Funny how we don't hear much from Melanie Travis's brother Frank in her previous mystery adventures. We know he exists, and we've seen him a few times during family get-togethers; all the same, I'm sure Melanie prefers not to have him around, for when he is he's either raiding her refrigerator or asking for money.In Watchdog, Frank is asking for much more: he wants his sister to help clear his name when a business associate is murdered.Frank's latest big venture in a string of failed jobs and prospects is a coffee bar in a nearby Connecticut township. Locals are protesting the business, and one would that was the worst of Frank's worries. Then his financial backer turns up dead on the construction site, and Melanie -- whose hands are full with dog shows, a new job, and a marriage proposal (finally!) from Sam -- must come to the rescue.Berenson is always a delight to read, with fun characters and lessons in dog grooming. Watchdog is no exception; watch out for this one and for Melanie's future exploits.
