By Aphrodite Jones. The Michael Peterson/Staircase case, in book form. I haven't read this one and I can't say the "STAIRWAY TO HELL" subhed on the back cover is tempting me to try it, but a contemporary genre take on the case is of nominal interest.
This particular copy is in bargain shape -- creased spine, cornerwear, and a couple of stickers as shown -- but the pages are clean and it sits straight.
