When she threatens Justine, Thomas breaks a metal chair over her head, then pins her to a table and lets Justine kiss Madeline's forehead, burning the flesh while Madeline screams. Thomas tells Harry their House has firm rules on poaching, Madeline deserved it, and she had to be shown.
It comes out that Madeline had tampered with the mind of Evelyn Derek and paid her to hire a detective, and sent the hitman Binder and his Grey Suits after Harry. And she most likely sent "Shagnasty", the Naagloshii to the Raith estate suspecting that Harry and Anastasia Luccio were telling Lara Raith information that would finger her. Harry brought it to Lara's attention. 
On Demonreach, Madeline and Binder attack the Council with Grey Men. She subdues Harry with her White vampire mojo, then nearly shoots him in the head. William Borden and Georgia stop her and take her on. They scatter when Harry warns them of Binder and his gun. She goes for Harry who shoots her several times, but she keeps coming. She is stopped and killed by Lara Raith. Madeline affected Will Borden and Georgia in a way that took them out of the battle, but didn't harm them in the long run.
