Charlotte Armstrong (1905-1969) was an Edgar Award-winning American author of mystery short stories and novels. Born and raised in the mining region of Michigan’s Upper Peninsula, she moved to New York and received a B.A. degree from Barnard in 1925. She had two plays produced on Broadway but neither was successful, so she turned to writing mystery fiction. Several of her novels were adapted for film, including The Unsuspected andThe Chocolate Cobweb.
