Di Lynch’s Uncle Monty has invited Trixie, Honey, and the rest of the Bob-Whites to his Arizona dude ranch for winter vacation. There will be lots to do—horseback riding, swimming, festivals—but Trixie is hoping for an activity that isn’t on the usual list. She wants another mystery.

When Trixie Belden and Honey Wheeler find a cut diamond embedded in the dirt floor of the old abandoned gatehouse, they set out to find whoever left it there.

Not long after her family becomes wealthy, Diana Lynch's long-lost uncle appears and starts ruining her social life, causing Trixie Belden to investigate whether Uncle Monty is an imposter out to steal the Lynch fortune.
