How an Extraordinary Family Brought Down El Chapo and the Sinaloa Drug Cartel. Two women are married to the highest level drug traffickers ever to become US informants. Their husbands, twin brothers, worked with - and then brought down - El Chapo, as well as dozens of high-level members of the Mexican cartels. They had everything money could buy, but chose to give it all up when they cooperated with the US government. A love story that lifts the veil on a highly secretive world in a way no one else could.
