"A secret so powerful it could change the fate of a nation—and only one man can find it."

The story begins with a daring robbery at the Château d'Ambrumésy, but the real mystery starts when a young, brilliant student named Isidore Beautrelet challenges the great Arsène Lupin. While the police are baffled, Beautrelet discovers a cryptic document mentioning "The Hollow Needle." This leads to an epic intellectual duel across France, culminating at the breathtaking cliffs of Étretat. Here, Lupin isn't just seeking gold; he has found the legendary hiding place of the French Monarchy's vast treasures—a secret fortress hidden inside a natural wonder.

A Rivalry for the Ages: In Beautrelet, Lupin finally finds a youthful mirror of himself. The boy's relentless logic forces Lupin to play his most sophisticated game yet. This novel transitions from a standard "whodunit" into a grand historical adventure, blending myth, architecture, and high-stakes deduction.

The Legend of the French Crown: Leblanc weaves real French history into the narrative, suggesting that figures like Caesar, Charlemagne, and Louis XIV all knew the secret of the Needle. Lupin becomes more than a burglar here; he becomes the "King of the World," the custodian of a legacy that dates back over a thousand years.

A Heartbreaking Climax: While filled with Lupin's trademark wit and daring escapes, The Hollow Needle is also known for its emotional depth. It features one of the most poignant moments in the series, revealing a rare glimpse into Lupin's heart and the price he pays for his life of shadows.
