Arsène Lupin versus Herlock Sholmes — Detective Analysis

Basic Information

Ratings Summary

This book is divided into two independent narrative arcs: "The Blonde Lady" (Chapters One through Six, approximately 80% of the book) and "The Jewish Lamp" (Chapters Seven and Eight, approximately 20%). The two arcs differ sharply in style: the former is a grand chase across Paris, while the latter is a tightly constructed indoor puzzle that delivers a moral reversal in its final moments to shock the reader.

Metric Rating Notes
Deducibility ⭐⭐⭐⭐ "The Blonde Lady" average convergence point approximately 65%; "The Jewish Lamp" average convergence point approximately 91%; overall weighted average approximately 71%
Fog Rating ⭐⭐⭐⭐ Multiple layers of false identities (Antoinette Bréhat / Madame de Réal / Clotilde Destange), a carefully engineered decoy substitution (the true versus false Madame Réal), a fabricated forced-entry scene (ladder marks), and a well-intentioned false confession (Alice's self-sacrifice) — four layers of fog, impenetrable

Synopsis

"The Blonde Lady" (Chapters One through Six)

Gerbois, a mathematics professor from Versailles, purchases a small writing desk at a secondhand shop and unwittingly becomes entangled in a wealth-seizure scheme meticulously engineered by Arsène Lupin — for inside the desk's secret drawer lies a lottery ticket worth one million francs. Lupin steals the desk and takes possession of the ticket, but finds himself in a bind: the ticket is in his hands, yet the legal claim belongs to Gerbois. The professor, meanwhile, is coerced into a compromise after his daughter Suzanne is "escorted away" by Lupin as a hostage, and ultimately receives half the prize money.

As this farce draws to a close, a mysterious "Blonde Lady" makes her entrance — first appearing in the bedroom of the murdered Baron d'Hautrec under the name "Antoinette Bréhat," then lying low in the company of the Countess de Crozon under the identity "Madame de Réal," orchestrating the theft of the blue diamond. Inspector Ganimard follows the trail but repeatedly passes within arm's reach of the "true Blonde Lady," only to arrest an innocent diamond broker who happens to share the same name.

While the Paris police stand helpless, the renowned English detective Herlock Sholmes is invited to France, and a ten-day battle of wits with Lupin begins. Sholmes discovers that three crime scenes — the apartment of lawyer Detinan (25 rue Clapeyron), the former residence of Baron d'Hautrec (134 avenue Henri-Martin), and the Château de Crozon — were all designed and built by the same architect, Lucien Destange, and that secret passages connecting adjacent buildings account for everything. Operating under a false name, Sholmes infiltrates Destange's library and finally identifies the true face of the Blonde Lady: Clotilde Destange, Destange's daughter and Lupin's longtime secret lover and accomplice.

When Sholmes uses Clotilde as a hostage, Lupin — disguised as a pre-booked taxi driver — calmly abducts both of them and ships Sholmes forcibly onto a vessel bound for England. Sholmes immediately tricks the captain into advancing his watch, disembarks early at Southampton, races back to Paris overnight, and, using an apartment address Lupin inadvertently revealed over the telephone, joins forces with Ganimard to mount a siege. Lupin is ultimately arrested, the blue diamond is retrieved (concealed in the hollow core of Lupin's walking stick), but Clotilde's identity is kept secret by Sholmes alone, in exchange for her freedom.

"The Jewish Lamp" (Chapters Seven and Eight)

Shortly after returning to Paris, Sholmes receives an invitation from Baron d'Imblevalle to investigate a peculiar theft: someone has broken into the baron's study from outside (ladder, cut window pane) and made off with an ancient Jewish lamp, whose hollow base concealed a gold chimera brooch set with rubies. The police investigation yields nothing, but Lupin sends a letter warning Sholmes not to get involved.

No sooner does Sholmes arrive in Paris than a mysterious young woman intercepts him, imploring him to abandon the investigation and return to England. Sholmes is unmoved. Forty minutes later, he sees through the fiction of "external forced entry": the ladder marks were made by a wooden block, the scratch marks on the balcony were made with sandpaper — the theft came from inside.

The clue is provided unwittingly by little Henriette: the governess Alice Demun habitually cuts letters from newspapers and pastes them into messages. Sholmes discovers the letters cut from a children's primer and reconstructs the corresponding code, tracing a secret channel of communication between Alice and the "Echo de France" personal advertisements column — her line of contact with Lupin. A second clue is a dropped taxi number, linking Alice to a second mysterious address.

