Sir Robert Bruce Lockhart (1887-1970) was an impressive figure: a diplomat, intelligence agent, conspirator, journalist and propagandist who played a key role in both world wars. He was a man who charmed his way into the confidences of everyone from Leon Trotsky to Anthony Eden. A man whom the influential press baron Lord Beaverbook claimed ‘could well have been prime minister’. And yet Lockhart died almost forgotten and near destitute, a Scottish footnote in the pages of history. ‘Rogue Agent’ is a biography of this gifted yet habitually flawed maverick. It chronicles his many exploits, from his time as Britain’s ‘Agent’ in Moscow, and his role in a plot to bring down the communist regime, to leading the Political Warfare Executive, a secret body responsible for disinformation and propaganda in the Second World War.
