All Greed Quotes

“A wondrous subtle thing is love”
Dr WatsonChapter 5
FriendshipGreed

Context: Watson reflects on how quickly his bond with Mary has formed as they ride together through London at night.

Analysis

The lyrical inversion "A wondrous subtle thing is love" gives Watson's reflection an almost poetic, philosophical quality that sets him apart from Holmes's prosaic logic. The adjective "subtle" suggests love works quietly and instinctively, beyond rational analysis — something Holmes could never reduce to a science. Doyle presents genuine human connection as the warm counterpoint to the cold pursuit of the treasure.

Language Techniques:

InversionRomantic dictionFirst-person reflection

Exam Tip

Use for the love-versus-wealth theme. Watson gains a "treasure" (Mary) precisely as the literal treasure is lost — a deliberate contrast.

“The treasure is lost”
Mary MorstanChapter 11
GreedFriendship

Context: Mary responds calmly to the discovery that the Agra treasure box is empty.

Analysis

The flat, monosyllabic declarative "The treasure is lost" and her calm delivery show Mary values love and integrity over wealth. Her composure contrasts sharply with the violence and obsession the treasure has caused in others, marking her as morally admirable. Doyle uses the lost treasure to remove the social barrier of riches, freeing Watson to propose.

Language Techniques:

DeclarativeMonosyllablesIrony

Exam Tip

Key quote for the greed and love themes. The "loss" is really a gain — it clears the way for Watson and Mary's relationship.

“Then I say, 'Thank God,' too”
Mary MorstanChapter 11
FriendshipGreed

Context: Mary answers Watson's relief that the treasure is gone, accepting his love now that wealth no longer separates them.

Analysis

The echo of Watson's "Thank God" creates a moment of shared feeling, sealing their bond at the very instant the riches vanish. Her gratitude that the treasure is lost confirms that human love matters more to her than money or status. Doyle resolves the romance plot by privileging emotional wealth over material wealth.

Language Techniques:

Echo / repetitionIronyResolution

Exam Tip

Use for the novel's central contrast between love and money. Mary and Watson "gain" each other as the literal fortune is destroyed.

“It was an evil day for me when first I clapped eyes upon the merchant Achmet and had to do with the Agra treasure”
Jonathan SmallChapter 12
GreedJustice

Context: Small opens his long confession, looking back on how the treasure ruined his life.

Analysis

The ominous phrase "an evil day" frames the treasure as a curse from the outset, suggesting greed inevitably brings destruction. By beginning with regret, Small presents himself as a victim of fate rather than a mere criminal, partly winning the reader's sympathy. Doyle uses the treasure as a symbol of how imperial wealth corrupts everyone it touches.

Language Techniques:

ForeshadowingMotif of the curseConfessional tone

Exam Tip

A strong opening quote for the greed theme. The treasure as a "curse" links Small, Sholto and Achmet — all destroyed by it.

“a curse yet upon the man who owned it”
Jonathan SmallChapter 12
GreedEmpire and Colonialism

Context: Small reflects on how the Agra treasure brought ruin to every person who possessed it.

Analysis

The noun "curse" gives the treasure an almost supernatural, moral power to punish greed, tying material wealth to spiritual ruin. The universalising "the man who owned it" makes the warning apply to all, not just Small. Doyle critiques the lust for riches plundered from colonial India, implying such ill-gotten gains can never bring happiness.

Language Techniques:

SymbolismUniversalisingGothic motif

Exam Tip

Use to argue the treasure symbolises the corrupting effects of greed and empire. Note how every owner meets fear, guilt, slavery or death.

“Where is the justice that I should give it up to those who have never earned it?”
Jonathan SmallChapter 12
JusticeGreed

Context: Small protests that he has more right to the treasure than anyone, having suffered twenty years for it.

Analysis

The rhetorical question forcefully voices Small's sense of injustice, demanding the reader weigh his claim against the law. The verb "earned" pits his years of suffering against the unearned privilege of the Sholtos, blurring the line between villain and wronged man. Doyle complicates simple morality, suggesting justice and legality are not always the same thing.

