Secret fight. Matveev G.

The second book of the Tarantula trilogy. In the fall of 1942, the besieged Leningrad was subjected to bombing and systematic fierce artillery shelling. The enemy was preparing for the assault on the city. But in addition to an external threat, there was an internal one: the city operated in the city of fascist spies and saboteurs. Leningrad boys, familiar to readers from the first novel by the Green Classes trilogy, helped to find and neutralize their counterintelligence.
