Dr. Kep Woodhead is a brilliant, irascible forensic toxicologist with a dark past. Bernadette Becker is a disgraced federal investigator with one last chance. They're both assigned to a strange poisoning case: a graduate student has been found dead in a 15th-century chapel, a needle filled with a controversial hallucinogen sticking out of his arm. Many suspects emerge, all with a motive to stop the research project the victim worked on. But can Becker and Woodhead find the truth as events continue to unnerve them--and the killer has them in their sights?
