The Crevice

The two authors of "The Crevice" are about as well-suited to writing crime novels together as any pair in the world.

William J. Burns was born in had served as the director of the Bureau of Investigation, which was a predecessor to the FBI, and as a member of the Secret Service before founding the eponymous detective agency. He often published "true crime" stories that were based on his cases.

Isabel Ostrander was born in 1883. She was a prolific author of mystery novels and short stories from 1911 until her early death in 1924. Ostrander was successful enough to have been parodied by Agatha Christie in her 1920s collection of stories featuring the characters Tommy and Tuppence.

"The Crevice" is the only known collaboration of this dynamic duo.
