Other times, in terms of confusion and drama of events, often resemble a kind of detective story, especially when the actions committed by historical characters fall under the category of crimes that entail the corresponding punishment. At the same time, the "investigation" of the causes of crimes sometimes stretches for centuries, which is confirmed by the works of N.I. Kostomarov's "Ruin," "Mazepa," "Mazepintsy," which make up a kind of trilogy. "Ruin" is a "troubled time" in the history of Ukraine, which soon followed the fateful Pereyaslavskaya Rada in 1654.
