By Joe McGinniss. Cruel Doubt is "the D&D one" and I've reread it several times; something about the attorney's investigator calling Chris Pritchard a "silly little son-of-a-bitch" is so satisfying. The bogeyman of Dungeons & Dragons, less so, but...that was the eighties for you.
Some shelfwear to this paperback, edgewear, a cracked spine. A great commuting copy.
