  ## Plot summary
  
  Arsène 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 Arsène Lupin a big headache. In the Arsène 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 Arsène 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 Arsène 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 Château 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 château 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 Arsène Lupin, known also under the name of Louis Valméras, has hidden himself.
  
  ## Sequels
  
  A direct sequel to this novel, featuring Lupin against La Griffe, is the novel Le second visage d'Arsène Lupin by Boileau-Narcejac in 1975.
  
  ## In the popular media
  
  In January 2021, Netflix began streaming the Lupin (TV series) of five episodes; they take place in current times and feature fictional master thief Assane Diop. According to Rolling Stone (magazine), "both the show and the character of Assane take their inspiration from Arsène Lupin ... [the main character is given] a Lupin novel at a formative age, and Assane treats the Lupin stories as his own personal Bible [while performing] "spectacular crimes". The fifth episode of the series was filmed in and around the commune of Étretat where Maurice Leblanc owned a home which is now the Clos Lupin Museum.
