Major Igor Thunder. Book 4. Somewhere under Peter. Kutuzov K.S., Eronin E.

In St. Petersburg, a new impudent robbery takes place: a gang of people in pioneering uniforms, led by the Kiborg criminus, attacks the social event of the city elite. It would seem that this is an ideal thing for Igor Grom returning to the police! However, the major is taken for a completely different investigation: someone stoles the old signs from the houses, which constitute the historical appearance of Peter. This business first does not seem so important and dangerous until it turns out that it is directly related to the “pioneer” - and behind everything there are old enemies of thunder from a completely different life.
