One of the teachers at an all girls English public school is murdered and all the staff are suspectsto the policeman who comes in to investigate. The story is partly told from the view of the obvious suspect who is the teacher who is also being the amateur sleuth (Barbara Murray). There is nothing great about tthe plot, though there is a solid performance from Gordon Jackson with support from Sam Kydd as his assistant.
