Literature professor Jack Griffen has recently suffered a nervous breakdown. His wife has divorced him and she and their adult daughter have moved to the USA. Into the void steps exchange student Hieronymus Beck, claiming to be the professor’s greatest fan.

His student has told him he’s writing a crime novel, but is that all he is doing? Caught up in his protégé’s dangerous game, the mild-mannered professor finds himself asking how far will he go to save a life. As far as murder?
