Between 1938 and 1948, from the height of Italys Fascist regime to the end of the tumultuous post-war period, Chief Detective De Luca investigates and solves crimes in the City of Bologna and along the Adriatic coast. With little or no regard for those in power, whoever they happen to be, his solitary, uncompromising character often lands him in trouble, but his respect is reserved for truth and justice alone. In the four TV movies of the series Unauthorised Investigation, Carte Blanche, Murky Summer and Goose Way - each taken from a novel by best-selling mystery writer Carlo Lucarelli Chief Detective De Luca always ultimately gets to the bottom of his cases, though what he finds often leaves a bitter aftertaste.
