Sigrid's letter was very detailed and it mentioned Emmah, specifically highlighting that while Lady Jane's daughter had died, Mirena was also giving birth and her child had lived.
Lady Jane Fairfax was a superstitious drunk so Sigrid also added a claim that Emmah had swallowed the luck and life of Lady Jane's child. To take it a step further, she called Emmah a cursed woman.
Using all the people that had been ruined or harmed because Emmah came into their lives, she made clear examples. Her last words were a warning to lady Jane, telling her that the Fairfax family be ruined if Emmah ever became one of them.
She put the letter aside and called for Alistair.
"Make sure that she gets it. It should not fall in the hands of anybody but Lady Jane." she specified.
Alistair nodded and he vanished out of the window with the letter.
