A girl was brutally murdered on the main avenue of the capital of the Russian Empire. The Emperor was informed of this a few hours later, during the midday report. “I would like to see this murder solved as soon as possible!” - such is the command. And police officials flashed along Nevsky, Znamenskaya, Italianskaya, Bolotnaya... St. Petersburg newspapers were full of terrible headlines. The master of the Russian legal profession, Karabchevsky, began to find out the truth. His assistant Shumilov does not hesitate to go down to the most terrible depths of the city - taverns on Ligovka, and starts shooting in broad daylight... They are all looking. Some are a murderer, others are a means to quickly and easily carry out the highest command. All events actually took place in St. Petersburg in 1883.
