The Enigma Affair

From the publisher: "When small-town librarian Patton Harcourt comes under fire one morning while making profiteroles, she has no choice but to trust the mysterious assassin, Nemo, who shows up in her kitchen. Fleeing a pair of German thugs, the two form an unlikely alliance as they try to decipher a seventy-five-year-old message encoded by Nazis on an Enigma machine. Traveling to Bletchley Park in England, they enlist the aid of Patton’s old flame, Ruthie Drinkwater, an expert on Enigma. The trio soon finds themselves on the run, pursued by both the police and Ingrid Weiss, a white supremacist trying to unlock the secret of Heinrich Himmler’s research into alchemy. In this fast-paced thriller with a thoroughly researched World War II background, a mismatched cadre of heroes, including an art historian, a museum docent, and a collector of Nazi artifacts, must work together to stop a ruthless and resourceful opponent."
