David Rosenfelt is back with another Christmas-themed mystery in his Andy Carpenter mystery series - The More The Terrier (#1,344). Laurie Carpenter loves Christmas. Andy not so much. But when a small terrier shows up on their doorstep, they're in the mood to be charitable (it's a dog, isn't it?). They think there's something familiar about the dog. It's not a stray because it's obviously well-taken care of, but it isn't until their son Ricky comes home that the mystery is solved. He identifies Murphy by a trick he taught the dog whom they fostered until he was adopted into a loving home. When they return the dog to his owners, a short distance away, the mother is glad to see the dog but distressed because her son BJ is in jail on a murder charge.
Of course, Andy and Laurie investigate. BJ is accused of murdering his professor, a brilliant computer scientist, over a grade dispute. In fact, he has a defense attorney who urges him to plead guilty for a lesser sentence. Andy wants to know how this sleazebag attorney came to represent BJ, and the deeper he digs, the more suspicious the circumstances become. BJ is a pawn in a game some very clever people are playing...
Clever twists and lots of riffs on how much Andy hates Christmas. Entertaining read.
