Publication history
Golden Age version
The Spectre debuted in More Fun Comics #52 (February 1940) when hard-boiled cop Jim Corrigan, on his way with his fiancée Clarice to their engagement party, is murdered by thugs who stuff him into a barrel filled with cement and which is then thrown into a body of water. Corrigan's spirit is refused entering into the afterlife, and is instead sent back to Earth by an entity referred to only as "the Voice" to eliminate evil.
