College professor Sam Teagarden stumbles upon a decades-old government cover-up when an encoded document mysteriously lands in his inbox, followed by a cluster of mini-drones programmed to kill him. That begins a terrifying flight from upstate New York, to Washington, to Key West, as Teagarden must outfox teams of hitmen equipped with highly sophisticated technology. While a fugitive, he races to decode the journal, only to realize the dreadful truth --- it’s the reason he’s being hunted because it details criminal secrets committed by the U.S. in the 20th century. If he survives and publishes the decoded diary, he’ll be a heroic whistleblower. But there is no guarantee. He may also end up dead.
