About this ebook

In this New York Times–bestselling true crime memoir, a man’s search for his biological father leads to a notorious American serial killer.

When Gary L. Stewart decided to search for his biological father at the age of thirty-nine, he never imagined his quest would lead him to a horrifying truth and force him to reconsider everything he thought he knew about himself.

Written with award–winning author and journalist Susan Mustafa, The Most Dangerous Animal of All tells the story of Stewart’s decade long hunt. While combing through government records and news reports and tracking down relatives and friends, Stewart turns up a host of clues—including forensic evidence—that conclusively identifies his father as the Zodiac Killer, one of the most notorious and elusive serial murderers in history. Finally, all the questions that have surrounded the case for almost fifty years are answered in this riveting narrative—a singular work of true crime at its finest, as well as a sensational and powerful memoir.

Ratings and reviews

It's very possible Earl Van Best Jr. could have been the Zodiac Killer. *Note: I was originally disappointed there were hardly any pictures as proof of what Gary was talking about, but I later realized most of the illustrations are at the back of the book.

What a job well done by Gary L. Stewart and Susan Mustafa. I'm glad Gary shared his story but saddened that the SFPD were worthless in helping. I wish Gary would have gotten clean answers. One day it may happen. I truly wish he, his biological mother, and his adopted mother a joyous journey. Gary, hopefully you will get that call you've waited for from the Detective that has never called you back. You truly deserve it. God bless.

True crime story by the son of the Zodiac Killer. His discovery of his own disturbing history and the truths, lies, cover ups, twists, turns, heartaches and divine interventions.
