Continuation of the retro-detective stories about Yakov Rovner

Proskuriv, Medzhybizh, Letychiv, Novyi Kostiantyniv. 1912.

Twelve years have passed since the last case in Kamianets. And Jacob Rovner once again finds himself in the midst of mysterious events. An ordinary Sunday evening service in a village church ends with an incomprehensible event: a streak of bright light crosses the sky and disappears in a few minutes. Should we believe in a miracle of God or in Austrian spies? Should we write it off as a weather whim or should we listen to the old Hasidic stories? And how can we connect the eerie light with the graves of Ustym Karmeliuk and the semi-legendary Hasidic philosopher Ba'al Shem Tov? So many theories and so few answers to satisfy the inquisitive mind of the Proskuriv surgeon. Yakov Rovner embarks on another investigation, during which he may become a criminal himself.
