The Mozart Code by Rachel McMillan

No matter how you might try to hide in a war to escape your past, it is always close at hand.

Lady Sophia Huntington Villiers is no stranger to intrigue, as her work with Alan Turing’s Bombe Machines at Bletchley Park during the war attests. Now, as part of Simon Barre’s covert team in post-war Vienna, she uses her inimitable charm and code name Starling to infiltrate the world of relics: uncovering vital information that could tilt the stakes of the mounting Cold War. When several influential men charge her with finding the death mask of Mozart, Sophie wonders if there is more than the composer’s legacy at stake and finds herself drawn to potential answers in Prague.

Simon Barrington, the illegitimate heir of one of Sussex’s oldest estates, used the previous war to hide his insecurities about his past. Now, he uses his high breeding to gain access to all four allied quarters of the ruined city in an attempt to slow the fall of the Iron Curtain. He has been in love with Sophie Villiers since the moment he met her, and a marriage of convenience to save Simon’s estate has always kept her close. Until now, when Sophie’s mysterious client in Prague forces him to wonder if her allegiance to him—and their cause—is in question. Torn between his loyalty to his cause and his heart, Simon seeks answers about Sophie only to learn that everything he thought he knew about his involvement in both wars is based on a lie.
