Oh WOW! That is a great find!

I mean, you know I am a Fredersdorf stan, but still I claim Fredersdorf was not insecure or murderous enough to arrange for Georgii's death :P Here are my arguments:
-You pointed out that Fredersdorf was gracious to people below him like Lehndorff, even when he was ill and not his best. That doesn't strike me as a quality of someone who would get rid of a person who was giving him trouble
-Blanning tells me that Fritz bought Fredersdorf an estate immediately after ascending to the throne; do we have a date on this and how does it compare to the date of Georgii? I guess if it was after Georgii then maybe this is evidence against, lol

- or, if Georgii the handsome soldier really did commit suicide: maybe gossip has reversed cause and effect here, and Georgii offed himself after realising he was just a fling and Fritz had no intention of letting him replace Frederdorf?

This makes much more sense to me :P Although, okay, I guess I also would buy mildred_of_midgard's theory of blackmail, I mean, I think Fredersdorf is nice enough not to arrange for someone's murder but I think it's very possible he might go for finding out dirt on someone and letting events play out :P
