Arthur Joyce Lunel Cary (7 December 1888 – 29 March 1957) was an Irish novelist.
The curse of Cain and the mark of Cain are phrases that originated in the story of Adam and Eve in the Jewish and Christian Bibles.
 In the stories, if someone did something to harm Cain, the damage would come back sevenfold.
 Some interpretations view this as a physical mark, whereas other interpretations see the "mark" as a sign, and not as a physical marking on Cain himself.
 The King James Version of the Bible reads "set a mark upon Cain".
James Mallahan Cain (July 1, 1892 – October 27, 1977) was an American author and journalist.
 Cain vehemently opposed labeling, but he is usually associated with the hardboiled school of American crime fiction and is seen as one of the creators of the "roman noir".
 Several of his crime novels inspired successful movies.

 The film also stars Arundhati Roy, who was yet to write her first novel and win the Man Booker Prize, along with Barry John and Virendra Saxena.

The Horse's Mouth is a 1944 novel by Joyce Cary, the third in his "First Trilogy", whose first two books are "Herself Surprised" (1941) and "To Be A Pilgrim" (1942).
 "The Horse's Mouth" follows the adventures of Gulley Jimson, an artist who would exploit his friends and acquaintances to earn a quid, told from his point of view, just as the other books in the First Trilogy tell events from their central characters' different points of view.
 Cary's novel also uses Gulley's unique perspective to comment on the social and political events of the time.

 One of her daughters, Delia, went on to become a leading writer on Chinese social issues.
The Horse's Mouth is a 1958 film directed by Ronald Neame and filmed in Technicolor.
 Alec Guinness wrote the screenplay from the 1944 novel "The Horse's Mouth" by Joyce Cary, and also played the lead role of Gulley Jimson, a London artist.
Mister Johnson (1939) is a novel by Joyce Cary.
 It is the story of a young Nigerian who falls foul of the British colonial regime.
 Although the novel has a comic tone, the story itself is tragic.
 Joyce Cary has been quoted as saying that "Mister Johnson" was his favorite of his own books.
 "Mister Johnson" is often read in schools and has had a wide audience.
 It has been adapted as a play by Norman Rosten, and a film by Bruce Beresford.
 Chinua Achebe has said that "Mister Johnson" struck him as superficial and helped form his determination to write his own novels about Nigeria.
 Other critics have found Cary's portrayal of his main character patronizing and Johnson himself childish.
