When Pru Marlowe takes a dog for a walk, she doesn't expect to find a body. But Spot, a service dog in training, has a good nose that leads her right to the remains of a beautiful young woman. Despite her best instincts, Pru can't avoid getting involved. The young woman seems to have been mauled by a wild cat, but Pru knows there have been no pumas in the Berkshire woods for years. And while Wallis, Pru's curmudgeonly tabby, seems fixated on the idea of a killer cat, Spot has been sending strange signals to Pru's own heightened senses, suggesting that the violent death was something more than a tragic accident. As motives multiply, a cougar of a different sort sets her eyes on Pru's sometime lover, and another woman disappears. With panther panic growing, Pru may have to put aside her own issues - and her own ideas of domesticity - to solve a savage mystery.
