The Saddle Club is taking part in a big Pony Club rally at Pine Hollow. Riders from all the local Pony Clubs are taking part, including Stevie's boyfriend, Phil Marsten. For once Stevie and Phil aren't being too competitive, so everyone is having a good time - until a thief spoils the fun by stealing $500 from the stable office.
Veronica DiAngelo says she saw Phil hanging around the office and acting suspiciously. And Phil did need money. But he'd never resort to theft, would he? Could Veronica possibly be telling the truth? Or is there a thief among the riders? It's up to the Saddle Club to find out and clear Phil's name.
