Too Secret Too Long
By Chapman Pincher.
Description
The most powerful, infuriating, heartbreaking book ever published about spies . The man, Roger Hollis, worked in British Intelligence for 27 years, and for nine of them he was head of M15-which meant he was Britain's equivalent of J. Edgar Hoover. The woman, known as Sonia, was a Soviet master-agent for decades-and she still alive. - from Amzon
