A whole lot of fun, an equal amount of creepy, and a pinch of wtf is going on here.
I'd never enjoyed reading a play, after having already seen it, as much as I enjoyed this one, and that's saying something because I don't usually read plays unless they're assigned reading.
Highly recommended for people who like metafiction and mind games, as this is a story within a story pretending to be an imitation of a play for the purpose of carrying out the perfect murder. You'll never guess who dies, who really dies, who's behind it all, or why. Well, unless you've seen the play or read a couple of the reviews on the book page. Seriously, people, there's a spoiler html script for a reason.
So, yeah, give this one a try. Hard copies might be hard to find, but I'm sure your local library has a few that haven't been checked out in years.
