A young prosecutor comes to get him to join a new group in charge of investigating "delicate" cases, those that no one dares to summon: men and women of power, politics, finance, the media, the star system, lobbies, consortiums, and the bosses of large companies. Verner, a maverick with an aversion to lying, will apply his own methods.
