hi. i managed the first book and opened the tin thing but now im on the book out of the briefcase and i'm stuck on 2 of the puzzles. i did the one about the submarine, but im stuck on the significance of ekaterinburg on the chess puzzle and i can't find a lake name that works for the sundown one.
please help!
I see pega has made life easy for you, but if you entered into the search bar 'history of Ekaterinburg' and looked at 1960 you would have found the answer.
