Veterinarian Deirdre "Didi" Nightingale is happily taking a break from her practice to join a research team tagging pregnant black bears in the northern Catskills. Awaiting her are the thrill of adventure, the fun of taking her friend Rose along--and murder.
No sooner do se and Rose arrive at the base camp than they run into the bullet-riddled body of the caretaker. Although local police insist the murder has nothing to do with the scientific expedition, Deirdre feels something fishy is afoot in bear country. She soon finds the paw print of a monster-size bruin, a creature that is a Catskills legend--and a growing reason to suspect one of her group is a killer. Meanwhile, the woods are lovely, dark, and deep. And, for a vet on the trail of a murderer, most deadly.
