The Golden Key is the second book in the trilogy by Mikhail Kharitonov. It continues the story of Buratina and his adventures with the troop of Karabass. The book is thick and smart, full of sex and cruelty, which serve only as mood setters. The author has made the world of this book much more solid and added more questions. There are several layers of narrative, which may be traced only in footnotes, and those footnotes are an important part of this book. If you've read the first book, you definitely need to read this one too.
