An Italian public prosecutor and a German police officer trying to fight human trafficking. A Nigerian woman who has been trafficked and has become a social worker, rescuing trafficked women in Italy and trying to empower girls in Nigeria so they are not lured to flee only to be trafficked. And a Nigerian mafia operating across Europe. The cast of characters in the investigative crime thriller ‘The Deal’ is bound together across laws and national borders. In an international mapping of the Nigerian underworld in Europe, “The deal” moves from Sicily to Duisburg to Nigeria, where the use of financial pressure and oaths is used to control trafficked girls and their families, who live in constant fear of reprisals. Secret recordings of phone conversations between mafia members and witness statements form the evidence in an exposé of a criminal network few knew existed.
