Greer to Mary in To The Death

Madam Greer Castleroy (born Norwood) is one of the main characters. She was Mary Stuart's lady-in-waiting along with Kenna, Lola, and Aylee. She is now Mary's best friend and confidante. Unlike the others though, Greer is not titled, yet her family is said to be ridiculously rich due to her families former success in the mining business. She is the eldest of five children, all of which are girls, the mother of Martin de Lambert's daughter, the wife of Lord Castleroy and the step-mother of Yvette CastleroyGemma Castleroy, and three other unnamed step-children. She had been sent to court to marry a man with a title to secure her future and have her family marry into a titled family.

During the series, Greer had a secret relationship with kitchen servant, Leith. She eventually fell in love with him but knew that she cannot be with him due to his status. After the arrival of her fiance, Lord Julien, Greer and Leith were caught kissing, causing Greer's engagement to Lord Julien to be called off and her reputation was ruined. She soon became engaged to Castleroy and Leith is sent into the army. As time went by, Greer got to know Castleroy as he defended her from her father's cruelty, seeing how much Castleroy truly cares about her causing them to grow closer. She was later reunited with Leith and learned he has gained nobility but is not titled. She rejected his offer and stayed with Castleroy.

Some time after getting married to Castleroy, she and her husband were accidentally involved in the payment of the Protestant attack on the castle. They were eventually ripped of their home, money, and his titles. Greer was forced to move away from the castle while Castleroy was sent to prison. Later on, Greer was able to find her own independence by becoming a Madam and opening a brothel. Her and Leith got back together but their reunion was short-lived. He proposed to her but once again, she rejected him. She couldn't rely on him on her future and was finally happy with finding her own independence.

Later on, Greer met a pirate named Martin and began a courtship at Mary's request. However, shortly after, he left the French Court. In The Hound and the Hare, it was revealed that Greer is pregnant with Martin´s child. As Greer planned for her child to be adopted by her sister and brother-in-law, she found out that she was being betrayed by the both of them. They were planning to leave France and get away as far as possible from Greer, without interference from her in raising the child. Greer eventually cut her younger sister and brother-in-law out of her life for good. While she was also trying to keep her pregnancy a secret from Mary by avoiding her, Mary eventually found out. Mary ordered her group of mercenaries to break Lord Castleroy out of prison so that he could be reunited with Greer and be the father of her child. They were given new identities and Greer said her goodbyes to Mary, leaving the French Court.

She later gave birth to a baby girl and returned to Scotland to continue to support Mary.

Greer is also rather stubborn but has a good heart and her reputation matters a lot for her and her daughter

"Greer, because she's not titled, but she's ridiculously wealthy, she's constantly trying to prove herself with her jewels and her fashion...She's always kind of slightly over the top, always kind of acceptable but a little bit over the top. She'll always have big jewels on, we kept her in a lot of emerald, kind of jewel tones, a lot of greens and deep golds and yellows on her. Constantly one too many accessories on her because she's trying a little too hard." Meredith Markworth-Pollack about Greer.
