Lenore Glen Offord (1905-1991) was a writer and critic who wrote mysteries set in and around San Francisco in the 1940s and 1950s. She was the mystery reviewer for the San Francisco Chronicle for over thirty years (she took over for Anthony Boucher during the war), winning an Edgar award for Outstanding Criticism in 1952. She was also an avid Sherlock Holmes fan, and the first female member of the literary society The Baker Street Irregulars. Offord published twelve novels, eight of them mysteries that regularly feature startlingly modern female protagonists. She was, critic Sarah Weinman writes, "a writer of utterly delightful tales that mixed a strong sense of fair play, a wry wit, and a shrewd sense of domestic relationships."
