Trixie Belden and her best friend Honey are exploring an old gatehouse when they unearth a diamond hiding in the dirt. Has a jewel thief come to Sunnyside? No secret can stay buried long when detective Trixie Belden is on the case!

Trixie Belden loves to investigate, and this time, she and her best friend, Honey, have their sights set on the old run-down gatehouse. No one has touched the building in years, making it the perfect headquarters for their new detective agency. But far more than cobwebs and dust wait inside because buried in the dirt, the girls discover...a diamond!

How could anyone have forgotten such a precious jewel? Trixie is convinced a thief walks among them. And when a few workers suddenly join the staff at Honey's manor house, Trixie has her prime suspects.

This amateur still has a lot to learn about sleuthing, though. If Trixie can't stop attracting attention, the jewel thief just might set their sights on her.

In the 1940s, Julie Campbell was running her own literary agency when Western Publishing put out a call for talented authors to write mystery series for kids. Julie proposed the Trixie Belden series and wrote the first six titles herself, but books seven through thirty-nine were written by a variety of writers all under the pseudonym Kathryn Kenny.
