by Paula Longhurst
V. I. Warshawski (or Vic to her friends) is drawn into the investigation of a missing meth addict and her genius son. Vic’s longtime friend Dr. Lotty Herschel shares a past with the missing woman’s grandmother. What seems like a simple addict-on-the-run case turns complicated as Vic uncovers connections between the great-grandmother and a Nobel-winning Austrian scientist who worked on the Manhattan project. And her investigation is ruffling some pretty high-level feathers . . .
