Book excerpt: 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. In a novel widely celebrated by critics and readers, Lawrence Block circle back to how it all began, reestablishing the Matthew Scudder series as one of the pinnacles of American detective fiction. "Right up there with Mr. Block's best . . . A Drop of Hard Stuff keeps us guessing." -- Tom Nolan, Wall Street Journal
