New York: Grosset & Dunlap, (c 1948.). Hardcover - "The pen name of Betsy Allen conceals one of the most outstanding writers for girls of our day. In Connie Blair, typical teen-age American girl as far as looks go, but with a lively intelligence and a keen nose for solving mysteries, the author has created her most appealing character. Connie is a career girl, with a job in an advertising agency, but mysteries have a way of rising up to challenge her wherever she goes." Considered one of the best written of the girls' mystery series. 216 pp.
