From Massimo Carlotto's bestseller, a new type of detective story is born in Italy, closer to the American noir for the entirely new ability to elaborate and tell real experiences from the world of prison and extra-legality. "The Alligator" Marco Buratti is a former Blues singer. Unjustly sentenced to seven years in prison, as former prisoner he remained obsessed with justice. He started to use his "skills" and his knowledge of the underworld, and he becomes a very particular investigator: he feels more comfortable in the marginal and extra-legal world than among policemen and magistrates. He willingly recurs to the help of strange characters: he doesn't get his hands dirty, but he doesn't mind asking for "unconventional" help.
