When Martha arrives at her weekly appointment at the neighborhood beauty salon, her hairdresser, Betty, is amazed to see her black hair has gone white. What has happened? Did Martha try to dye her own hair? The secret, it seems, is that Martha has a grandson named Joe, and Joe has a pet mouse named Delmar. As Martha tells her story to Betty, the hairdresser continues to cut Martha's hair. But she isn't paying very close attention to what she's doing. What will happen to Martha's brand-new white hair? In this children's book, one woman's new hairdo goes from bad to worse as she recounts the story of how her hair changed from black to white.
