Blurb

Critique of Criminal Reason is an English language crime novel written by Michael Gregorio, the pseudonym of Michael G. Jacob and Daniela De Gregorio, two scholars teaching in Spoleto, central Italy. It is set in Königsberg, during the height of Napoleonic wars, in 1804.
It details the attempts of a young Prussian magistrate, named Hanno Stiffeniis, to catch a murderer who has committed a series of grotesque and unsettling murders in the city. He is aided in the task by a sergeant of the local police, Herr Köch, and together they create a pair of heroes slightly reminiscent of the Sherlock Holmes and Dr. Watson tandem. Of note is the historical character of Immanuel Kant, who also takes an important part in the investigation.
The novel is the first of a series of novels illustrating Hanno Stiffeniis' exploits. It was followed by Days of Atonement, A Visible Darkness and Unholy Awakening.
