The two authors of “The Crevice” are well suited to writing a crime novel together. William J. Burns was director of the Bureau of Investigation, a predecessor to the FBI; a member of the Secret Service; founder of the eponymous detective agency; and author of true crime stories.
Isabel Ostrander was a prolific author of mystery novels and short stories from 1911 until her early death in 1924. She was successful enough to have been parodied in Agatha Christie’s 1920s collection of stories featuring the characters Tommy and Tuppence.
