Half Moon Street rape-murder and student
A butcher's daughter is found strangled in her room, and her father accuses the poor student she had been secretly admitting at night, who has already been convicted in principle by the previous magistrate. Judge Dee finds that the girl's secret signal and access route had been noticed by an outsider, a vagrant, who entered in the student's place. The student is freed: the obvious suspect was the man with a known motive and presence, not the one who committed the act.
