The Letter for the King is set in a fictional medieval world. In the story, a youth's adventure is externalized in a search for a letter, which results in a discovery of their own persona.

In the night before his accolade and ascension to knighthood, which is traditionally spent as a nocturnal vigil in a small chapel, 16-year-old squire Tiuri, son of a famous knight in the realm of King Dagonaut, receives a desperate plea for help from a stranger knocking at the chapel door. Unable to refuse a call for help, he breaks the tradition and goes outside, where the stranger, an old man, hands him a sealed letter and begs him to deliver it to a knight clad in black armor and a white shield residing in a nearby forest inn. Tiuri agrees to deliver it, but upon arriving at the inn, he learns to his dismay that the knight he seeks has in the meantime been challenged by another black knight, this one with a red shield. Tracing the path the knights have taken into the forest, Tiuri finds the knight with the white shield dying, mortally wounded in a cowardly ambush. When the knight learns of Tiuri's possession of the letter, he charges him with delivering it to the neighbouring realm of the west, ruled by the wise King Unauwen, and to seek out a hermit named Menaures living in the mountains separating the two kingdoms, who would show him a secret way through the mountains. Bound by his sense of honor, Tiuri accepts the task and the ring the knight gives him in order to stress the importance of his mission, and remains with the knight until he dies.

Soon, however, Tiuri finds himself hunted by riders clad in red, the henchmen of the knight with the red shield, and is forced to flee for his life. In order to speed his progress, he claims the steed of the knight with the white shield, a formidable night-black destrier who accepts him as his new rider. He also finds himself chased by a quartet of knights in grey, who are eager to kill him for unknown reasons, and temporarily loses his horse to a band of robbers, but finds help with the childish but amicable forest-dweller Marius and the monks of a nearby monastery. He eventually makes his way to a castle named Mistrinaut, where he is found and imprisoned for execution by the Grey Knights, who (as it turns out later) were close friends of the knight with the white shield and believe Tiuri to be his murderer. However, Sigirdiwarth Rafox, the lord of Mistrinaut, and his daughter Lavinia supply Tiuri with weapons to save his life, and in the end Tiuri convinces the knights of his innocence and befriends them, especially their leader, Ristridin of the South, a famous wandering knight from Dagonaut's realm.´
