"By this time [September 1938] it was clear to me that Hitler was bent on having his little war. I felt that the interview could have little result and Hitler's behaviour was so offensive that I wanted never to see him again. He seemed to be enveloped in an aura of such ruthless wickedness that it was oppressive and almost nightmarish to sit in the same room. I therefore asked Wilson if I might be excused from attending. This was very pusillanimous since the interviews were certainly interesting and exciting enough for the most blasé of officials. I can only say that Hitler had inspired me with such a physical repugnance that I could not bring myself to go."
