What this book is about

In 1988, a young man named Michael Sutton approaches Kinsey Millhone with a memory: as a child in 1967, he saw two men burying something in the hills. He believes it was the body of a kidnapped girl whose case was never solved. Kinsey investigates in parallel narratives — one in the present, one unraveling the 1967 events — in one of Grafton's most structurally ambitious alphabet mysteries.
