She fears that her grandfather had been killed by the same cult members. Immediately after meeting with Eve, Alice dies in a freak accident that raises Eve's suspicions.
Meanwhile, Commander Whitney asks Eve to conduct an investigation into Frank's death after an autopsy reveals traces of drugs in his bloodstream but orders her to not share any data with Feeney.

Eve and Roarke visit the Athame, a club run by Selina and Alban, and meets Lobar, another one of the cult's apprentices. The next morning, Lobar is found dead in front of Roarke's home, supposedly killed by someone who hates Devil worship. But before that, Alice's brother Jamie breaks into their home to get more data about the investigation into his sister's death.
At Alice's viewing ceremony, a prominent banker in the city, Wineburg, is killed. The investigation leads Eve and Peabody to Isis and Charles Forte who runs a Wiccan shop where Alice used to work till shortly before her death. Though Eve's initial impression tells her that Isis and Charles are innocent, Nadine tells her that Charles' father was a serial killer who killed a number of people in the name of religion.
Roarke finds that Wineburg had been a member of Selina's cult. Eve brings in Selina for questioning. Selina's lawyer Louis, who is also a part of the cult, get frightened after seeing what happened to Lobar and gets ready to confess everything to the police. But before he can do so, Louis is killed by Marium, a girl who has been newly recruited into the Wiccan club run by Isis and Chas.
Eve arrests Charles for the murders but the real killer is still out there and the next victim is none other that Eve herself.

Best scene in story:
Feeney explodes at Eve for investigating Frank's death and keeping the information away from him. Eve, who considers Feeney as her father, is broken by his accusation that she does not know what it means to be a part of a family. Later, Roarke tells Feeney how Eve was forced by Whitney to not disclose investigation details to anyone. He also tells her about Eve's traumatic childhood at the hands of her own father and how she had started considering Feeney in his place for the past ten years.

Opinion about the main character:
Eve does not like to considered emotional or sentimental and tries to hide her emotions all the time. At the beginning of the case, she is confused between her loyalties to the department and her feelings towards Feeney, but still does what is expected of her even if it tears her apart.
