John Silence (also known as John Silence: Physician Extraordinary) is a collection of supernatural short stories by English journalist and author Algernon Blackwood, first published in 1908. They are considered early examples of the occult detective subgenre, and went on to greatly influence other characters such as William Hope Hodgson's better known Carnacki.
Silence is a physician who, thanks to his independent wealth, takes his cases free of charge. Having undergone psychic training, he investigates matters rooted in supernatural causes.
Silence appears in the following tales:
Ancient Sorceries served as partial inspiration for the classic horror film Cat People.
Ancient Sorceries was adapted as the sixth episode of series two of Tales of Mystery, an ITV anthology series adapting Blackwood's stories. Broadcast on August 8, 1962, the episode did not feature the character of Silence.
The CBS anthology series Escape adapted Ancient Sorceries. Two broadcasts were aired in February 1948 for the east and west coasts. Silence did not appear.
Four of the stories were dramatised by Sheila Hodgson for BBC Radio 4 from August 1974 to October 1975: The Camp of the Dog, The Nemesis of Fire, Secret Worship, and The Empty Sleeve. All starred Malcolm Hayes as Silence.
