YA-Asked to investigate the death of 25-year-old Lorna Kepler, which occurred 10 months earlier, P.I. Kinsey Millhone uncovers the young woman's secret life as a high-class call girl, her half a million dollars in blue-chip investments, but no clue as to the murderer. The main plot is strengthened by several subplots including the whereabouts of a $20,000 withdrawal made the day of Lorna's death; the misleading spying antics of her landlord's wife; and the greed and jealousy of the victim's overweight older sister. Grafton's writing is vivid when describing Kinsey's soul-searching about the evil some people commit and in the resultant powerful ending. Though the 11th in the series, "K" is neither weak nor repetitive, providing excitement, intrigue, and a fierce need to finish reading it in one sitting.
