Book 1

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!

Book 2

Trixie Belden's best friend Jim ran away before anyone could tell him that he is the heir to a major fortune. Trixie and her friends set off on a road trip to find Jim--and uncover another mystery along the way!

When Trixie Belden’s friend Jim runs away, she and her neighbor Honey jump in an RV and hit the road. Someone has to tell Jim he inherited a fortune—but he needs to be around to claim it!

Unfortunately, Trixie and Honey’s troubles are only beginning. The girls learn there’s been a string of break-ins to campervans, making travel more dangerous than ever. What’s worse, a young girl named Joeanne has disappeared into the woods, leaving her family and their shiny red trailer behind. Trixie and Honey worry that Joeanne could be in danger—and the fear only grows as the car bandits get more bold. The race is on to Jim and Joeanne and untangle the mystery of the road trip thieves before the burglars hit the brakes on Trixie’s adventure once and for all.

Book 3

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 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.

Book 4

There's a new face in Sleepyside, and Trixie Belden is sure this stranger is up to no good. Too bad no one else believes her. But if anyone get can to the truth of this visitor's true motives, it's detective Trixie!

Trixie Belden hasn’t talked to Diana Lynch in a long time—not since her family got incredibly rich…and snobby. But when Trixie and her best friend, Honey, spot Diana looking a little down, Trixie knows it is time to put old grievances in the past.

Except the past is exactly the problem for Diana. Her long-lost uncle Monty has recently arrived from Arizona, and Diana is less than thrilled about the reunion. Monty insists on hosting lavish parties, he won’t stop pulling pranks, and he embarrasses Diana in front of all of her friends.

Trixie isn’t charmed either. Monty may have fooled all of the adults, but his timing seems too good to be true. But can Trixie prove Uncle Monty is an imposter—or will Di be the one sent packing?
