Indiana Jones and the Last Crusade (Indiana Jones #3)

The time is the 1930s.

Indiana Jones had always managed to get into enough trouble on his own. But this time, he finds himself in the deadliest situation imaginable -- he must rescue his father, eminent professor Dr. Henry Jones, from the Nazis' clutches to keep them from discovering secret information only Dr. Jones possesses.

The perilous race is on -- to recover the most extraordinary ancient relic of all time -- and to prevent the Nazis and Dr. Jones's devious rivals from finding it first!
