Edition details
Book Summary
A schoolboy detective, Isidore Beautrelet, matches wits with the gentleman-burglar Arsène Lupin in a high-stakes chase across France. The pursuit leads to the discovery of a centuries-old secret—the Hollow Needle—a hidden sanctuary and treasure vault used by French kings, now claimed by Lupin.
After a burglary and murder at the Château d'Ambrumésy, schoolboy detective Isidore Beautrelet deduces that the legendary Arsène Lupin is alive and behind the crime. Lupin, having faked his death and abducted Raymonde de Saint-Véran, taunts Beautrelet with clues. Beautrelet follows a trail of historical documents revealing the secret of the Hollow Needle—a hidden cavity within the Étretat cliff that has served as a royal treasure vault since the time of Louis XIV. Lupin, disguised as the helpful Valméras, manipulates Beautrelet's investigation to secure his marriage to Raymonde. In a final confrontation inside the Needle, Lupin shows Beautrelet the immense treasures of the kings of France, explaining how he decoded the ancient secret. The novel ends with Lupin escaping, leaving Beautrelet to ponder the nature of power, legacy, and the thin line between crime and genius.

Follow the arc while readingIsidore Beautrelet
Beautrelet is a Lycée Janson-de-Sailly pupil, industrious and of exemplary behavior, whose reputation as an observer whom nothing escapes has reached the examining magistrate before he ever appears in the case. He carries himself with a bow to Ganimard as to a colleague, yet answers questions with disarming humility, insisting he knows nothing while quietly producing the one precise point everyone else missed. His gift is deduction stripped of extraneous comment, and it is this that turns a baffling burglary into a thread leading toward the Hollow Needle.
Arsène Lupin
Lupin moves through the story as a myth that reality cannot account for, a man whose infinite resources still require a sure retreat and the certainty of impunity. The Needle supplies both: a royal strongroom of Merovingian gold, crown-pieces, and stolen masterpieces, rebuilt by his own hands when he found its tunnel collapsing into the sea. Without it he is a character in a novel; with it he becomes simply a man wielding an extraordinary weapon, and the mystery of his power becomes the mystery of the book.
Inspector Ganimard
Ganimard is the professional whose place, the magistrate insists, is in the room whenever Beautrelet speaks, though the inspector would clearly rather be elsewhere. He is nonplussed by the boy's low bow, skeptical of armchair deduction, and driven by the plain policeman's instinct to break down doors rather than reason through them. His dogged pursuit of Lupin supplies the story's bass note of official pursuit, against which Beautrelet's leaps of insight look either brilliant or absurd.
Raymonde de Saint-Véran
Raymonde is a guest in the de Gesvres household, quick to rise and look out when a noise wakes her, and steady enough to think through what she sees even as her cousin Suzanne clings to her in fear. She weighs calling for help against the danger to Suzanne's father, and it is her finger on the bell that finally breaks the silence. Her testimony about the man by the fountain and the ladder at the balcony becomes one of the earliest fixed points in a case that will not stay fixed.
Comte de Gesvres
The Comte de Gesvres presides over a country house of lawns, thickets, and the tragic ruins of an old abbey, a setting whose peace is broken by intruders and a shot. His room adjoins the boudoir where the thieves worked, and his daughter's fear for him shapes the household's first, hesitant response. Around his stolen property the investigation assembles, and his name becomes the doorway through which Beautrelet and Ganimard enter the larger riddle of the Needle.
