The first Battle story, but more importantly, the introduction of Bundle! Very much in the flavor of Nancy Drew, full of intrigue and secrets, all wrapped up in an English country home. 1964 Dell first paperback edition. Good vintage condition, with sun fading on spine and slight lean. See photos. Page edges stained red. Interior clean and unmarked, binding tight. 45 cents on cover! One of my favorites! This is a duplicate in my collection.
