Murder gallops after Jessie when an emergency call sends the traveling vet to a posh Long Island estate with her one-eyed Dalmatian, Lou, and her tailless Westie, Max. A prized Arabian steed needs minor medical care. but it's the rider who grabs Jess's attention. The handsome young horseman exudes plenty of animal magnetism as he canters across the field...and then takes an inexplicable, fatal fall.

The dead man was one of the finest polo players in the world, but it was no accident that killed him. The culprit was poison. And as Jess soon discovers, a number of people had the means, motive, and opportunity for foul play.
