A hit man stalks his mark at a race track. A sociopath crosses every moral boundary to become a published author. An ex-mercenary obsessively defends his "perimeter" from a dangerous interloper. A man for hire grudgingly accepts help from a teenage girl to track an online predator. In a dystopian future, young people struggle for survival underground, forming themselves into vicious gangs with only the graffiti of the "last journalists" accepted as truth. Andrew Vachss collects twenty tight, powerful stories--all from the past decade of his career, including some now published for the first time--along with an original screenplay. Together, they form Mortal Lock, a searing portrait of the criminal underworld, with both its depravity and humanity on display.
