The Teacher

Katerina Diamond

The Teacher is Katerina Diamond’s psychological crime debut expertly told from several different perspectives including the police, the perpetrators and the victims of a series of violent crimes. Gradually, the reader pieces the story together like a jigsaw. The truth, however, presents a number of moral complications, leaving both the characters and the reader to judge right from wrong. Adrian Miles, a detective determined to redeem himself after a suspension, is joined by Imogen Grey, a reluctant transfer from another town. They investigate the disappearance of a local business man who appears to have embezzled a large sum of money and then left the country. On closer examination, however, the detectives discover that their case is tied to a series of brutal and seemingly unconnected murders. Seven men share a terrible past which they have kept secret for over thirty years and now, one by one, they are visited and killed. It transpires that the men were engaged in ritual torture and abuse of young boys, fed to them via a well-respected private boarding school, to ‘correct’ their suspected homosexuality. The detectives eventually find themselves pulled to the museum in the heart of the city – but the museum holds more than one dark secret of its own. The story also follows Abbey, a taxidermist at the museum, both in the present and in the past when she was raped at a party at university. Scarred by her experience, Abbey is a quiet girl who enjoys working alone until the mature PhD student Parker turns up at the museum to help her in preparation for a grand reopening. The two awkward loners become close and after seeing Parker’s scarred naked body Abbey discovers a centuries-old torture room hidden within the walls of the museum. A number of pieces fall into place as she realises that Parker must be involved with the recent spate of murders in the area.
