The Hollow Needle written by Maurice Leblanc chronicles the exploits of gentleman thief Arsène Lupin. This was first published as a serial in the French magazine Je sais tout from November 1908 to May 1909, just like the first two volumes of Arsène Lupin's stories. With a few changes, it was published in June 1909 and the book has a plot of Isidore Beautrelet, a youthful but talented amateur investigator still in high school but who is ready to cause Arsène Lupin a lot of trouble, is Arsène Lupin's opponent this time. The second secret of Marie Antoinette and Alessandro Cagliostro, the secret wealth of the French monarchy, is given to Arsène Lupin by Josephine Balsamo in the book The Countess of Cagliostro. This is the world of Arsène Lupin (1924). Since the time of Julius Caesar, the Kings of France have been passing down a secret, which Arsène Lupin has now learned, in The Mystery of the Hollow Needle. The fabled needle has the most incredible riches one could conceive, including the money of the French monarchs and a collection of pearls, diamonds, sapphires, rubies, and queens' dowries.
