This book is an extremely well written and highly educated study of two elusive killers, one of whom (the Unabomber) was captured only when his writings were recognized by a family member nearly 18 years after his initial rampage began; the other (Zodiac), who has evaded identification for close to 40 years but who, by all accounts, shares nearly identical parallels in tactics, motive, writings, codes, threats and knowledge and movement of the San Francisco area.

Theodore Kaczynski, aka Unabomber, terrorized the public beginning in 1978 until his capture in 1996 when his brother went to the police after he felt he recognized some of the writing style within the Manifesto of the then-unidentified Unabomber, who used the threat of further bombings if his writing was not published.

Astonishingly, upon his capture, it was found that the Unabomber suspect, Ted Kaczynski, was an assistant mathematics professor at the University of California, Berkley campus, during key Zodiac events.

This book is a remarkable analysis of the shared similarities of the two killers; most particularly in their uniqueness for communicating through writing to the media, the police and their victims; their knowledge and use of code; their need for public attention and threatening the public.

Letting the reader decide for him/herself, based on the evidence presented, whether or not the Unabomber and the Zodiac could be one-in-the-same, not only is this book an outstanding examination of these two elusive killers for those interested in the unsolved murders of the Zodiac, it presents itself as an exceptional tool for use in any classroom study of criminology or psychology.

Highly recommended
