KGB Headquarters

Polished furniture, portraits of Lenin and Khrushchev on the walls, and shelves full of books about the war. The air is filled with the scent of strong tobacco mixed with the pungent smell of gunpowder. A military tunic is carelessly thrown onto a chair. Its owner is meticulously writing something on paper at a table. He then loads a pistol, opens his hiding place, and carefully places the weapon with the note inside. Before this, he performs many strange manipulations. The colonel does not want his secret to be revealed after his death. Your task is to unravel the mystery that the military man has been hiding for many years.
