Spies of Texas Books in Order

In postwar Texas, newcomer Jenny Nicolay pushes her way into aspiring investigator Sawyer Finn's business. Rumors of a Russian spy and an encoded message force the argumentative pair to combine their talents and examine their seemingly friendly town.

Jenny returns to Boston to confront her conman father, whose scandal threatens her hopes of joining the CIA. With Sawyer's help, she investigates his claim of being framed and encounters a criminal organization protected by corrupt police.

New CIA recruits Jenny and Sawyer go undercover at Lake Tahoe to track a German war criminal turned assassin. A winter storm traps them among suspicious guests and rival agents as they try to prevent his next killing.

A dying contact brings Jenny and Sawyer evidence of a traitor inside the CIA. Unsure which colleagues they can trust, the rookie agents launch an unauthorized investigation while a pursuing killer and a mysterious British spy complicate their search.

Jenny and Sawyer travel to England to investigate an MI6 agent's wartime murder and uncover a plot against the royal family. Infiltrating an aristocratic estate forces them to navigate divided loyalties before an assassin can act.
