Education, Education, Murder!

A break in, a robbery and a hideous murder at a local primary school.
This is a vicious and unusual event in the dreary mill town of Telbury where Detective Inspector Marcus Harrison finds himself after transferring against his will from the big city. At least now he has a case to get his teeth into that will take his mind off his own troubles.
But is it such a simple case?
Surely these events are related, aren’t they?
With such an unpopular victim, suspiciously behaving staff, blackmail, corruption and vice all being uncovered, finding the murderer may be trickier than he thought.
If working through these issues wasn’t enough, the discovery of a second body throws all reasoning out of the window.
Only with help from an unexpected source can DI Harrison bring the killer to justice.
