Unman, Wittering and Zigo

Unman, Wittering and Zigo is a very dark thriller set in a boys boarding school where a senior form master has just been killed in a tragic accident. The main character is John Ebony, a teacher in his first job, brought in as a temporary measure, though one he hopes will be permanent. Between his rebellious wife Nadia, the eccentric art master Cary Farthingale and the class of Lower 5B, Ebony struggles to exercise power, but is thwarted by reality and a disbelieving Headmaster. Very early on in the story you find out that the previous Teacher was in fact murdered by the boys in John Ebony's class.
