Stas Shamarin

Olympiada Georgievna - head librarian. About 60 years old. Pretty, friendly, emotional. Black dyed hair down to the middle of her neck; swamp-green eyes; glasses with several facets on the frame; a small dog named Virginia.

Stas is 21 years old. Light brown hair, parted mostly on one side, the rest on the other, fairly short. He has swamp-green eyes and is tall and thin. He's a comedian, quite calm, and almost the complete opposite of Nikita in terms of personality: straightforward, sometimes even too straightforward.

Investigator Glikerya Vasilyevna Davydova, 28 years old. Long, light brown hair pulled back into a ponytail. Plump, not very tall, blue eyes, pretty, but actually a near-brilliant investigator, with a remarkable record of solving the most complex murder cases. She likes Daniil.

Daniil Andreevich Talich, 29, has curly dark hair down to his ears, a mustache but no beard, and is thin and tall with blue eyes. He may be in love with investigator Glikeria (Lika), whose education and regular encounters with the police have led to him being like family there.
