UNSUB

Twenty years ago the Bay Area lived in fear of the Prophet, a ritualistic serial killer who taunted police, left Mercury symbols at his scenes, and was never caught. The detective who led the hunt, Mack Hendrix, lost his career and nearly his mind to the case.

When the Prophet resurfaces, Mack's daughter Caitlin — now a narcotics detective — transfers to homicide and takes up the pursuit. The killer knows exactly who she is, and the investigation quickly becomes personal in ways that echo everything that broke her father.

Inspired by the Zodiac killings, UNSUB is a tense, procedural thriller about obsession and inheritance, and the opening book of the series that continues with Into the Black Nowhere.
