Seicho Matsumoto's Black Gospel

Original title: 黒い福音

In 1959, a body of a flight attendant of an international airline is found, strangled. Detective Rokuro Fujisawa takes charge of the investigation with a young detective Ichimura and his investigations lead him to Father Tolbeck as a suspect. But the police are forced to move very discreetly as the time was right after the Second World War, when a sensitive situation that involves Western people and religion is likely to become an international issue. The investigation leads to an unexpected discloser of a shadowy business behind the church that reflects the uncertainty of the time.
