The Zodiac has never been caught. The question remains, where did he go and why did he stop killing? Hunted: The Zodiac Murders follows the murders, letters, codes, and people involved in the mystery of the Zodiac killer, and is widely acclaimed as the most unbiased, most complete examination of the events surrounding this bizarre case. Book 2 in the series, Profiled: The Zodiac Examined goes into the psychology of the killer, and book 3, Exposed: The Zodiac Revealed narrows down the list of suspects.

With the 50th anniversary of the Lake Herman Road attack (December 20, 1968) fast approaching, Hewitt is an excellent resource for interviews and commentary on the case.
