Query: Cover of book uses notoriety of San Francisco Zodiac as major selling point.

I have not read this book but when I came across it at the book store one day I immediately recognized that the author uses the notoriety of the San Francisco Zodiac murders as his selling point. I am very familiar with the San Francisco Zodiac killings and I admit for a second that I thought the murders had been solved until I realized that the picture of the man on the cover looked too young to be the Zodiac from the late 60's. The release of ZODIAC in 2007 may inspire some viewers who are unfamiliar with the case to want to read the books by Robert Graysmith and may also buy this book as well thinking the case has been solved.
