Eyewitness testimony is notoriously unreliable. Even more so when Kinsey Millhone's only lead is a grown man dredging up a repressed childhood memory-of something that may never have happened... "Expect to be spellbound." "Has this reliable series lost its addictive appeal? Not at all." "Makes me wish there were more than 26 letters at her disposal." New York Times bestselling author Sue Grafton is published in 28 countries and 26 languages—including Estonian, Bulgarian, and Indonesian. Books in her alphabet series, begun in 1982, are international bestsellers with readership in the millions. And like Raymond Chandler, Ross Macdonald, Robert Parker, and John D. MacDonald—the best of her breed—Sue Grafton has earned new respect for the mystery form. Her readers appreciate her buoyant style, her eye for detail, her deft hand with character, her acute social observances, and her abundant storytelling talents. Sue divides her time between Montecito, California and Louisville, Kentucky, where she was born and raised. She has three children and two grandchildren. Grafton has been married to Steve Humphrey for more than twenty years. She loves cats, gardens, and good cuisine.
