Unman, Wittering and Zigo

When a young man takes a vacant teaching spot at a British public school he quickly learns he may have gotten into more than he expected when upper class schoolboys threaten him with harm if he doesn't do as they wish. John Ebony has quit his job in the world of advertising and has followed his ambition to be become a teacher, moving with his wife, Silvia to a remote coastal Catholic all-boys boarding school to take up his first post. A fish out of water in the stuffy, 17th Century walls of the school, he is allotted form 5B whose previous teacher, Mr Pelham, he soon learns, fell to his death over a cliff whilst wandering too close to the edge during foggy conditions.

Undeterred, Ebony ploughs on but when one day asserting his authority by threatening to keep the class back for a Saturday afternoon detention, one of the boys informs him that the previous teacher had also once attempted this which had been the catalyst to them murdering him...
