In this Imagination Station adventure Patrick and Beth find themselves as guests in a beautiful castle in 15th century England. Through a series of events, the steward of Lord Darkthorn’s castle finds the cousins with three artifacts collected in their previous adventures: the stone, the cup, and the golden tablet. They are accused of being thieves and locked in jail. Beth escapes and discovers the identity of the real thief, leading to a jousting contest with a surprising outcome. Set during the War of the Roses in England, Revenge of the Red Knight will teach readers about the Crusades, the integrity of knights and the vows they took, and why men would choose to risk their lives to fight for Christianity.
