Born Anna-Maria Devoto de Martinez von Schönberg, she is half-Spanish, half-German. Anna von Menen is a woman of weak health but resolute spirit, and holds the absolute trust of her husband and son.

Klaus von Menen was an Oberleutnant in the First World War and has risen to the highest rank of the German Army. But when we first meet him, the General is being made redundant, shuffled off to the Fuhrer Reserve.
Deep down, General von Menen knows that Germany will lose the war and fears the Russians will soon destroy the family estate at Mecklenburg. His number-one priority is to keep his family and friends safe.
When Carl von Menen boards the Cabo de Hornos for his voyage to Argentina, his mind is full of the dangers he faces in his new and uncertain role as a double agent. But no sooner has he set foot on deck than he meets a welcome distraction, in the form of the beautiful and intelligent Dr Maria Gomez.

Carl von Menen is the protagonist of Out of Mecklenburg: The Unwilling Spy. He is only 28 at the start of the novel, a talented young diplomat who works at the German Foreign Office and keeps his loathing of Hitler well hidden.

Carl von Menen is 28 years old, suave, wealthy and a rising star at the German Foreign office, yet he lives a duplicitous and dangerous life: he abhors the Nazis and wants Hitler dead, but his expectations of seeing a Nazi-free Germany shrink to despair, when he is unexpectedly assigned to Buenos Aires to keep a watchful eye on the emerging United Officers Group (GOU), a pro-Nazi/Fascist faction of military officers, led by the aspiring Colonel Juan Domingo Peron.
In Buenos Aires, von Menen is sucked into a cauldron of treachery, deceit, military revolutions and murder, heightened by the agony of his secret ideology, the long-reaching tentacles of the Gestapo and his clandestine dealings with Colonel Filipe Vidal, a man with a devious and sinister agenda.
