By Robert Graysmith. “The Identity of America's Most Elusive Serial Killer Revealed”; this edition includes “new material on the making of the film.” The ROI is not great with this second Zodiac book, I'm sorry to say, but there are a lot of photos, they are exclusive, and if you're obsessed with this case, this is a must-read.
This paperback is in decent shape: mild shelfwear, a cracked spine, and a bit of toning to the pages, but sits straight, clean and readable within.
