Hubertus Lowenstein KV2/3716

This Austro-German prince left Germany for Britain when Hitler came to power. An active, if eccentric, anti-Nazi anxious to build a Germany free from National Socialism, his personal ambition was said to be no less than the German throne. He moved to the USA in 1939 from where, during the war, he was in contact with Jurgen Kuczynski, the Soviet agent who introduced Klaus Fuchs to espionage, though no incriminating construction was put on their relationship. The file describes Lowenstein as being 'snobbish', 'dangerous' and having 'sensations of unreality'. In 1934 he wrote a book entitled 'The Tragedy of a Nation'.

Father Henry Borynski KV2/3724

Borynski served as a priest in a largely Polish parish in Bradford in the early 1950s. He replaced a Lithuanian/Pole with a dubious reputation; and Borynski's sudden and unexplained disappearance in 1953 initially suggested possible complicity in his removal between his predecessor and Polish Intelligence. The case received very wide national publicity with speculation he had been 'kidnapped by Red Agents and taken behind the Iron Curtain'. There was a popular belief in the Polish community that he did not disappear of his own free will. MI5 were marginally involved in the investigation which has never been solved. Possible theories listed in the file include that he may have been on a secret mission, he was a Polish agent, he was murdered or kidnapped, or that he was involved in a scandal. Over the years, the file notes several alleged sightings of Borynski and letters pertaining to be from him. A professional Soviet assassin later confessed to murdering him 'with an injection of cyanide' and then burying his body after being 'forced to act under orders from the highest soviet authorities.' But it was thought this account may have been made up by a local newspaper.

The files range from KV 2/3722 to KV 2/3724
