Query: Weak Point in Barr's Series

I've enjoyed most of the Barr series as light mystery fare with a interesting, spunky protagonist. The character of Anna Pigeon has always spoken to me in these books. However, I borrowed this audiobook to entertain me on long driving trips and was disappointed. The story is not a taut as her others. Usually the storyline contains a window into the Pigeon's personality and psyche, which long-time readers expect, but this book just plods along without any personal focus on Pigeon and proceeds to the end of a pretty rote, predictable mystery plot.
