Oh, and there's some gossiping about two women writing letters to Voltaire and Voltaire possibly answering. (Fritz needs to know everything of course.)

LOL. Of course!

Preuss definitely left out some of hers, no idea if he also skipped some of Fritz's.)

Well, the only editions where I can contrast and compare is Fritz/Wilhelmine with Preuss versus Volz versus "So lange wir zu zweit sind", and Preuss definitely left out some (especially of Wilhelmine) which Volz has, so it wouldn't be surprising if he did the same with the Camas letters. As for excerpts, please do. I'm currently way too busy to read and review.

OH, and btw, cahn: Countess Camas is the old lady depicted in Menzel's Flute Concert at Sanssouci painting, and the one one delivering the punchline in Lehndorff's Wartensleben the sugar horder write-up. Lehndorff also mentions her greeted and hugged by Fritz upon his return post 7 Years War (as opposed to poor EC). Her being called "Maman" is telling in itself.
