Having just brushed up my Shakespeare I was more-than-usually susceptible to a mention in another book: Sleeping Murder. Since the original publication date is more than 400 years ago, it is quite easy to find a free copy. Total instant gratification!
The saucy Duchess just popped again, as an epigraph in Silent in the Sanctuary, a book with quite a bit of Shakespeare as well.
Curiosity is satisfied, but I did not love it.
After pondering some more: it's all very one dimensional. At the very beginning we are introduced to all the bad guys. We are told and shown that they are bad guys. Bad guys put out a hit on their sister, her second husband, and their four children. For the money. And then the hitman decides to go after the bad guys for revenge. Lots of murder, sure, but no jokes, no reversals, no mystery, only one character ever changes course and no very satisfying motivation is ever given. Without good special effects, which you don't get in a script, there isn't anything else of interest. You'd have to really love going to the theater, or be a superfan of some actor, to be anything more than horribly disappointed after sitting though it. All that murder and yet, boring. The only interesting thing here is that this script didn't disappear.
