II: Isidore Beautrelet, Sixth-Form Schoolboy
Isidore Beautrelet, a schoolboy detective, is celebrated by the press for his insights into the Lupin case. He plans to investigate during the Whitsuntide holidays, but on the journey to Dieppe he receives a threatening note. Upon arrival, he learns of the burglary at the Château d'Ambrumésy and the kidnapping of Mlle. de Saint-Véran. He examines a cryptic document found at the scene. Later, he is captured by Ganimard but released by M. Filleul, who then questions him about his deductions. Beautrelet argues that since a theft occurred but nothing was reported missing, the stolen items must have been replaced by exact duplicates.
Chapter 3
The Corpse
Isidore Beautrelet reveals that the chapel's statues and high altar are plaster casts, proving Lupin's gang stole the originals. He deduces the existence of a hidden crypt beneath the chapel where Lupin's body lies. After breaking through the altar, they discover the crypt and descend to find the corpse.
Chapter 4
IV: Face to Face
Five weeks after the Ambrumésy mystery, the public is obsessed with the case, believing Arsène Lupin dead. Isidore Beautrelet, recovering from his wound, has deduced the truth: Lupin is alive, having been nursed by Mlle. de Saint-Véran, whom he later abducted. In a tense confrontation, Beautrelet reveals his plan to publish an article exposing Lupin's survival and the staged death. Lupin threatens to kidnap Beautrelet's father, but Beautrelet counters that his father is safely hidden. The chapter ends with a stalemate between the two rivals.
Chapter 5
On the Track
Isidore Beautrelet learns of his father's mysterious disappearance from the naval arsenal at Cherbourg, despite tight security. He receives Lupin's letter confessing his love for Mlle. de Saint-Véran and seeking peace. Beautrelet investigates, following Gaffer Charel, a witness who may have seen the prisoner, but finds the old man's memory has been tampered with. He then shadows a man watching Charel, hoping to find the hidden castle where his father is held.
Chapter 6
VI: An Historic Secret
This chapter reveals the historical secret behind the Hollow Needle, tracing its origins from Louis XIV through the Man with the Iron Mask, Joan of Arc, and the French Revolution. Lupin's letter explains how he deciphered the ancient document and set a trap for Beautrelet. Meanwhile, Raymonde de Saint-Véran and Beautrelet's father are freed, Lupin is publicly humiliated, and the engagement of Louis Valméras and Raymonde is announced.
Chapter 7
VII: The Treatise of the Needle
Isidore Beautrelet, determined to continue his war against Arsène Lupin, re-examines the mystery of the Hollow Needle. He investigates the murder of a captain of the guards and traces the lineage of M. de Larbeyrie. With the help of M. Massiban, he learns of a suppressed passage by Voltaire linking Louis XIV to the affair. Beautrelet then visits the Musée Carnavalet, where he discovers Marie Antoinette's book of hours. Inside, he finds a note from the queen to Fersen, dated 16 October 1793, but also signed by Arsène Lupin, confirming that Lupin had already taken the crucial document. Despite this setback, Beautrelet remains confident that the secret can be uncovered.
Chapter 8
From Caesar to Lupin
Beautrelet, inspired by Lupin's boast that it took him ten days to solve the mystery of the Hollow Needle, decides to abandon direct pursuit and instead focus solely on the pamphlet and the document that Lupin used. He isolates himself in Paris to think, and after thirteen days deduces that all historical events linked to the secret occurred within the old kingdom of Neustria (Normandy). He narrows the search to the Cauchois triangle between Rouen, Dieppe, and Le Havre, and retraces Lupin's steps along the Seine. Disguised, he encounters a horse-dealer who recognizes him—revealing himself as a fellow pursuer of the secret.
Chapter 9
IX: Open, Sesame!
Beautrelet discovers that the Étretat Needle is hollow, a secret sanctuary and treasure vault used by kings and now by Arsène Lupin. He locates the hidden entrance and observes Lupin's men moving goods out at night. He then meets Inspector Ganimard, who reveals that the government considers the Needle a state secret of military importance. They plan an assault for the next day at high tide, using a dozen fishing smacks and a torpedo boat to block escape by sea. Despite the plan, Beautrelet is anxious, knowing Lupin may already have fled.
Chapter 10
X: The Treasures of the Kings of France
Beautrelet is brought to the Hollow Needle and meets Lupin, who reveals himself as Valméras, the very man who had assisted Beautrelet in his hunt for Lupin. Lupin explains how he used Beautrelet's pursuit to marry Raymonde de Saint-Véran. Lupin shows Beautrelet the treasure chambers of the Needle, including the empty bowls once filled by French kings and the intact jewel chest.
