El sicario (Cornerstone)

Meet El Sicario. A fugitive in the US with a $250,000 price tag on his head. He has executed hundreds of people, is an expert in torture, spent years working for the state police, and received training from the FBI. In grim and graphic detail he offers a series of confessions: Why he first became involved with the cartels and how they operate; The most effective way to torture your victim; and, The corrosive experience of looking into someone's eyes as you strangle them to death. To read this book is to enter a world of terror and corruption and to understand the man who has seen it all and, for now, lived to tell the tale.