Language Techniques:

Rhetorical questionEmotive verbMoral ambiguity

Exam Tip

Central to the justice theme. A sophisticated answer will argue Small is both criminal and victim, challenging the reader's sympathies.

“Whoever had lost a treasure, I knew that night that I had gained one”
Mary MorstanChapter 11
FriendshipGreed

Context: Watson reflects, after Mary accepts him, that her love is worth more than the lost Agra fortune.

Analysis

The pun on "treasure" sets the material fortune against Mary as an emotional "treasure", privileging love over money. The contrast between "lost" and "gained" turns the apparent disaster of the empty box into the novel's emotional triumph. Doyle resolves his plot by insisting that true wealth lies in human connection, not in plundered gold.

Language Techniques:

PunAntithesisResolution

Exam Tip

Though narrated by Watson, this captures Mary's worth in the love-versus-wealth theme. Strong material for a conclusion on greed and its rejection.

“An oasis of art in the howling desert of South London”
Thaddeus SholtoChapter 4
GreedDuality

Context: Thaddeus proudly describes his lavishly decorated apartment to his startled visitors.

Analysis

The contrasting metaphor of an "oasis of art" within a "howling desert" reveals Thaddeus's vanity and his sense of refined superiority over the surrounding city. The hyperbole exposes him as a comic, pretentious aesthete obsessed with luxury bought from the family's tainted wealth. Doyle satirises the affluent Victorian collector while linking material excess to the corrupting treasure.

Language Techniques:

MetaphorHyperboleSatire

Exam Tip

Use for the satirical presentation of wealth and gentility. Thaddeus's luxury is funded by the very treasure that destroys others.

“I am a great sufferer”
Thaddeus SholtoChapter 4
DualityGreed

Context: On learning Watson is a doctor, the hypochondriac Thaddeus immediately begins describing his many imagined ailments.

Analysis

The self-pitying declarative "I am a great sufferer" instantly establishes Thaddeus as a comic hypochondriac fixated on himself. The irony is sharp: he obsesses over imaginary illnesses while the real suffering of Small and others goes unnoticed. Doyle uses him as comic relief, but his self-absorption also satirises a wealthy class detached from genuine hardship.

Language Techniques:

DeclarativeComic ironyCharacterisation

Exam Tip

Use to discuss Thaddeus as comic relief and Doyle's satire of the idle rich. Contrast his trivial "suffering" with Small's twenty years' hard labour.

“Keep him out! For Christ's sake keep him out!”
Thaddeus SholtoChapter 4
JusticeGreed

Context: Thaddeus recalls his father Major Sholto's terrified dying words about the wooden-legged man, Jonathan Small.

Analysis

The desperate, repeated imperative "keep him out" conveys Major Sholto's guilt and terror at being hunted for the stolen treasure. The exclamatory religious appeal "For Christ's sake" heightens the gothic horror and signals a guilty conscience facing retribution. Doyle suggests that ill-gotten wealth brings fear and a kind of rough justice to those who betray others for it.

Language Techniques:

RepetitionImperativeGothic tone

Exam Tip

Reported by Thaddeus but originally Major Sholto's words — use for guilt, retribution and the treasure as a curse. Foreshadows Small's pursuit.

“I can do you justice”
Thaddeus SholtoChapter 4
JusticeGreed

Context: Thaddeus assures Mary he will give her the rightful share of the treasure his father withheld from her.

Analysis

The phrase "do you justice" presents Thaddeus as conscientious, eager to right his family's wrong against Mary, in contrast to his greedy brother Bartholomew. Yet his "justice" still depends on tainted treasure, complicating the idea of fair restitution. Doyle uses him to raise the novel's central question of who truly deserves the wealth, and whether stolen riches can ever bring justice.

Language Techniques:

Motif of justiceCharacterisationIrony

Exam Tip

Use for the justice and greed themes. Contrast conscientious Thaddeus with grasping Bartholomew, and with Small's competing claim to the treasure.
