Ariadna Stim. Mechanical Genius of Investigation

In Petropolis, an alternative Petersburg, after the victory of the Decembrists in 1825, the experimental robot Ariadna (police model No. 19) and Viktor Ostrovum, the only person who was not afraid to work with her, investigate crimes.

Will Viktor survive the... upcoming investigations? And who will be more dangerous for him: the city's maniacs, hired killers, or his sarcastic and self-absorbed partner?

In 1825, the Decembrists triumphed, and Petropolis struggled to recover from the bloody war.

To investigate crimes, people learned to create intelligent machines and robots. Ariadna S.T.I.M is an experienced prototype of a genius detective, but during the trials, she kills several people. The only one who wanted to work with her afterward is detective Viktor Ostrovum. He sees in Ariadna more than a ruthless machine, but where will such trust lead?
