Book One of Murders of Substance
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.
The priest, the professor, the piscary president, the protestor, the protégé—they all emerge as suspects to stop the victim's research project, and soon Becker's life is in danger.
Do Becker and Woodhead have a prayer of discovering the truth before more people are killed?
