Prequel to the Inspector De Luca quartet.

In November 1944, in the worst winter ever known in Bologna, in the depths of the war, the bomb-scarred streets are home to starving refugees who have fled the advancing Allies. The Fascist Black Brigades, the officers of the S.S. and the partisans of the Italian Resistance compete for control of the city streets in bloody skirmishes.

Comandante De Luca, who has proved himself “the most brilliant investigator” in Bologna, but who is now unwillingly working for the Political Police in a building that doubles as a torture facility, finds himself in trouble when three murders land on his desk: a professor shot through the eye, an engineer beaten to death, and a German corporal left to be gnawed on by rats in a flooded cellar.

De Luca must rapidly unravel all three cases with ten lives on the line: ten Italian hostages who will face a Nazi firing squad if the corporal’s killing is not solved to the German command’s satisfaction.

As he navigates a web of personal and political motivations – his life increasingly at risk – De Luca will not stop until he has uncovered the dangerous secrets concealed in the frozen heart of his city.
