Connie Blair


 * Connie Blair is the central character in a series of 12 mystery novels for adolescent girls written by Betty Cavanna under the pseudonym Betsy Allen. Cavanna wrote volumes 1 through 11. The author of volume 12 remains unknown. The series was published by Grosset & Dunlap between 1948 and 1958. Book titles were distinguished with a color in the title such as The Clue in Blue and The Riddle in Red.
 * The series was initially published with dust jackets. When the first four titles were republished in the early 1960s, however, costs were cut by dispensing with the dust jackets in favor of full color cover illustrations. All twelve titles were published as paperbacks in the 1960s. In 1978, three titles were republished in paperback editions with entirely new cover illustrations.
 * In the beginning, teenager Connie Blair models clothes at an exclusive department store in Philadelphia. She then becomes a secretary at an advertising firm, and works her way to a more important position. Her various jobs are the backdrops for the mysteries she encounters and solves.
