Death by Dressage — Carolyn Banks

NIKA BALLINGER IS A BLUE RIBBON BITCH

She's sly, selfish, and second-rate, a spoiler of horses and men. And she's come a cropper at last, with only a rich husband to mourn her violent death, which appears to be murder.

Be that as it nay, fellow horsewoman Robin Vaughan doesn't like the way the police investigation is going. In the perfect world of competitive dressage, Nika rode like a piece of luggage. So who arranged to have a horse kick her to death? As Robin mounts her own search for the killer, she rummages through Nika's untidy past-and finds a bizarre double life that someone might kill to keep secret.
