Woman On the Wire (The Ellen Parker Series, Book 3)

In the third of the Ellen Parker novels, it is 2013. From the Carolinas to southern Pennsylvania, someone is killing women and leaving many hanging on barbed wire fences. While the unknown killer is pursued by a multi-agency task force led by the FBI, Ellen Parker, a Philadelphia journalist, is contacted by Iraq veteran Elizabeth Chernov, who has encountered a young girl fleeing from the drug-related killings of her guardians. Chernov believes the girl is pursued by the murderers perhaps aided by the police; she trusts Ellen only because she did a story on her and others dealing with the aftermath of the war. Ellen's attempt to bring the girl and Chernov to an FBI agent is intercepted by the drug gang killers and the two disappear.
The leader of the drug gang has another card to play; he hires a killer calling himself "Dr. John" and working for the Aryan Nation. John is more than he appears, a man so dangerous even the drug gang fears him, and even they do not realize he is the one sought by the FBI. John hunts Chernov and the girl, using Ellen as his guide. Not realizing John is following her, but seeing the killing continuing, Ellen goes to bring in Chernov and the girl. Dr. John comes after Ellen, who finds herself in a life and death struggle to avoid being another woman on the wire.
