Tacked to Death — A.K. Alexander

A new tack shop and a gala polo match are reasons to celebrate for horse trainer Michaela Bancroft -- until equestrian Sterling Tabor is found clubbed to death with a polo mallet. Worse yet, suspicion falls on Michaela.... The weapon belongs to Michaela, her prints are all over it, and rumors of her alleged affair with the victim aren't helping. With her boyfriend, Detective Jude Davis, out of town, Michaela doesn't stand a chance of proving her innocence and clearing her name unless she delves into Tabor's mysterious life -- and death -- on her own. But in unearthing a real suspect and a motive, she discovers a deadly past. And Tabor's shady friends are more than willing to throw Michaela off the track -- for good.
