The Most Dangerous Animal of All was co-written by the estranged son of California’s infamous Zodiac killer to reveal his father’s true identity. When the book hit the streets the skeptics were in full force. Just like those who mocked the boy who cried wolf, no one could blame them. Too many people had already claimed to either be the killer or to know who he really was. Forensic science helped solve the killer's identity.

The problem is—the skeptics weren’t considering the handwriting comparisons skillfully performed by Document Examiner, Michael Wakshull, to finally crack the case.

The End of the Zodiac Mystery will enable you to reach your own conclusion whether this decades-long cold case has finally been solved. In it, Wakshull walks you step-by-step through his intriguing forensic science analysis, revealing the methodology he used to solve the case other document examiners refused to accept.

There is a twist to every story, and his methodology required a twist, too, in order to ensure a credible conclusion.

Where The Most Dangerous Animal of All leaves off, The End of the Zodiac Mystery picks up, sharing actual handwriting comparisons between Earl Van Best Jr. and the self-named Zodiac killer. It is virtually certain the documents were written by the same man.

If you like surprise endings, don’t start reading from the back of the book. Save the thrill in the epilogue for the end!
