A repentina chegada de Rudolph Hess na Escócia causou grandes desconfianças na Rússia, fazendo-os indagar sobre a possibilidade de um pacto entre a Inglaterra e a Alemanha para invadir a Rússia. Abaixo, Churchill descreve uma conversa que teve com Stalin, três anos depois da chegada de Hess.
Considering how closely Hess was knit to Hitler, it is surprising that he did not know of, or that if he knew he did not disclose, the impeding attack on Russia, for which such vast preparations were being made. The Soviet Government were deeply intrigued by the Hess episode, and they wove many distorted theories around it. Three years late when I was in Moscow on my second visit I realised the fascination which this topic had for Stalin. He asked me at the dinner table what was the truth about the Hess mission. I said shortly what I have written here. I had the feeling that he believed there had been some deep negotiation or plot for Germany and Britain to act together in the invasion of Russia which had miscarried. Remembering what a wise man he is, I was surprised to find him silly in this point. When the interpreter made it plain that he did not believe what I said, I replied through my interpreter, "When I make a statement of facts within my knowledge I expected it to be accepted." Stalin receveid this somewhat abrupt responde with a genial grin. "There are lots of things that happen even here in Russia which our Secret Service do not necessarily tell me about." I let it go at that.
