Trixie Belden first appeared more than 50 years ago in The Secret of the Mansion, which was followed by 38 more adventures as generations of readers grew up with teenage detective Trixie and her mystery-solving friends.

Now, Trixie is back with a fresh look and ready to charm a new band of sleuths!Trixie Belden is bracing for one boring summer. Her lucky older brothers are away at camp, so she is stuck babysitting. But when a new girl, Honey, moves in down the road, Trixie finally has the chance to make a best friend--and Honey isn't the only fresh face in town. The girls spy someone inside a nearby house, which is curious because Trixie knows her grumpy old neighbor, Mr. Frayne, is sick at the hospital.

There's only one reason why someone would go poking around Mr. Frayne's run-down manor. They must be looking for the fortune that is said to be hidden on the property. But that's only a rumor...right?

Trixie wished for an adventure, and she might just get her most exciting summer yet!
