That’s strike one.
The story has a great plot element about a missing manuscript dating back to the Italian Renaissance. The murder victim, Bruce Lombardi, had been working on translating the text and had discovered all sorts of ties to witchcraft and black magic and the death cult of the Borgias. Does the motive behind the murder have anything to do with this intriguing, possibly dangerous manuscript? No. It’s all incidental background.
That’s strike two.
The book is narrated by Robert Kintyre, professor of Renaissance history and expert on Machiavelli. When his graduate student/teaching assistant is found brutally murdered and bearing wounds that indicate gruesome torture Kintyre turns sleuth and does his best to get to the bottom of the puzzling crime. But in his amateurish imitation of a badass crimefighter he endangers the lives of others and is directly responsible for a second murder that seems gratuitous and senseless even within the confines of this insular academic community. Kintyre keeps thinking he should tell the police what he knows but suffers from the Hamlet syndrome of deliberating and meditating too much on his thoughts and never acting on them. I have no problem telling you that the villains turn out to be involved in a drug operation and the real culprit had hired a bunch of thugs to do all his dirty work. Shades of pulp fiction master criminals? No, instead it’s wholly contrived for the sake of a twist in the final pages.
