In this book you will meet the famous adventurer Indiana Jones again. This time Indy went to the south of France to the ancient city of the knights of Aigu-Mortes. He just wanted to acquire a medieval manuscript for his father, Professor Jones. Could he have thought that the young scholar-historian Thornton, a typical “bookworm” and bore, with whom Indy went on this journey, would drag him into such dizzying and dangerous events? Suffice it to say that Indy ends up in a real gypsy camp and comes face to face with the man in the iron mask.
