“Bestseller” is a harmonious fusion of an excellently developed plot and extraordinary stylistic skill. At the center of the novel is the figure of the famous Vladimir Burtsev, who at the beginning of the last century earned the formidable nickname “hunter of provocateurs,” and among the heroes are Lenin, Stalin, Azef, Malinovsky, agents of the tsarist secret police and professional revolutionaries. Who will become the target for the “hunter” in his struggle for the moral purity of the ranks of the “coming reformers of Russia”? And what is the general phenomenon of betrayal both for an individual and for the country as a whole?
