Two old friends were killed, one of whom was the deputy head of the Internal Affairs Directorate at the Moscow Metro, the other was an artist who devoted himself to an unusual form of art - graffiti, street painting. Why did these two end up in a deserted place at such a late hour? Do the explosions that recently occurred in the subway have anything to do with this murder? Or maybe the double murder is just a family matter? All this will have to be sorted out by Senior Assistant to the Prosecutor General Alexander Borisovich Turetsky, who heads the investigation team.
