It took me a good bit to get into this book, but I did grow to enjoy it. There were times that I found it quite tedious, but on the whole I liked the story. I do think that you must like the original play as a prerequisite to this book, though; it stands strongly as a prequel but not very well on its own.
I hated this. It made me genuinely angry, to a point where I'm finding it difficult to write this review. Nothing happens, the mysterious murder is nothing, the writing is atrocious, and the biggest victim of the book is never acknowledged.
