The Heads of Cerberus was published in five parts in The Thrill Book beginning with the August 15, 1919 issue.

Francis Stevens was the pen-name of Gertrude Barrows Bennett (1883-1948). Bennett has been credited as having “the best claim at creating the new genre of dark fantasy”.

Bennett was the first major female writer of fantasy and science fiction in the United States, and has been called the most important female fantasy writer between Mary Wollstonecraft Shelley and C.L. Moore. It has been said that she influenced both H.P. Lovecraft and A. Merritt, both of whom “emulated Bennett’s earlier style and themes.”
