The most celebrated example is the case of Rudolf #Hess, #Hitler’s deputy, who in a bizarre episode flew himself to Britain in May 1941, ostensibly to try to arrange peace talks with Britain. Concerns soon emerged about the sanity of the deputy Führer and Dr Henry Dick of the #Tavistock Clinic was engaged as part of the medical team looking after Hess under conditions of secrecy and security and with British Military Intelligence involvement. (A more popular account of the Hess internment can be found in Camp Z by Stephen McGinty (2012), including the drama of Hess’s suicide attempts.)
