The final novel of the trilogy "The Provincial Detective, or the Adventures of Sister Pelagia". On the steamer "Sevryuga", sailing along the Volga, a terribly motley company gathered in an absolutely incredible way. Here are the Doukhobor sectarians fleeing oppression to Canada. And Jewish pilgrims to the holy land. And a family of sodomites sailing into the newly created new Sodom. And the "foundlings" are Russians who converted to Judaism. And even the mysterious and mysterious "Christ guardsmen", which no one has seen, but everyone knows that they are definitely on the ship. To this set, in addition, you still need to add a thief named Gingerbread Man. Is it any wonder that this "powder mixture" sooner or later "explodes". And one by one, the dead begin to appear ... But a small group of passengers from Zavolzhsk is also sailing on the Sevryuga, among which is the nun Pelagia.
