Racine, WI: Whitman, (1966). Hardcover - The thirteenth title in the series, in this slightly larger format (used only on the 1st 15 titles of the series, between 1965 and 1969), with matte illustrated boards and full-color endpapers with oval portraits of Trixie and Honey. The first books in this series introduce most of the major characters and develop a sense of place; Trixie's home in the Hudson River valley was modeled on Campbell's own home (just as her younger brother Bobby was modeled on her son). Although commissioned by the publisher to compete with the Nancy Drew series and other popular series, this is in many ways the opposite of Nancy Drew. Trixie is a real girl, who learns from her mistakes and and is all too quick sometimes to jump to conclusions about people. 15 titles listed in book. Cover by Paul Frame and illustrations by Haris Petie in both full color and duo-tone. 254 pp.
