The talisman
(Book)

Encamped in the Holy Land, the crusaders are torn by the dissensions and jealousies of their leaders. The army's impotence is accentuated by the illness of their chief, Richard I of England. Meanwhile, a poor but doughty Scottish crusader known as Sir Kenneth, on a mission far from the camp, encounters a Saracen Emir. After an inconclusive combat, he strikes up a friendship with the Emir, who turns out to be Saladin himself. His alliance with the Moor will save him from more than one misfortune. Carrying a mystical talisman, Saladin enters the camp of the crusaders in disguise and cures Richard. When Sir Kenneth is later falsely dishonored, Saladin is in a position to intervene in his execution and receive him as his slave. Presenting the knight with the talisman, Saladin then arranges a plot for Sir Kenneth's vindication.
