Fighting novels about the daily feat of Soviet front-line military intelligence officers. A duel of strength and spirit when the enemy’s front line is only a few steps away. Details of brutal battles that even veterans—participants in those events—don’t talk about. After treatment in a hospital, Captain Gleb Shubin returns to his unit. On the way, he becomes a witness to an air battle: a Soviet aircraft is attacked by three German fighter planes. As a result of this unequal fight, our plane is shot down. The pilot manages to jump out with a parachute and land somewhere on a neutral strip. Shubin reports what he saw to the command. It turns out to be our aerial reconnaissance aircraft returning from a mission with particularly valuable information about the enemy’s defenses. The captain is ordered to urgently find the pilot and deliver him to headquarters. Shubin, with a group of fighters, sets off on the assignment—without yet knowing that on the other side, the best German spies have already begun hunting that valuable ace… The author’s total print run is over 10 million copies.
