THE END OF AN EPOCH (1901) – Written by A. Lincoln Green, this novel about a world-threatening disease presented the tale of brilliant young Adam Godwin, a recent Oxford graduate who pursues his interest in microbiology. During the course of his research into antitoxins, Adam becomes aware of the controversial Dr. Azrael Falk.
Falk is in India, experimenting on human test subjects with his hybrids of assorted bacteria and other microorganisms. Godwin becomes so fascinated with Dr. Falk’s heinous yet productive work that it strains his relationship with his fiancee Evelyn Morpeth, daughter of the wealthy Sir John Morpeth.
Ultimately, Adam starts neglecting Evelyn to the point that she lays down an ultimatum: Godwin must choose between her and his research. Adam chooses his research, so the engagement is ended, and the willful Evelyn joins her father’s expedition to the North Pole.
Dr. Falk relocates to London and hires Adam Godwin as his assistant. Adam’s admiration for the man’s scientific genius increases even as his personal dislike for Falk’s selfish nature threatens to overwhelm that admiration. When Azrael sufficiently trusts Adam, he reveals to him that he has developed a combination of dengue, tetanus, influenza, sleeping sickness, bubonic plague and meningitis. Continue reading
