The reader is invited to the novel “In Search of the Murderer” (1915). This is book I of the “Old Criminal Novel” series. The author of the book, A. E. Zarin (1863–1929), is a prose writer and journalist, a master of the criminal novel at the turn of the 19th–20th centuries. To modern readers he is better known for his historical works. But it was the crime genre that made Zarina’s name in Russian literature. In the case of a dismembered female corpse, St. Petersburg detective Patmosov has a personal interest. The name of the criminal is known; a meticulous detective and an imperturbable psychoanalyst can expose him. But you must be able to maintain restraint, understanding that the life of a beautiful lady hangs by a thread.
