W is for Wasted by Sue Grafton

Kinsey is puzzled when she gets a call from the coroner's office asking if she could come and identify a male body that had her name and phone number in his pocket. After she sees the deceased, Kinsey is even more perplexed, because she's never met the man, who was homeless. Not having any current cases, she decides to determine the man's identity. Soon, she finds out his name was Terrence Dace and realizes that several months ago someone had called her office asking about him. What is Terrence's connection with Kinsey? Kinsey also finds herself pulled into an investigation of the dealings of shady fellow private investigator Pete Wolinsky after his murder. In W is for Wasted, Grafton has presented the reader with an interesting puzzle, along with some introspection on Kinsey's part--which makes perfect sense, since there are only a few books left in the series.
