What she discovers leads her into the past where an unsolved crime was committed. The book is illustrated by Ray Grass, with photographs by Betty Perkins.
The Book with the Broken Locket continues Perry's adventures, as she becomes intrigued by a local case that comes to light when she finds a copy of Nancy Drew's The Clue of the Broken Locket from the late 1930's. As she explores the marginalia written in this book, she learns of the untimely and secretive death of a local girl, and she must discover the mystery of her life and death. The book is illustrated throughout by Ray Grass.
The Book with the Good Intentions takes Perry in a very different direction than her previous two cases, as she delves into the lives of people still living. When she finds a marked-up copy of Ogden Nash's Good Intentions in a thrift store, she goes down a dark and somewhat dangerous road to find a woman whose life took a wrong turn.
