By Edie and Ray Gibson, and Randall Turner. Gotta "love" the raised-elements school of cover design, like we won't get that it's a locket or something. Also, what's with the WGA precision on the byline? Did it really take three people to write up what sounds, I'm sorry to say, like a fairly straightforward murder story?
In any event, a previous owner loved this paperback well, and it has a cracked spine, page toning, edgewear, and a loose-ish front hinge -- but the pages are tight, and with the exception of the stamps on the edges and flyleaf they're fairly clean as well.
