You will be given a summary of a story. You need to create a question that can be answered from the story. You can create a question about characters, events, facts and beliefs, etc. Your question should be specific, try not to use pronouns instead of full names. As the stories are sometimes movie plots, they will contain actor names in parentheses. You should not use those names. Only use character names. Try to ask a question about all parts of the plot, not just the beginning.

Ars ne Lupin is opposed this time by Isidore Beautrelet, a young but gifted amateur detective, who is still in high school but who is poised to give Ars ne Lupin a big headache. In the Ars ne Lupin universe, the Hollow Needle is the second secret of Marie Antoinette and Alessandro Cagliostro, the hidden fortune of the kings of France, as revealed to Ars ne Lupin by Josephine Balsamo in the novel The Countess of Cagliostro (1924). The Mystery of the Hollow Needle hides a secret that the Kings of France have been handing down since the time of Julius Caesar... and now Ars ne Lupin has mastered it. The legendary needle contains the most fabulous treasure ever imagined, a collection of queens' dowries, pearls, rubies, sapphires and diamonds... the fortune of the kings of France.
When Isidore Beautrelet discovers the Ch teau de l'Aiguille in the department of Creuse, he thinks that he has found the solution to the riddle ("l'Aiguille Creuse" being French for "The Hollow Needle", and also the French title of the novel). However, he did not realize that the ch teau was built by Louis XIV, the king of France, to put people off the track of a needle in Normandy, near the town of Le Havre, where Ars ne Lupin, known also under the name of Louis Valm ras, has hidden himself.
Who is Louis Valmeras?
