Flag, Drum and Locomotive

The ability of Linka Sinitsina, the close friend of Evdokiya Zemleroyeva, to fall in love with anyone usually did not cause Dusya much inconvenience. All of Linka's infatuations Dusya classified as hopeless losers, but the new suitor was nothing like... a failure; he was extraordinarily good-looking. Dusya didn't even feel too stressed when Sergey invited the girls to take a trip to N­sk, where he had some business. She let her friend go with a light heart, but categorically refused to go herself. The last major investigation of private detective Zemleroyeva was connected to this city, and after it, Dusya became an unwitting bearer of deadly dangerous compromising material. No way, she wouldn't step foot in N­sk now... When a few days later her friend stopped getting in touch, she realized with horror in her heart: carefree Linka was in captivity, and it would be up to Dusya to rescue her.
