The murder that occurred early in the morning on Bolshoy Karetny shocked everyone who knew the famous photojournalist Yuri Tolchev. His young wife was also killed in his own bedroom, and Yuri himself died from a shot in the temple from a pistol that was kept in his safe. The prosecutor's version is jealousy. But the employees of the Gloria agency have a different version. And then the wife of A. B. Turetsky, who recently completed courses in forensic psychologists, gets down to business.
