AND YOU'RE TELLING ME JUST NOW?!
Madam Ginger is Duchess Hermine's caretaker who was hired as soon as the Duchess fell ill. She had previously been friends with the Duchess after they often met at the tea parties and became close.
Besides that, she is also a noble but despite having a family with a title, they are not that rich. She married a Viscount, but her husband died of old age after 5 years of marriage with no children between them. She also never married again. Other than this, her record is immaculate. She is too clean that is suspicious which make Ariana do the background check on her.
But, thinking that she was not married yet despite often came to tea parties and balls made Ariana feel weird by it. Madam Ginger also stopped her social activities when the Duke appointed her as Duchess Adeline's personal caretaker. Unlike the other maids or doctors who keep changing because the Duke can't trust them or they make mistakes, Madam Ginger stays on his good side until now.
