EDIT: Nevermind. The Necronomicon goes in your threat are, not your play area.
In addition to the other good reasons to run her in Daisy Walker, I believe she enables you to get rid of your weakness "for free." You can't choose to discard a weakness from play, but you can choose to attack your Necronomicon to Abigail. And if Abigail were to leave play, then all her attachments would be discarded. So, try running her with Calling In Favors and Art Student, or another cheap Seeker ally. If you don't draw Abigail, you can use Calling In Favors the normal way: Play an art student, return them to your hand, and try to find Abigail. But, if you do draw Abigail, you can hang on to your Favors until you draw the Necronomicon. Attach it to her, bounce her to your hand, try to hit an Art Student for a free clue, then reply her at leisure.
