I felt a little cheated not finding out more about Margarete— who she was. How she got her training. Lucius wouldn't have been that hard to trace, and she could have found him if she had tried harder. He was from a well-known family; he was working again in Vienna. I also thought it was too convenient that she hooked up with Horvath again, entwining the three of their lives again. Then, instead of thinking how if he hadn't messed up Horvath's life, maybe he could have married Margarete when he found her, he somehow thinks Margarete's marriage is an atonement for his mistake; Horvath is happy, Margarete has a daughter, and Lucius is ready to live in the world again.
