Sorry, but from your statement that Olga “caused dissension” and your reference to “her feud” with emotionally unstable, jealous and insecure Marie, I assumed you must not have read those books. Olga’s main offense was that she possessed everything that lazy self-absorbed Queen Marie lacked: classic beauty and style, a husband who not only respected her, but was a real friend, and an important rôle to play after King Alexander’s assassination. The feud was an unhappy self-pitying Marie thing, not something the Regent couple went looking for- they had more than enough to deal with in those turbulent years.
