I highly recommend Bill Browder book on this topic - "Red Notice: How I Became Putin's No. 1 Enemy". It's an awesome read - and very interesting. It's written by the guy who used to run the biggest investment fund in Russia and was quite an activist. Later, he and his lawyers uncovered a massive tax fraud scheme, involving a lot of important people - he became number 1 enemy there. One of the lawyers - Magnitsky, got imprisoned for several month, then beaten to death there. He (Browder) now spend his time trying to uncover more of the abuses in Russia (the recent wave of investigation into European banks is one of the fruits of his work). The book is mind boggling.
