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.
