Miss X

Before the Second World War, Britain's Security Service was concerned that foreign spies were operating across the country, collecting military and economic intelligence and passing it on to the enemy. There were worries that some people were stealing and selling state secrets. In order to collect the evidence needed to convict people of spying for the enemy, the Security Service employed agents to go undercover, sometimes for years. One such 'mole' was a woman whose 'handler' only referred to her as 'Miss X' or Moses. Her real identity was not revealed until decades later. What had been a TOP SECRET file was not released by the British Government until January 2025. Bernard O'Connor has researched her story and brings to light the correspondence between 'Miss X' and her 'handler' for the first time.
