## Original six written by Julie Campbell Tatham

1. The Secret of the Mansion (1948)
The book opens with thirteen-year-old Trixie begging her mother for a horse. Her two older brothers are away at camp for the summer, and Trixie is afraid she will be bored at their house, Crabapple Farm. The family cannot afford a horse, so Trixie is told she will have to save her money to buy one. She then sees a horse trailer outside a neighboring mansion. The Wheelers, a rich family from New York City, have just bought the mansion and are moving in with their teenaged daughter, Honey. Although tough Trixie thinks Honey is a sissy at first, they soon become fast friends. Trixie realizes that Honey really is a "poor little rich girl", her parents are never home, she has been very sickly, and she grew up at boarding schools, at camps, and with governesses. Trixie helps her new friend overcome these problems, while Honey balances Trixie's rash and impatient personality with her tactfulness and gentleness.
Recently, Trixie's neighbor on the other side was taken to the hospital with pneumonia. Trixie uses this chance to explore around the miser's rundown old mansion. Under the pretense of locking a window, Trixie and Honey climb inside to look around. They are shocked to find a tall, redheaded boy asleep on a mattress. The boy is Jim Frayne, the miser's 15-year-old great-nephew, who is running away from his abusive stepfather. The three become close friends, with the girls smuggling food to the mansion for Jim. Local legend says the old man hid his fortune in the house, electing to live in poverty after his beloved wife’s death. Honey and Jim are doubtful, but Trixie is sure the money is there somewhere if only they can find it before Jim's evil stepfather comes looking for him.
Eventually, Jonesy, the stepfather, does come after a newspaper article about an airplane crashing near the miser's mansion also features the news of the miser's death, the legend of the fortune, and a photo of a fireplace with Jim's silver christening mug on the mantle. Trixie finds the engagement ring that Jim's great-uncle gave his wife in a safe.
After Jonesy shows up, Trixie wakes up in the middle of the night and sees smoke from her window. The girls call the fire department and go to warn Jim. The mansion is burned almost to the ground, and Jim sleeps in the hidden summerhouse. When Trixie and Honey go there to the next morning to visit him, they find him gone and a note with the engagement ring in the summerhouse saying goodbye. He has run away again, this time in possession of some money he found hidden in the mattress he had been sleeping on.
The girls meet the great-uncle's lawyer, Mr. Rainsford, who tells them Jim's uncle set up a half-million dollar trust for him and that Jonesy will be replaced as the boy's guardian. He asks them to track Jim down.
2. The Red Trailer Mystery (1950)
Jim Frayne ran away at the end of The Secret of the Mansion, but later his great-uncle's lawyer showed up, revealing that Jim inherited half a million dollars and is going to be removed from his abusive stepfather's custody. So Trixie and Honey set off in the Wheelers' trailer with Honey's governess Miss Trask to find their missing friend. They decide to check the boys' camps upstate since Jim mentioned getting a job there, but he always seems to be one step ahead of them.
On the trip, Trixie and Honey are faced with: a strange and poor family in a luxurious trailer; that family's missing daughter; Mrs. Smith, a fat and motherly woman who's missing her locket; a trailer-robbing ring; and two suspicious workers at their trailer camp who may be involved.
