His niece, Mary Dillard, believes the killer was another scientist who was trying to ruin his reputation. She hires a private detective, Gunnar Schofield, to investigate the murder. While travelling across the country, the pair learns that a secret society of scientists has been falsifying the fossil record to discredit creationism and support Darwin's theory of evolution. Will she succeed in clearing Wayne Oakford's name? Will the truth about evolution be exposed to the world?