A man suspected of being a blackmailer (going by the alias Bresson) kills himself as Sholmes closes in, and the case grows murkier. On the second night, another theft occurs — this time a diamond snuffbox and an opal necklace are also taken, and Wilson is wounded in the process.

In the end, Sholmes encounters Lupin again by the riverbank, disguised as a fishing old man, and the two play out a farcical yet brilliant final confrontation in a leaking boat, which sinks and sends both men swimming back to shore. Sholmes then reveals the full truth: it was Alice who stole the Jewish lamp, but her motive was to protect her mistress. The true injured party is the Baroness Suzanne d'Imblevalle — she had carelessly struck up an acquaintance with Bresson in society, and he had been blackmailing her with her private letters. Alice, to protect her, arranged the theft with Lupin's assistance to satisfy the blackmailer's demands; the second theft, which Bresson engineered independently, was his own act of greed.

The baron learns the truth and the marriage is damaged; Alice departs for England with Sholmes's assistance, while Lupin, already hidden on the same cross-channel steamer, serenely strikes a match.

4 40 rue Chalgrin (Lupin's gathering point) also bears the mark "Lucien Destange, architecte, 1877"; the adjacent No. 42 the same Chapter Five / approximately 75% Confirms the pattern by which Lupin selected his crime locations, and explains the garnet discovered in the cellar that night and the principle by which the two buildings are interconnected
5 The "M.B." account ledger in Destange's study cabinet lists 16 renovation addresses (including all three crime scenes) Chapter Five / approximately 80% The ledger reveals that "Maxime Bermond" is the alias Lupin used, and that he maintained a years-long conspiracy with Destange

Supporting Clues

# Clue Location (Chapter / Percentage) Notes
1 Ganimard searches Detinan's apartment for three days and nights without ever finding how Lupin made his exit Chapter One / approximately 17% Establishes that the "vanishing act" is no magic — there must be a physical passage; seeds the foreshadowing
2 The d'Hautrec case: the furniture had been rearranged and the scene cleaned — whoever did this must have been thoroughly familiar with the room's layout Chapter Two / approximately 27% Ganimard is the first to notice this, hinting at someone with intimate knowledge of the furnishings
3 At the Château de Crozon theft, the diamond is first stolen, then mysteriously placed in the Austrian consul Bleichen's tooth-powder tin — only someone with thorough knowledge of the château's structure could have entered and exited multiple times Chapter Two / approximately 35% The perpetrator has an intimate knowledge of the château's layout, something no outsider could manage
4 Sholmes discovers chalk marks on the floor of the former d'Hautrec residence: circles mark hidden panels, arrows indicate directions of movement, numbers indicate counts of floorboards — these are construction or operational instructions Lupin left in advance for his accomplices Chapter Three / approximately 50% Although this is a trap Lupin set to amuse himself, the marks themselves reveal the form in which the secret passages exist

False Clues

# Clue Location (Chapter / Percentage) Direction of Misdirection
1 Lupin and the Blonde Lady "vanish" from Detinan's apartment, leaving behind only the joke of Ganimard climbing the chimney for three days Chapter One / approximately 18% Directs the reader's attention toward the mystique of a "magic escape," distracting from the underlying physical mechanism — the connection between adjacent buildings
2 In the Château de Crozon case, all suspicion falls on Austrian consul Bleichen; the diamond is indeed found in his luggage Chapter Two / approximately 32% Diverts attention, leading the reader along with the police to conclude that Bleichen is the culprit
3 Lupin "locks" Sholmes and Wilson inside the former d'Hautrec residence and has a picnic basket sent to them Chapter Three / approximately 48% Pure mischief, but it causes the reader to concentrate attention on the "lock" mechanism, overlooking the possibility of the cellar connecting to the neighboring building

Truth Two: The True Identity of the Blonde Lady (whodunit)

