OK so it turned out that Camille was in on the secret and they didn't actually kill Lisa. But I thought it was actually Camille who fell down the flight of stairs, possibly dying. It was the girl who was the dancer? Who was the girl who was dressed as Little Red Riding Hood at the masquerade dance? I am so confused!

Camille never wanted to harm or "get rid" of Lisa like how the others agreed upon. So, from the moment she goes to "talk" to Lisa, her entire intent was 1.) keep Lisa alive, ultimately to use her to, 2.) deceive Will into depositing 4 million into that account, & 3.) use her actor friend to frame him or get him into legal trouble by some means, so, as his fiancée, she gets huge publicity by association
Thus now making her a prime candidate for that Broadway lead role that so badly needs a "face" people can recognize
Bam. That's it. She's as egotistical as the dude, but, not a killer, so she's the good guy here. But it's all *beep* up really
