A good overview of the Zodiac case noting the important details such as the cyphers, the mysterious phone calls from the man claiming to be the Zodiac, and the various letters he sent to newspapers across California.
I would recommend this book for people who aren’t familiar with the case or who would like a refresher.
Narration worked well for the material.
This book was given to me for free at my request, and I provided this voluntary review.
