Covert-One (Patrick Larkin) Books in Order

Patrick Larkin's two Covert-One novels sit inside a larger spy-thriller world built around secrets that are too dangerous for ordinary agencies to handle. The stories follow Lt. Col. Jon Smith, an Army doctor with expertise in infectious disease who also works as an operative for Covert-One, a hidden U.S. unit called in when a crisis has international stakes.

Smith is not a conventional action hero who simply chases clues with a gun in hand. His medical knowledge matters. In these books, outbreaks, research facilities, samples, and unexplained deaths can be as threatening as armed opponents. That gives the series a tense mix of espionage, science, political maneuvering, and direct action.

In The Lazarus Vendetta, Smith investigates a devastating attack on a nanotechnology research facility. The apparent culprits are linked to the Lazarus Movement, a radical anti-technology group that has grown out of a broader protest movement. Smith's search brings him into contact with a conspiracy that reaches well beyond public demonstrations and puts huge numbers of lives at risk.

The Moscow Vector starts with a warning from a Russian medical colleague about suspicious deaths in Moscow. When that contact is killed, Smith is left with scattered clues, a missing trail of evidence, and a fast-moving virus that begins striking officials around the world. The investigation leads toward a larger scheme tied to Russian power politics and the possible use of disease as a weapon.

The stakes are global, but the stories stay close to Smith's urgent problem-solving. He works with recurring allies, including intelligence contacts and technical specialists, while trying to separate useful information from traps and disinformation. The pace comes from the clock: an attack has happened, another may be coming, and waiting for perfect proof is rarely an option.

Larkin's entries can be read as self-contained missions, though reading The Lazarus Vendetta before The Moscow Vector gives a useful feel for the series' blend of medical suspense and covert operations. Expect globe-spanning investigations, hidden agendas, and threats that become clearer only after Smith is already in danger.
