The Secret of the Mansion / The Red Trailer Mystery / The Gatehouse Mystery (Trixie Belden)

Spunky tomboy Trixie Belden can’t stay out of trouble . . . or stay away from mysteries! And now Trixie’s first three adventures are available in a boxed set of the retro books with Julie Campbell’s text from the 1940s editions and Mary Stevens’s original line drawings. After all, who can resist tomboy Trixie; her rich best friend, Honey; and their adventures with a runaway kid in a miser’s mansion, a stolen red trailer, and a lost diamond in an rickety old gatehouse?
“This younger girl detective is full of spunk and fun. . . . Your readers will be hooked. These stories are set in the ’40s when kids had plenty of time and freedom to explore old mansions and neighborhood mysteries.”
