:

Kabanov and Vorontsova finish the investigation in Kondopoga and return to St. Petersburg. The boss is pleased with them, but insists on closing the case: once a maniac is in a hospital, further ones are useless. But investigators believe that they must continue, because the murderer of Livanova has not yet been found. The partners are sure: Kovalevsky himself dealt with it.
