The book is interesting, if not particularly well-written; contains lots of information about the "trailside killer" in the SF Bay Area. Contains lots of information about the background of the killer, and about the killings.
I'm not sure I'd recommend buying it, being out of print, but it's certainly worth checking out of the library.SFBA's other serial killer. No surpise that Graysmith's sophomore true crime book (his first being Zodiac) would be about the Trailside Killer. I remember his rampage well, having spent my entire life in the San Francisco Bay Area. Although not quite as well written, it still is a fascinating look at San Francisco's "other" serial killer.