Key Clues

# Clue Location (Chapter / Percentage) Notes
1 Ganimard notes that Antoinette Bréhat's (in the baron's case) hair exactly matches that of the Blonde Lady, and that the latter appeared under a new name (Madame de Réal) at Crozon the very day after the baron's murder Chapter Two / approximately 33% Ganimard's earliest intuition linking the two cases, though he fails to pursue it further
2 Ganimard finds two identical perfume bottles at Crozon — one from the Château de Crozon room, another from a Trouville hotel room — both bearing the same scent, corresponding to the "true Blonde Lady" Chapter Two / approximately 36% Confirms that "Antoinette Bréhat" and "Madame de Réal" are the same person; the chain of evidence is complete — but it points to her, not to Clotilde
3 Sholmes, working undercover in Destange's library, sees a mysterious figure searching the cabinet in the twilight — the figure is "Maxime Bermond," i.e., Lupin: Clotilde is present, clearly aware, yet entirely unperturbed Chapter Four / approximately 62% The tacit cooperation between Clotilde and Lupin is exposed for the first time; the reader may now suspect she is an accomplice
4 Sholmes follows a "veiled woman" to an apartment building, passes through a secret passage into an opulent boudoir, and the woman lifts her veil — Sholmes recognizes her as Clotilde Destange Chapter Five / approximately 75% Clue convergence point for this truth: the identity of the Blonde Lady is officially revealed
5 Sholmes cross-references four handwriting samples (Antoinette Bréhat's handwriting, an anonymous letter in the Crozon case, Madame de Réal's handwriting, and the Beaurivage hotel register) — all four match Chapter Two / approximately 38% Ganimard's chain of evidence is complete, but the final "confirmation" collapses when a witness misidentifies the person (a real diamond broker who happens to share the same name)

Supporting Clues

# Clue Location (Chapter / Percentage) Notes
1 Clotilde "rarely goes out, never leaves the house" in everyday life — this persona is precisely what covers her frequent movements Chapter Four / approximately 60% The reverse use of an alibi: others have established an impression that she "could not possibly have been out"
2 Sholmes eavesdrops on the conversation between Lupin and Clotilde in the study; she admits that she once killed for him, but that it occurred as an accident in self-defense Chapter Five / approximately 73% Confirms she was the perpetrator in the d'Hautrec case (the one who delivered the fatal blow), rather than a premeditated murderer

False Clues

# Clue Location (Chapter / Percentage) Direction of Misdirection
1 The "Madame Réal" arrested by Ganimard at the tearoom is a genuine blonde diamond broker who bears no resemblance whatsoever to Clotilde Chapter Two / approximately 38% Lupin knew in advance the line of pursuit Ganimard would follow and deliberately had the Blonde Lady use an alias that matched a real person's name, ensuring that investigators would come up empty
2 Ganimard, Detinan, and the Count de Crozon all refuse at the tearoom to identify Madame Réal as the woman they had seen, causing Sholmes's entire theory to collapse Chapter Two / approximately 40% The failure of a successful impersonation — the reader believes the "solution" has been negated and continues to suspect other directions

Truth Three: The Authenticity and Whereabouts of the Blue Diamond (howdunit)

Key Clues

# Clue Location (Chapter / Percentage) Notes
1 At the auction, the major bidder Herschmann receives an anonymous letter warning him that "the blue diamond brings misfortune" just as he is about to win the bidding, causing him to lose his focus and fail to secure it Chapter Two / approximately 28% Lupin covertly manipulates the auction results so that the Countess de Crozon wins the bid — this is one component of the entire plan, showing that the diamond's fate has been arranged from the start
2 Sholmes informs the Countess de Crozon on the train that the "blue diamond" in her possession is a synthetic fake; the genuine stone is already in Lupin's hands Chapter Three / approximately 47% Revelation of the false diamond; the reader learns of the genuine stone's existence, but not its location
3 During Lupin's initial conversation with Sholmes at the restaurant, he neither confirms nor denies anything, but responds with "Now that is a brilliant deduction," which amounts to tacit acknowledgment Chapter Three / approximately 48% Indirectly confirms that Sholmes's judgment is correct
4 Before being arrested, Lupin tells Sholmes: "I have no intention of handing over the blue diamond" — thereby emphasizing that the diamond is indeed on his person Chapter Six / approximately 93% Confirms possession
5 Sholmes proposes to exchange Clotilde's freedom for the blue diamond; Lupin agrees and instructs him to twist the iron ferrule at the base of the walking stick, extracting a wax pellet hidden inside the hollow core, within which the genuine diamond is concealed Chapter Six / approximately 97% The hiding place is revealed; the truth fully converges

Supporting Clues

# Clue Location (Chapter / Percentage) Notes
1 After the diamond is found, Bleichen insists the Count de Crozon planted it on him, producing a standoff in which each party maintains their own version — the police have no means whatsoever of determining whether the diamond is genuine Chapter Two / approximately 33% The elegance of Lupin's plan: a fake diamond and genuine accusations coexist simultaneously, leaving the authorities completely mired in confusion
2 When showing the Countess the "false diamond," Sholmes simultaneously explains the principle of synthetic diamond production (diamond powder compressed under high heat) Chapter Three / approximately 47% Provides the reader with a scientific background, making the claim of a "false diamond" more persuasive

