By Steven Naifeh and Gregory White Smith. The "other" book on the Mark Hofmann/Mormon forgery case, and it is a unit at 500+ pages.
Cracked spine to this paperback, plus mild edgewear, and some waviness/water damage to the first 100-ish pages -- but it's readable enough, and while there's a page missing at the back, there's also some reading notes from a previous owner, so if this is homework, it's half done for you...?
