Anna Castle writes three series: the Francis Bacon mysteries, the Professor & Mrs. Moriarty mysteries, and the Lost Hat, Texas mysteries. She has earned a series of degrees -- BA in the Classics, MS in Computer Science, and a PhD in Linguistics -- and has had a corresponding series of careers -- waitressing, software engineering, grammar-writing, assistant professor, and archivist. Writing fiction combines her lifelong love of stories and learning. She physically resides in Austin, Texas and mentally counts herself a queen of infinite space.