False Clues

# Clue Location (Chapter / Percentage) Direction of Misdirection
1 The diamond is discovered in Bleichen's tooth-powder tin — conclusively and directly; everyone including the police believes it is the genuine diamond Chapter Two / approximately 30% The reader follows the official perspective in concluding "the case is solved, the diamond has been recovered," completely overlooking the possibility that the retrieved diamond might be a fake

"The Jewish Lamp" — Part Two

Truth Four: The True Mastermind Behind the Jewish Lamp Theft (whodunit + whydunit)

Key Clues

# Clue Location (Chapter / Percentage) Notes
1 Sholmes refutes the "external forced entry" hypothesis: the ladder holes are unevenly spaced (the two sets were made by the same wooden block), the scratch marks on the balcony were made with sandpaper, the wooden block is hidden in the flower bed — the theft was staged by someone inside the house Chapter Seven / approximately 15% The method of the crime is revealed: the thief is an insider, not an outsider
2 Little Henriette says that the governess Alice habitually cuts letters from newspapers and pastes them into "telegrams" to be sent out Chapter Seven / approximately 45% The first clue pointing to Alice, and also the tool she used to communicate with the outside
3 In the children's primer, the word "Saturday" has been cut out; nine further letters and three numbers are also missing; when arranged, they yield "REPOND Z—CH—237," pointing to advertisement No. 237 in the Echo de France personal column Chapter Seven / approximately 50% Confirms that Alice communicates with Lupin through newspaper advertisements, establishes the date of the crime (Saturday), and identifies the action code
4 Taxi number 8,279 (which fell out of Alice's small cloth bag) points to an outing recorded on Sunday morning: she traveled alone, carrying a "slender package," taking a taxi from near the park to the avenue des Ternes Chapter Seven / approximately 60% Confirms the route by which Alice transferred the stolen goods after the theft
5 Sholmes retrieves seven advertisements from the Echo de France that together reconstruct the entire history of the correspondence: Alice (code 540) soliciting Lupin's protection, providing the address, confirming the date of action; the final notice: "Understood. Will act Saturday. Sunday morning at the park" Chapter Eight / approximately 85% The communications record is fully reconstructed, confirming that Alice is the active planner (rather than someone acting under coercion)
6 The baron points out that the study door "was locked from the inside," so Alice could not have entered in the manner she claims — Alice's confession collapses on the factual level Chapter Eight / approximately 91% Clue convergence point for this truth: the reader can now deduce that what Alice says is false, and that the true insider must be someone else
7 Baroness Suzanne personally admits that the theft was planned against a background in which she was the victim, that Alice sacrificed herself for her, and that the private letters Bresson held were the origin of everything Chapter Eight / approximately 93% The full truth is revealed

Supporting Clues

# Clue Location (Chapter / Percentage) Notes
1 Lupin sends a letter in advance warning Sholmes not to intervene, with unusually intense phrasing — this is out of character with Lupin's usual manner, hinting that this time he is acting as a protector rather than a straightforward criminal Chapter Seven / approximately 5% Lupin plays the role of a "benevolent gray figure" in this case; a careful reader who notices this can suspect that his motive is not merely theft
2 Sholmes searches the kitchen, stables, and garden of the household and finds nothing — the thief had no need to enter any of these places, because she already lived in the house Chapter Seven / approximately 35% Eliminates outside personnel, narrows the range of internal suspects
3 A letter sent to Bresson (arriving only after his death) reads: "He accepts no compromise. He demands everything — the items from the first incident as well as the second. Otherwise he will take action" — Bresson's extortion never ceased even after items were returned Chapter Eight / approximately 87% Reveals that Bresson continued to apply pressure relentlessly, explaining why the theft Alice planned was insufficient to free the baroness, and also accounting for the motive behind the second theft

False Clues

# Clue Location (Chapter / Percentage) Direction of Misdirection
1 All the "physical evidence" of external forced entry: the ladder on the balcony, the cut window pane, the hole marks, the entrance near the Parc Monceau Chapter Seven / approximately 10% Leads the reader, along with the police and the baron, to believe this is a standard case of external burglary
2 Alice calmly "admits" in a self-confessing manner that she is the thief, but is unable to clarify the details regarding the lock Chapter Eight / approximately 90% Alice's well-intentioned lie is near-perfect; had the baron not exposed the contradiction in the lock, she would have almost succeeded in taking all responsibility upon herself

