We were provided with several copies of private letters from Xenia, and also information from her will. I'm not going to go through the evidence piece by piece as it's in the book-but certainly the Bolsheviks knew about the jewels before the murder in Ekaterinburg-that's too apparent from the wealth of information and testimonies we included. As far as Buxhoeveden's knowledge, she apparently learned it from Utkina and Nikolaieva, who also shared their information with the Bolsheviks about the jewels. Yurovsky, Kudrin, Rodzinsky, Bykov, and several others make this clear that the Ural Regional Soviet knew.
Given Buxhoeveden's pattern of behavior in Siberia after the murders-running from Sokolov rather than face questioning-I have little doubt about her role. I should add, to, that before we decided to include this information, we made quite certain that what we saw, read, and were told was correct to the extent that we could verify it. I'm sure anyone round who knew Buxhoeveden might well be horrified and label it "revisionism," but such claims stand counter to the hard evidence we saw.
