The Fox Hunt Mystery — Carolyn Keene

Nancy's friend Laura Passano has invited her down to Maryland to enjoy a horseback riding holiday. The weather is wonderful, the pastures peaceful, the trip a real treat. There's only one catch: Someone's out to sabotage the Passano family stables. First, the feed is poisoned, and then Laura's favorite horse, Morning Glory, is stolen!

Did Alexa Shaw, Laura's spoiled rival, find the perfect way to hurt her? Or has the upcoming fox hunt so enraged animal activists that they've turned to sabotage? Spurred to action, Nancy's on the hunt for a lawbreaker -- and she's headed straight into a hornet's nest of greed, jealousy, deception, and dangerous secrets!
