New York: A. L. Burt, (1930). First edition - The extremely hard-to-find fifth and final book in this series - Linda and Dot fly to Hollywood in the Ladybug to unmask an imposter claiming to be the "famous aviatrix" who would be doing stunts in a new film. Interesting the list of books at the front shows only 4 titles - the first 3 in the series and this one. Jennifer White on her website notes "that every single 'rare' series book on eBay is easier to find than the final two Linda Carlton books. The final two volumes are just about impossible to find and seldom come up for sale. Many years can pass with neither volume 4 nor 5 surfacing." Glossy frontispiece. Illustrated green and white endpapers. 256 pp.
