Xanthe Schneider Enigma Thriller

The Xanthe Schneider Enigma thrillers follow an American woman drawn into British naval intelligence during the first years of the Second World War. The Berlin Affair sends Xanthe into Nazi Germany in 1940; The Athens Assignment places her in occupied Greece during the hunt for Bismarck; and The Swiss Appointment moves the intelligence struggle into neutral Switzerland while codebreaking work continues at Bletchley Park.

The trilogy uses fictional missions to connect espionage, naval warfare and cryptography. Xanthe’s personal life and responsibilities as a mother develop across the three books, while the historical framework shifts from the German capital to occupied and neutral Europe as the importance of Enigma intelligence grows.
