The matchless detective and psychoanalyst Mrs Bradley is visiting the picturesque village of Spey in search of a local witch when Gerald Conway, a junior master at Spey College, is found murdered. Despised by both pupils and peers, there is no shortage of suspects but can the redoubtable Mrs Bradley use tact, wit and just a touch of black magic to make the boys and their masters divulge the truth?
