When the body of a radical protestor is found floating in one of Bologna's underground canals, it seems that most of the city is ready to blame the usual suspects: the police. But when private investigator Daniel Leicester, son-in-law to the former chief of police, receives a call from the dead man's lover, he follows a trail that begins in the 1970s and leads all the way to the rotten heart of the present-day political establishment. Beneath the beauty of the city, Bologna has a dark underside, and English detective Daniel must unravel a web of secrets, deceit and corruption - before he is caught in it himself.
