An ex-lover of Dwight McCarthy, she manipulates men with her good looks and an innocent facade for her own personal gain or amusement.

An expert liar, she is considered a goddess by Manute, her towering manservant, and a "manipulative bitch" by Dwight.

She had broken his heart nearly four years prior — a month or so before John Hartigan's release from prison in That Yellow Bastard — but he agrees to meet her.

Ava arrives late and tries to persuade Dwight to take her back, claiming that her life is "a living Hell."

Ava appears, and explains how Dwight was all a part of her plan to get Damien murdered so she could inherit his estate.

They interrogate Agamemnon, who defends Dwight as an upright man who went clean after a wild youth of alcoholism.

When they speak with Dwight's landlady, she says she let Ava in the night of Damien's murder, and heard a loud fight.

Ava, with her late husband's financial assets, is joining her corporation with the mob boss Wallenquist.

Ava then tries telling Dwight that Manute had her under mind control to manipulate her and Damien and that it would be a cruel irony if he killed her now.

In the film, Ava is portrayed by actress Eva Green, whose role was announced in January 2013.
