Caroline Watts is a young and smart middle-class teacher who has just accepted a post as games mistress at an exclusive school for girls in the west of England. What she does not know is that her predecessor was found dead in bed from heart failure and that rumour has it she had been frightened to death. A sinister threat seems to loom over the school, possibly conjured by someone who possesses supernatural power, a "Third Eye". In spite of this atmosphere of horror, Caroline firmly believes that a rational explanation to the murder must exist and relentlessly begins her investigation… A superbly suspenseful tale and a delight for fans of Golden Age mystery genre fiction!
