Hello Romanov Fan
I agree with all the historical points already made. It's worth, I think, having a particular look at Boris's III of Bulgaria, who did find himself dealing personally with Hitler, and actually suffered his fatal heart attack while flying back from one of their meetings. From all I know of Boris's, he was a very decent man and so must have been completely out of sympathy with him on a personal level, which would give you some useful insights. Unfortunately, there's not a huge amount written about Boris's in English.
Also worth looking at Michael of Roumania, who was in a similar position, with the extra difficulty of being very young and having just emerged from a pro-German regency.
Hope that helps. I didn't dare use a real person as my central character!
I see an adult Alexei limping heavily after the crisis at Tobolsk. Is this going to colour his attitude to the armed forces?
Incidentally, everybody, would you like to see some more of Sandor Dolgoruky and Kate?
