The More the Terrier by David Rosenfelt
This series has the cutest covers.
This is the typical Andy Carpenter book. We've got a rescue dog, an innocent client, and a possible mob connection. That being said, the formula works every time, mostly because Andy is a great character. He's funny, smart, self-effacing, sarcastic, and loves dogs. And the narrator, Grover Gardner, pulls it off wonderfully. Andy's friends and family are also likeable and well-developed, if a bit quirky at times.
The mystery itself is well-done, with plenty of red herrings and potential suspects. I like how all of Andy's team gets in on the action.
While the story takes place around Christmas, the holiday does not impact the story much. It's not a book I would feel the need to save till December....
