Death of a Codebreaker - A new BBC Radio Wales investigative series exploring the death of the codebreaker and mathematician Gareth Williams, who was found dead in a zipped up suitcase in his flat in central London in 2010.
Was his death the result of his own complicated private life, or was a ‘third party,’ such as agents linked to the Russian state, responsible? Dr Sian Williams and Dyfan Rees chart the events throughout his life. They also explore the work of GCHQ, MI6 and the intelligence services and the rise of Russian organised crime within the city at that time. Six episodes are available to listen to now.
