About the book: 1970 / From the preface:...The plot of the story is adventure. A certain adventurer persistently and ingeniously searches for a rare “Assyrian manuscript” in the collections known to him, which the British Museum is ready to buy for a lot of money... “The Encrypted Plan” is a typical adventure story. It has everything: mystery, search, pursuit, unexpected moves and exits......If you re-read all these “stories about gold”, ...then it’s not difficult to notice that in essence we are dealing with separate chapters one big story...N.
