Query: Very disappointed long time MG fan

I'm a long time fan of Martha Grimes, Richard Jury, Melrose Plant and the entire crew. This book was a BIG disappointment. I hung on through the anthropomorphism of Mungo (the dog) which really tested reality. I was waiting for that surprising, clever ending that would make everything worthwhile. It didn't come. The story just stopped. Nothing....all of a sudden an epilogue that didn't wrap up anything either.Very disappointed. I'm not sure what that was about. Did she just get tired and decide she'd written too many words?
