Lydia Adamson: Dr. Nightingale Rides to the Hounds (USA 1997)

From the Publisher:
When a local bigwig and organizer of the county's biggest fox hunt is shot dead, Dr. Nightingale, veterinarian-turned-sleuth, investigates -- and the fur really starts to fly! With the investigation unearthing bizarre allegations of witchcraft and a possible link to a past killing, this case shows that when you lie down with dogs, sometimes you wake up dead.
