Sue Grafton ups the ante for private investigator Kinsey Millhone like never before in this “taut, terrifying, transfixing”* #1 New York Times bestselling mystery in the Alphabet series. Kinsey Millhone's elderly neighbor, Gus Vronsky, may have been the original inspiration for the term “Grumpy Gus.” A miser and a hoarder, Gus is so crotchety that after he takes a bad fall, his only living relative is anxious to find someone to take care of him and get back home as soon as she can. To help, Kinsey runs a check on the applicant, Solana Rojas. Social security, driver's license, nursing certification: It all checks out. And it sounds like she did a good job for her former employers. So Kinsey gives her the thumbs-up, figuring Gus will be the ideal assignment for this diligent, experienced caregiver. And the real Solana Rojas was indeed an excellent caregiver. But the woman who has stolen her identity is not, and for her, Gus will be the ideal victim... “The best and strongest book in the series...Solana is one of the most evil, calculating characters Grafton has created.”—*USA Today
