cast gives High Treason a high polish," concluding that the film is "a taut tale and a pleasure". In 2013, a contributor to Cageyfilms.com wrote, "although the politics of High Treason are as dated as those of Leo McCarey's My Son John (1952), the location shooting in London and the character details around the periphery of the narrative provide a fascinating documentary portrait of the metropolis just a few years after the war and, as in Sam Fuller's Pickup on South Street, the ostensible political element can be seen as little more than a MacGuffin on which to hang the narrative. And speaking of MacGuffins, the film has several very well-developed Hitchcockian elements, particularly the pretentious modern music society which serves as a front for the communist plotters and the labyrinthine building which doubles as a tutorial college and secret commie headquarters".
