One last lesson

the long version

"University has just become a dangerous place. The body of a young woman is found on a golf course. Clues are few until Sussex Police discover she was a student, and a model on a porn website run by two of her tutors. Detective Inspector Angus Henderson was born in Fort William and while he wouldn't describe himself as a moral crusader, he abhors the fact that the owners of this website are doing nothing illegal. It's a difficult case for the DI as he is forced to face his own prejudices and to confront two animals -- but only one of them is human."--
