Query: curiosity killed the Kat!

Robert Graysmith's first book ZODIAC I must admit to having read 5 times since it first came out. In the back of my copy are many articles clipped over the years on Z. I grew up in Marin county California and was a teen during Z's reign if terror. Robert Graysmiths 2nd attempt failed to ignite my fire. Frankly, his "facts" concerning ALA left me shaking my head. Hmmm... I see its listed used at Amazon for $2. Its worth it for that price. But don't spend $25 as I did on the hard cover. Will the identity of Z ever be known? Would he be so popular if he'd been caught? I don't think so. We, those interested in Z, have that intense desire to know who he is. I honestly can understand RG's obsession.
