November 21 Himmler announced to the public that the assassination plot against Hitler at the Buergerbraukeller had been solved. It was done at the instigation of the British Intelligence Service, two of whose leaders, Stevens and Best, had been arrested on the Dutch-German frontier on the day following the bombing. The actual perpetrator was given as Georg Elser, a German Communist carpenter residing in Munich.
Himmlers detailed account of the crime sounded fishy to me, as I wrote in my diary the same day. But his accomplishment was very real. What Himmler and his gang are up to, obviously, I jotted down, is to convince the gullible German people that the British government tried to win the war by murdering Hitler and his chief aides.
