Here comes Santa paws / Laurien Berenson.

Enhanced descriptions from Syndetics:

It's the most wonderful time of the year in Connecticut, but Melanie Travis finds surviving this December may take a real Christmas miracle when a yuletide murderer comes to town . . .

As Melanie attempts to deck the halls in a house overrun by pampered Poodles, her event planner friend, Claire, is busy playing Santa-beard and belly not included-for the wealthiest clientele on Connecticut's Gold Coast. A personal shopper gig in the affluent town of New Canaan seems like business as usual. Except Claire's stylish stint comes at a higher price than she bargains for when she stumbles over her newest customer's dead body on the job. Named a prime suspect for murder, she begs for Melanie's help, then vanishes like cookies and milk on Christmas Eve . . .

Determined to track down Claire, Melanie and her nosy Aunt Peg dash into a dizzying investigation that leads to even more questions. Why was homicide victim Lila Moran, a secretive woman with an untraceable past, permitted to live on a well-known socialite-turned-recluse's private estate, and is Claire keeping her own incriminating secrets under wraps? Now, with a grinchy New Canaan detective on their case and disturbing clues piling up like presents beneath the tree, the crime-solving duo must rein in a sinister Kris Kringle before they're the next ones on someone's deadly wish list . . .
