 Near the end of World War II, a German U-boat deposited two Nazi saboteurs on the coast of Maine. History tells us they were quickly captured. But what if there was a third man? A top-secret agent with a long-term mission known only to a select few in the Nazi high command. Men who anticipated the ways that genetic engineer­ing could someday be used to help launch a Fourth Reich.

The agent collaborates with a geneticist and the Ku Klux Klan to weaponize the emerging science of DNA research, first to develop lethal bacteria and ultimately to engineer modifications of the human genome. Until years later, an accidental discov­ery at the U-boat’s landing site provides a glimpse of his mission, drawing Professor Brad Parker and Maine State Police Lieutenant Karen Richmond into a struggle to stop the creation of a new class of neo-Nazi warriors.

 Falling between Robin Cook’s medical thrillers and Robert Parker’s Spenser potboilers isn’t a bad place to live—and this one hits a sweet spot.

—BlueInk Review

A fun, fast-paced medical mystery that adeptly balances scientific intrigue and human drama.


The Third Man continues Geoffrey M. Cooper’s reputation for producing flawless, thoroughly engrossing medical thrillers. There are many mirrors between this book’s thriller and suspense action and real-world headlines today. Perhaps that’s what makes it especially intriguing and frightening and hard to put down.
