A Visible Darkness

New York: Minotaur Books, 2009. First edition. Hardcover. Fine/fine. Prussia has been overrun by Napoleon’s forces, and the Emperor’s troops have discovered a new source of funds there: enough amber to finance France’s wars. But their plans stall when the girls who collect the stones begin to disappear, only to be found gruesomely disfigured by an unknown killer. The French call upon Prussian investigator Hanno Stiffeniis, who must seek out the culprit knowing hat his own success may doom his country’s future. Dark, intelligent, and vividly written, A Visible Darkness continues a masterful series of historical mysteries that portray a past torn between nationalism and humanism, superstition and science."Upon finishing this third mystery featuring nineteenth-century Prussian magistrate Hanno Stiffeniis, readers are likely to give thanks for modern medicine and hygiene. As a serial killer methodically hacks and slices his (or her) way along the Amber Coast of the Baltic Sea, Gregorio takes every opportunity to supply vivid descriptions—not just of the killer’s handiwork, but also of various unpleasant anatomical inner workings. Amid the viscera, there is a crime to solve. With his wife due to deliver their fourth child and the Napoleonic Wars raging, Stiffeniis is called away to Nordcopp, where he is charged with finding the person responsible for murdering an amber collector. Unfortunately, his investigative talents, learned in Critique of Criminal Reason (2006) from no less than Immanuel Kant, cannot prevent further grisly deaths. Gregorio uses the idea of amber as a metaphor to evoke the passion of those who trade the stones as well as to suggest the evil strength and perverted intelligence of his villain, a horrifying blend of Hannibal Lecter and Joseph Mengele. Philosophy and chemistry run amok in this intelligent, compelling, but definitely difficult-to-read thriller." -- Jen Baker, Booklist Book and jacket are fine.
