When a pupil accuses a teacher of molesting her, his career and marriage are threatened... The girl's corpse is discovered in the woods, and the teacher becomes a suspect in a murder enquiry. The victim's best friend is then murdered so she cannot reveal the killer's identity. The investigating team are satisfied the teacher is guilty, apart from Detective Inspector Geraldine Steel, who believes the wrong man has been arrested. All of her colleagues disagree... but if she is right, the real killer remains at large.
