Had a few late nights finishing this great thriller: Critique of Criminal Reason by Michael Gregorio.
It was the perfect book to curl up in bed and read.
Darkly atmospheric it conjured up Prussia in the 1800s wonderfully. Set in Konigsberg in 1804,the book follows the hunt for a serial killer.
Adding a real historical flavour to the story is the fact that the young magistrate/hero of the story, Hanno Steffinis, is mentored by aging philosopher Immanual Kant.
I'm not too au fait with philosophy, having dropped it as a subject in first year uni, the book got me interested in Kant's ideas.
A thoroughly enjoyable and gripping read. I'm looking forward to getting my hands on the sequel - Days of Atonement.
