High Quality Content by WIKIPEDIA articles! Trixie Belden is the title character in a series of `girl detective` mysteries written between 1948 and 1986. The first six books were written by Julie Campbell Tatham, who also wrote the Ginny Gordon series, then continued by various in-house writers from Western Publishing under the pseudonym Kathryn Kenny. Today the rights to the series are owned by Random House. The series was completely out of print for a number of years, but Random House began releasing a new edition of the books in summer of 2003. As of summer, 2006, volumes 1-15 have been reissued. Fans of the series hope to see all thirty-nine volumes reprinted, especially the hard-to-find volumes 35-39.
