Avery Hopwood & Mary Roberts Rinehart 
Bat 

Known as the queen of the whodunits in her time, mystery writer Mary Roberts Rinehart created some fascinating sleuths and master criminals. One of her most widely recognized creations was the costumed arch-villain and criminal mastermind known as The Bat. This tale served as an introduction to the character, and was later transformed into a play bearing the same title.
