Unexpectedly for everyone, the vice-president of the joint-stock company "Gems", which supplies costume jewelry and semi-precious stones abroad, commits suicide. A large batch of large emeralds from one of the Ural deposits was found in his apartment, as well as a suicide note in which the culprit of death was named... Nikita Orel, a tax police officer.

Was it really suicide? How to explain the close and secret cooperation of the modest “Gems” with the large German jewelry company Richter Edelstein?

Nikita Orel’s task is to find answers to all questions, drop charges and get on the trail of the real criminals.
