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.” —The Seattle Times “Parents, be warned: Nostalgic feelings may draw you in, causing a tussle over who’s going to read first.”—The Dallas Morning News
