Biology Ph.D. candidate Marie Skov is devastated when, on the same day as her mother's death, her mentor Kristian Storm apparently kills himself. Storm had been facing academic dishonesty charges, as well as heated criticism of his research on a vaccine for African children--that suggested the vaccine was causing more harm than it was preventing. Skov is skeptical that the death was a suicide. She knows Storm's research on the vaccine was sound, and learns that his on-site work in Guinea-Bissau was marred by intimidation, sabotaged data, and the suspicious death of another scientist. She also learns that in his final days, Storm felt he was being followed by a blue Ford with tinted windows. Soon afterward, a blue Ford with tinted windows parks across from Skov's home. The police have no interest in re-examining the official narrative. But Marhauge shares Skov's desire for answers, and defies his superiors to help her investigate. They receive unlikely help from a Nobel Prize-winning rival of Storm's, and find themselves on a perilous trail that leads to Big Pharma and the World Health Organization.