Truth Five: Bresson's Identity and the Second Theft (whodunit)

Key Clues

# Clue Location (Chapter / Percentage) Notes
1 "Bresson" rents an apartment on the avenue des Ternes under a false name, has lived there for approximately one month, moves about secretively, and his identity is unknown — clothing found in the same apartment bears different initials, indicating "Bresson" is not his true name Chapter Seven / approximately 58% First confirmation of the false-identity nature of Bresson
2 Sholmes witnesses Bresson going to the banks of the Seine at night to dispose of a package, but is unable to intercept him Chapter Seven / approximately 80% Reveals that Bresson is in the process of destroying (concealing) the items from the second theft
3 Bresson kills himself when the two men break down his door — this is not Lupin's style, nor would any of Lupin's people behave this way; it confirms that this individual belongs to an entirely different power Chapter Seven / approximately 85% Rules out the possibility that Bresson is one of Lupin's people
4 The letter received by Bresson after his death reveals that he was still pressuring a certain party to hand over "the items from both the first and second incidents simultaneously" — indicating that he was aware both thefts were connected to the same household Chapter Eight / approximately 87% Clearly establishes that the second theft was also Bresson's scheme, and not the work of Lupin
5 After the boat sinks and Sholmes swims to the riverbank, following hints Lupin unwittingly let slip on the boat, he locates the package Bresson hid on the riverbed, containing the Jewish lamp and other stolen items; the lamp's base does indeed contain the jewelry Chapter Eight / approximately 97% All stolen goods are recovered; Bresson's blackmail method (using the jewelry itself as collateral) is fully presented

False Clues

# Clue Location (Chapter / Percentage) Direction of Misdirection
1 Outside the apartment building, Sholmes notices a "beggar in disguise" who appears to be following him, leading him to assume this person is one of Bresson's accomplices or a surveillance agent Chapter Eight / approximately 82% This beggar is one of Lupin's informants, not one of Bresson's people — but the man's presence leads the reader to assume Bresson has been covertly setting up a defensive perimeter
2 The scene of the second theft (cut window pane, ladder) is almost identical to the first, making Sholmes's "inside job hypothesis" appear to have been refuted Chapter Seven / approximately 67% The second theft truly was an external forced entry, but both the reader and Sholmes are equally confused: does this overturn the deduction from the first theft? Sholmes insists it does not

Reasoning Path Reconstruction

"The Blonde Lady": A Reasoning Path from Architecture to Love

Reading Chapter One, the reader witnesses a lively comedy of property seizure, with no element of "mystery" visible — Lupin's identity, methods, and objectives are all transparent. The true mystery surfaces in Chapter Two: who is the Blonde Lady? How does she appear in and disappear from sealed rooms?

A careful reader, at Chapter Two (approximately 33%), who notices Ganimard's deduction — "Antoinette Bréhat's hair exactly matches the Blonde Lady's, and she appeared as 'Madame de Réal' the very day after the baron's murder" — should be able to deduce that these are the same person. But her specific identity remains a mystery.

First key node (approximately 42%): Sholmes reads the inscription "Destange, architecte, 1875" on a street corner. This is a small detail, easily overlooked, but for a reader with knowledge of architectural history, it is a nuclear detonation — three "impossible disappearances" suddenly acquire a single, unified physical explanation.

Second key node (approximately 53%): All three crime scenes (rue Clapeyron, avenue Henri-Martin, Château de Crozon) are confirmed to have been designed and built by the same Destange. The reader can now fully deduce the "how": the same architect, secret passages, connecting adjacent buildings, freedom of entry and exit.

Third key node (approximately 62%): Sholmes observes the private interaction between Clotilde and Lupin (operating as Maxime Bermond), realizing she is not merely a passive architect's daughter but an active accomplice. One further step remains: is she the Blonde Lady?

Convergence point (approximately 75%): Sholmes follows the veiled woman through the secret passage and lifts her veil — Clotilde Destange, the true face of the Blonde Lady officially revealed. All the mysteries converge here: she used her father's architectural blueprints to move through Paris; her love made her willing to become Lupin's shadow.

"The Jewish Lamp": A Reasoning Path from a Child's Words to Moral Truth

"The Jewish Lamp" is a "reverse" mystery: the surface crime is quickly seen through (15%), but the true questions — who? why? — lie buried until the very end.

First key node (approximately 15%): Sholmes dismantles the fake crime scene and confirms the thief is an insider. But who among those in the house? The baron, the baroness, the servants, the governess, the children.

