In this standalone sequel to The Girl From Krakow, the greatest
undisclosed secret of the Second World War haunts the lives of four
people across three continents and fifteen years. The only Second World
War secret not revealed soon thereafter was that the Allies had broken
the German Enigma codes. This secret was kept for 30 years after the
war. In the Shadows of Enigma is a 15 year-long narrative of how knowing
the secret changed the lives of four people: Rita Feuerstahl, who
learned that the German Enigma had been deciphered by the Poles just
before she escaped a Polish ghetto, Gil Romero, her prewar lover whom
Rita marries after the war, Stefan Sajac, the infant son Rita had
smuggled out of the ghetto and lost track of, and Otto Schulke, the
German Gestapo detective who apprehended Rita during the war and
suspected that she knew the secret of the Enigma's decoding.
