Julia Clara Catherine Maria Dolores Robins Norton Birk Olsen Hitchens, better known to mystery fans as Dolores Hitchens, was born December 25, 1907 in San Antonio, Texas. She married Beverley S. Olsen, a radio operator on a merchant vessel, around 1934. Beginning in 1938, Dolores wrote a series of mysteries as D. B. Olsen. It is not known whether she divorced Olsen or was widowed, but she was re-married to Hubert A. Hitchens by the early 1940s. After her marriage to Bert—who was a railway detective—they collaborated on a series of five railroad mysteries from 1957 to 1964. Dolores also wrote an excellent group of standalone mysteries, including Fool's Gold which was filmed by Jean-Luc Godard as Band of Outsiders in 1964, as well as the critically applauded Sleep With Strangers and Sleep With Slander. She passed away on August 1, 1973 in Orange County, California, followed by Hubert in Riverside County in 1979.