Second key node (approximately 45%): Henriette's single remark — "the governess cuts out letters and pastes them into telegrams" — sounds like innocent childish chatter, but is in fact the key to the entire communications system. A careful reader, combining this with the clue of "who was it that first tried to stop Sholmes from investigating" (the mysterious young woman at the train station), should by now be able to reasonably suspect that Alice is not merely a nurse but someone implicated in the case.

Third key node (approximately 50%): The cut-out letters reconstruct "REPOND—ECHO—237." This is Alice's communications cipher, pointing to the scheme between her and Lupin.

Fourth key node (approximately 85%): Seven newspaper advertisements rebuild the entire history of the correspondence. Alice is the active supplicant ("540 Lady implores protection"), and the person she is appealing to is Lupin — she provided him with the address and confirmed the date of action.

Fifth key node (approximately 91%): The baron identifies the lock contradiction. Alice's confession collapses logically — she claims to have entered through the study door, but that door was locked from the inside, and on the night in question only the baron and baroness were inside the house.

Truth convergence (approximately 93%): The baroness's breakdown completes the final step. Only now does the reader understand that Alice is a protector, not a culprit; it is the baroness who possessed the "motive" — her past, her momentary credulity regarding Bresson, are the origin of everything. This is the most shattering moral reversal in the entire book: you believed you had found the "criminal," but she is in fact the most innocent person of all.

Supplementary Notes

Contrasting the Deductive Design of the Two Stories

The most compelling aspect of this book lies precisely in the fact that the deductive design strategies of the two narrative arcs are diametrically opposed:

Dimension "The Blonde Lady" "The Jewish Lamp"
Direction of solution Bottom-up (tracing events back to persons) Top-down (tracing persons back to motives)
Speed of convergence Gradual, multi-layered A sudden final reversal
Central technique Architecture as a tool of deduction Children's language as a conduit for clues
Greatest surprise The architect's secret passages The "true culprit" is the victim's protector
Moral register A symmetrical battle between geniuses An asymmetrical drama of sacrifice and love

Sholmes vs. Lupin: The Special Nature of This Confrontation

Leblanc does something in this book unprecedented in the history of detective fiction: he allows two of the strongest "adversaries" to share the same book's central narrative axis, yet never lets either side win a complete victory. Sholmes solves nearly every mystery, recovers the blue diamond, and arrests Lupin; but Lupin escapes after his arrest and makes Ganimard look ridiculous, Clotilde's identity is personally sealed by Sholmes, and Sholmes's true "final failure" comes in "The Jewish Lamp" — his investigation succeeds, yet it destroys a family, exposes the truth about Bresson, and leaves the baroness's secret with nowhere to hide. Lupin, meanwhile, casually observes in the final scene: "If you had not intervened, I could have tidied everything up for them myself, without destroying anything."

This is a profound literary irony: the detective's work is to reveal the truth, but sometimes the revelation of truth itself is the greatest harm.

The Writing Strategy Behind "Herlock Sholmes"

Leblanc's treatment of Conan Doyle's original character combines homage with playful mockery. The partner he assigns to Sholmes — Wilson (a surrogate for Watson) — is a far more comedic foil: not only does he come to grief through various misjudgments, but he is truly wounded on two separate occasions (a broken arm; a knife wound near the heart). Conan Doyle later reportedly requested that Leblanc change the character's name to avoid confusion among readers, which is why the book uses "Herlock Sholmes" rather than "Sherlock Holmes." Yet Leblanc's portrayal of Sholmes is by no means malicious mockery — he allows the English detective to display genuine intelligence and character; he simply confronts him with an adversary more complex than any criminal: a Lupin who possesses emotion, aesthetics, and a code of honor.

A Supplementary Note for Readers in Taiwan

In "The Blonde Lady," the historical background of the blue diamond is worth mentioning in the Chinese-language context: the blue diamond once belonged to the French royal family (in the story's setting it is connected to the "Duc d'Orléans" and an actress). The rarity of such a gemstone lies in the fact that its natural blue color derives from the special lattice structure of boron atoms within diamond crystal — it is one of the rarest colors a diamond can possess, and the historically famous "Hope Diamond" is perhaps the most celebrated example. Leblanc's use of this as a prop aptly reflects the fascination of French upper-class society of the time with aristocratic relics. For the reader, the blue diamond is a symbol of "calcified social hierarchy," and Lupin's act of "stealing from the rich to serve the clever" thereby carries even greater moral tension.
