Lydia Adamson: Dr. Nightingale Goes the Distance (USA 1995)

From the Publisher:
Didi Nightingale, D.M.V., is sipping champagne at a pre-race gala at a posh thoroughbred farm, when shots ring out and two bodies are found in the stall of the year's most promising filly. Now Didi is snooping in a world of bloodlines and bloody schemes. The odds are against this spunky vet who may find her heart's desire at stake and murder at the finish line.
