Even the Wicked (Matthew Scudder #13)

Matthew Scudder knows that justice is an elusive commodity in the big city, where a harmless man can be shot dead in a public place criminals fly free through holes in a tattered legal system. But now a vigilante is roaming among the millions, executing those he fees deserve to die. He calls himself "The Will of the People"—an ingenious serial killer who announces his specific murderous intentions to the media before carrying through on his threats. A child molester, a Mafia don, a violent anti-abortionist—even the protected and untouchable are being ruthlessly erased by New York's latest celebrity avenger.
