The eight Doctor Satan stories by Paul Ernst appeared in Weird Tales in 1935 and 1936. Doctor Satan, an enormously wealthy man, tired of all the thrills that money can buy, turned to crime and became a cold-blooded monster. He employs both scientific and occult knowledge to commit fiendish and sinister acts of evil, and spectacularly gruesome murders.

Ascott Keane, strangest of detectives, with an equal knowledge of science and the occult, battles against the diabolical Doctor Satan to save society.
