In a quiet, small Czech village, a gruesome murder shatters the peace when the brutally murdered body of a girl is found inside the village's only church. Initially, investigators suspect satanic rituals are behind the crime, but the threads of the investigation uncover mysterious secrets that lead them to a complex web of relationships between the priest, a university professor specializing in ornithology, and an eccentric religious expert who believes the priest is an exorcist of evil spirits. When a new, more violent crime occurs, it becomes clear that what happened was merely the beginning of a series of horrific events that threaten to expose the hidden truths of the entire community. With a style that combines thrilling detective work and deep psychological analysis, Michal Sikora presents a captivating novel that reveals the conflict between science and superstition, truth and illusion, and the desire to uncover the perpetrator versus the fear that the truth might be more terrifying than the crime itself.
