written by Peter Wright, former MI5 officer and Assistant Director, and co-author Paul Greengrass. He 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.In 2021 and 2023, the Cabinet Office was still blocking or redacting freedom of information requests for files on the Spycatcher affair despite the rule that documents should be released after 30 years.
