From the description:
"Facing his demons in his first year of sobriety, Matthew Scudder finds himself on the trail of a killer. When Scudder's childhood friend Jack Ellery is murdered, presumably while attempting to atone for past sins, Scudder reluctantly begins his own investigation, with just one lead: Ellery's Alcoholics Anonymous list of people he wronged. One of them may be a killer, but that's not necessarily Scudder's greatest danger. Immersing himself in Ellery's world may lead him right back to the bar stool."
