Literature
American author Zane Grey used the cartomantic meaning of playing cards in his novels. For example, in his book The Border Legion, he describes the character Joan Randle as an Ace of Hearts, after she "outwit[s] and outtalk[s] her would-be-seducer, outlaw Kells". The very same card is pinned by Kells to a tree, where he shoots at with many bullets, "every one of which touch[ing] the red heart and one of them...obliterat[ing] it", and then signs his name below. This foreshadows the climax described above. These uses of the ace of hearts by Grey utilize the many symbolic meanings of the card including intimidation, eroticism, and death.

Referring to the Jesuits, the author of The true history of Pope Joan says: "a certain prince of ours did compare unto them a game of cardes, in which the gamesters like loadem play and bring them forth last that are of most price, to beat downe the adverse play: or like the ace of hearts at Mawe (the game which is with us called Rumstich)". This is said to provide the answer to the origin of the card game Mawe.

In Tess of the D'Urbervilles by Thomas Hardy, the murder of the main villain is given away by a spot on the ceiling that "speedily grew as large as the palm of [Mrs. Brooks'] hand" and "[Mrs. Brooks] could perceive that it was red". The narrative goes on to say: "the oblong white ceiling, with this scarlet blot in the midst, had the appearance of a gigantic ace of hearts".
