An explosive and historic New York Times bestseller of true crime and an emotionally powerful and revelatory memoir of a man whose ten-year search for his biological father leads to a chilling discovery: His father is one of the most notorious-and still at large-serial killers in America

Soon after his birthmother contacted him for the first time at the age of thirty-nine, adoptee Gary L. Stewart decided to search for his biological father. It was a quest that would lead him to a horrifying truth and force him to reconsider everything he thought he knew about himself and his world.

Written with award-winning author and journalist Susan D. Mustafa, The Most Dangerous Animal of All tells the story of Stewart’s decade-long hunt for his father following a complex trail of startling twists and connections. Combing through government records and news reports and through conversations with his father’s relatives and friends, Stewart turns up a host of clues, including forensic evidence, identifying his father as one of the most infamous and still-wanted serial killers in American history.

Any additional comments?

I think the Zodiac killings are fascinating and was exciting to download the newest in the serial killers' saga. I found myself disenchanted with this book until the final part. If you are a fan of true crime and/or the Zodiac killer, stick it out until the final pages of the book and you won't be disappointed.

Interesting, but not what I expected

I enjoyed this book at first, but is seemed to drag on forever before it ended. I am sure it is because they wanted to get all of the facts about the killer in the story. I gave it 4 stars.

Engrossing! I Couldn't Stop Listening.

A moving, engrossing memoir, read by the author in a simple, heartfelt manner. I highly recommend this book.

narrator takes a little getting used to.

Sounds like he's reading a children's book to an 8 year old. Still a good book though.

Tough Story

This was a really tough story to listen to. It is the story of a local man who, in looking for his birth parents, finds that his birth father is a serial killer. He wrote and narrated the book himself and did an excellent job. Lots of research and documentation went into creating a deep but troubling story.
