Pied Piper

Yegor Bulatov moved to a new job after the death of his best friend and workmate Nikolai Karpenko, who, according to Yegor's assumption, died through the fault of one of his own. Constantly tormenting conscience and desire to find a "rat" help him become the best investigators. Bulatov's own investigation now and then comes to a standstill, but unknown messages about a friend do not allow him to quit what he started.
