The Man Who Could Work Miracles (1936)

George McWhirter Fotheringay, while vigorously asserting the impossibility of miracles, suddenly discovers that he can perform them. After being thrown out of a bar for what is thought to be a trick, he tests his powers and eventually sends a policeman to Hades by accident. Worried, he sends the police officer to San Francisco, and seeks advice from the local clergyman, Mr Maydig. Maydig, after having Fotheringay's powers demonstrated to him, quickly planning for reform of the world by means of miracle, but eventually Fotheringay orders a miracle which, due to clumsy wording, backfires. He relinquishes his power and returns to the time before he had it.
