Query: Drat, not her best

I've always loved Martha Grimes's work, and was eagerly looking forward to this one. Alas, this is clever, but not her best. Especially, as another reviewer mentioned, the business with the dog. Please, I'd thought we'd gotten past that sort of thing.No need to mention the plot, no need for spoilers. Unsatisfying, indeed. Finally, and this may be from watching too many CSIs, but once you've read it, think about the ending -- and the dog's presence -- and testing for evidence. Couldn't that have been done? I can't say more because it will give the plot away. Hopefully some of you will understand what I'm trying to say LOL.Suspending of disbelief is something readers usually have to do, but Ms. Grimes definitely has tried this fan's patience with this one.
