I'm not one who tries to "outguess the author" when I read mystery novels or watch movies. I enjoy the ride. So maybe I'm not the target audience for this piece.
CUFF contains a really fun play idea--I just had a hard time getting it going. The first playthrough, I threw the wrong guy in jail (sorry!). The second time, after I thought I'd exhausted the number of items I could examine, I hit a wall. Almost none of the descriptions repeat themselves more than once, so I reached for the walkthrough.
I don't think I would have solved the crime without it. Even after the walkthrough, I didn't quite catch the thread of logic. But I also feel this way after reading some mystery novels, so it could just be the way my head works.
Definitely play this one--the writing is a plum, perfectly in-genre--just know it takes a very careful eye to untangle the real mystery.
