MASK: MI5's PENETRATION OF THE COMMUNIST
PARTY OF GREAT BRITAIN
by
Nigel West
An account of
the British Security Service's dramatic interception of
secret signals to Moscow from a hidden base in London
uncovered the true extent of Soviet espionage in Britain.
Intelligence expert Nigel West reveals how MASK, the
codename for one of the most secretive sources ever run by
British intelligence, enabled the British Government to
monitor the activities of the Communist Party of Great
Britain and track wireless traffic between the Soviet Union
and its Comintern representatives abroad during the mid
1930's. The Government Code and Cipher School was one of the
most secret branches of Whitehall, under the command of the
Secret Intelligence Service, and used its covert intercept
station in South London to make vital advances in the
intelligence war. This gripping account exposes for the
first time how the Communist Party of Great Britain was
infiltrated and details the actual contents of its
communications with the Soviet Union.
