Analysis of information sources in references of the Wikipedia article "Prince George, Duke of Kent" in English language version.
... probably the strangest book ever written on the Hess affair is Double Standards... The thesis of Double Standards is that Rudolf Hess ... died in the plane crash in northern Scotland in August 1942 which also killed the Duke of Kent ... Hess was being transported to neutral Sweden (not Iceland, given in the official story as the plane's destination) to be handed over to the Germans as the first step in a settlement of the war between Britain and Germany. ... Double Standards seems breathtaking in its implausible inaccuracy.
