As Daddy-Long-Legs traced Judy Abbott's growth from a young girl into an adult, Dear Enemy shows how Sallie McBride grows from a frivolous socialite to a mature woman and an able executive. It also follows the development of Sallie's relationships with Gordon Hallock, a wealthy politician, and Dr. Robin MacRae, the orphanage's physician. Both relationships are affected by Sallie's initial reluctance to commit herself to her job, and by her gradual realization of how happy the work makes her and how incomplete she'd feel without it. The daily calamities and triumphs of an orphanage superintendent are wittily described, often accompanied by the author's own stick-figure illustrations.
