In the third book of the series, we’ll get a continuation of the story of Agasfer, who was sent earlier to Sakhalin. The Russo-Japanese War has begun. At the same time, another war is flaring up—one invisible to the uninitiated. Lavrov’s reconnaissance unit is trying to be pushed off the “battlefield”; the agents conducting surveillance notice that someone is watching them, too. Urgently, the situation must be brought back under control and it must be clarified who is the enemy and who is one’s own.
