The Sins of the Fathers by Lawrence Block

Slow plot, but Lawrence's characters are so interestingly normal. PW: Block has been getting better and better in recent Matt Scudder novels, but as this first hardcover version of a 16-year-old paperback shows, he was pretty good from the start. King's admiring introduction is generous but by no means overstated. This tale, which introduced the then-hard-drinking ex-cop, is spare and lean and full of dark insights into lonesomeness and anguish. The father of murdered Wendy Hanniford comes to Scudder to try to find out more about his errant daughter--not to find her killer, who was apparently her living partner, a brittle young man who was found in the street raving and covered with her blood and who killed himself shortly after he was arrested. In his dour, methodical, oddly empathetic way, Scudder finds out a great deal, altering several lives in the process.
