Indiana Jones and the Last Crusade was the focus of a "Young Indiana Jones" series of young adult novels that began in 1990; by the ninth novel, the series had become a tie-in to the television show. German author Wolfgang Hohlbein revisited the 1912 prologue in one of his novels, in which Indiana encounters the lead grave robber—whom Hohlbein christens Jake—in 1943. The film's ending begins the 1995 comic series "Indiana Jones and the Spear of Destiny", which moves forward to depict Indiana and his father searching for the Holy Lance in Ireland in 1945. Spielberg intended to have Connery cameo as Henry in "Kingdom of
Indiana Jones (franchise) fact, rather than myth." MacGregor's favorite book was "The Seven Veils", which featured real-life explorer Percy Fawcett and the death of Indiana's wife, Deirdre Campbell. Martin Caidin wrote the next two novels in Bantam's series, "Indiana Jones and the Sky Pirates" and "Indiana Jones and the White Witch". These feature Gale Parker as Indiana's sidekick; they introduced afterwords to the series, regarding each novel's historical context. Caidin became ill, so Max McCoy took over in 1995 and wrote the final four novels: "Indiana Jones and the Philosopher's Stone", "Indiana Jones and the Dinosaur Eggs", "Indiana Jones and the Hollow Earth",
