Query: What in the world happened . . .?

I've read them all, and I've obviously enjoyed some more than others. But at the very least all of them have engaged my interest enough to get me through the book. All until now. I tried to slog my way through, but ultimately I gave up around page 150 and commited a heretical act among mystery readers -- I turned to the last few chapters just so I could see "whodunnit". Even that was boring. Maybe Ms. Grimes was thinking more about her next (non-Jury) novel, which has received excellent reviews. Whatever the reason, this stands out like a huge sore thumb amongst the generally well-written Jury novels.
