The Sign of the Four: Character Quotations (AQA GCSE English Literature)

Revision Note

Sam Evans

Written by: Sam Evans

Reviewed by: Kate Lee

GCSE English Literature exam questions usually focus on a theme, a character or a relationship between two or more characters. Examiners reward responses that track the development of characters or themes through the novella. 

When revising, try to consider quotes in terms of their narrative effects — how characters are presented, what attitudes or relationships are presented and why these ideas have been shown to the reader. 

Revising quotations according to theme or character can help with this. We’ve included 12 The Sign of the Four quotes on this page, and organised them by the following characters:

  • Sherlock Holmes

  • Dr John Watson

  • Mary Morstan

  • Thaddeus Sholto

Examiner Tips and Tricks

Examiners say that the strongest responses explore characters in a particular context. What this means is that they want you to see the question, and extract, as a “stepping off point” from which to examine ideas in the novella. For example, you could discuss how and why Conan Doyle has presented Sherlock Holmes as an “extraordinary detective”. You could support this by exploring his relationships with Watson or by examining Watson’s role as narrator. 

To help you revise precise references, we’ve included a “key word or phrase” from every one of our longer The Sign of the Four quotes to help you keep your focus on the most important part.

Sherlock Holmes

“Some facts should be suppressed, or at least a just sense of proportion should be observed in treating them” - Sherlock Holmes, Chapter 1

Sherlock Holmes

Key word or phrase to memorise:  “a just sense of proportion”


What the quotation means: Holmes tells Watson that it is necessary to look beyond obvious facts in order to analytically reason

Theme: Justice and crime

  • Conan Doyle introduces his protagonist as an impartial, unemotional detective:

    • His detached manner of investigation is presented as rooted in objectivity

    • Here, he refers to a “just” attitude to information, suggestive of fairness

  • The “sense of proportion” he applies to justice is depicted later with Jonathan Small:

    • Holmes does not want Small punished for a crime he did not commit

“My case is, as I have told you, almost complete; but we must not err on the side of over-confidence” - Sherlock Holmes, Chapter 6

Illustration of Holmes as a man wearing a deerstalker hat and brown coat, smoking a pipe.
Sherlock Holmes

Key word or phrase to memorise:  “err” and “over-confidence”


What the quotation means: Holmes is keen to clarify all the details of his case before coming to any conclusions and tells Watson that it is a mistake to be excessively confident

Theme: Greed and obsession

  • One of the characteristics of Conan Doyle’s detective is his self-assuredness which can, at times, veer towards egotism:

    • Watson, as narrator, points out Holmes’ extreme nature throughout

    • Watson worries about his cocaine habit and low threshold for boredom

    • Holmes works hard and then becomes very lazy, Watson says

  • Conan Doyle’s detective is an enigma in that his work life and private life seem at odds:

    • Here, Holmes suggests that he carries out his work in a balanced way

    • He says here that being too confident about his case would be reckless

“There is nothing at all new to me in the latter part of your narrative, except that you brought your own rope. That I did not know”  - Sherlock Holmes, Chapter 12

Illustration of Holmes as a man wearing a deerstalker hat and brown coat, smoking a pipe.
Sherlock Holmes

Key word or phrase to memorise:   “your own rope” and “That I did not know”


What the quotation means: After Jonathan Small has finished telling them his strange story about cannibals and tribal dances, Holmes appears unsurprised, and simply says that he did not know about the rope

Theme: Colonialism

  • Holmes implies here that information he receives is seen only as part of his case:

    • His response to Small’s story about the “bloodthirsty” Tonga is detached

    • This may imply that he is less susceptible to fear-based discrimination

  • The chapter is called “The Strange Story of Jonathan Small” to highlight the unusual nature of what will be told:

    • This juxtaposes Holmes’ nonchalant response to Small’s account and creates dry humour

    • Holmes’ understated reply (litotes) is ironic in its focus on small details

Dr John Watson

“You know, too, what a black reaction comes upon you. Surely the game is hardly worth the candle” - Dr John Watson, Chapter 1

Illustration of Watson in a brown suit with a white shirt and black tie.
Dr John Watson

Key word or phrase to memorise:   “black reaction”


What the quotation means: Watson tells Holmes that when he takes cocaine his mood becomes dark, and that he thinks taking the drug is a gamble not worth the potential loss of his great powers

Theme: Greed and obsession

  • Conan Doyle introduces the intimate relationship between Watson and Holmes: 

    • It is made clear that Watson knows Holmes well

    • He discusses his cocaine habit, and that they both know its effect on him

  • Watson’s position as a doctor makes him more cautious than Holmes:

    • He suggests that Holmes is gambling with his talent by taking cocaine

    • The imagery of “black reaction” connotes to extreme bad moods

“There is something positively inhuman in you at times”  - Dr John Watson, Chapter 2

Illustration of Watson in a brown suit with a white shirt and black tie.
Dr John Watson

Key word or phrase to memorise:   “inhuman”

What the quotation means: Watson tells Holmes that his lack of emotion is not natural for a human being

Theme: Justice and crime

  • Watson’s character is a foil for Holmes:

    • This highlights ideas about human nature and justice

    • Watson is emotional, but Holmes believes this skews the truth 

  • Conan Doyle’s character, Watson, often comments on human nature:

    • Prior to this, he tells Holmes he is a “calculating-machine”, and an “automaton”

    • Watson believes emotion is natural, later referring to the spiritual and animalistic side of mankind

“‘Black or blue,’ said I, ‘they are in with me, and we all go together” - Dr John Watson, Chapter 12

Illustration of Watson in a brown suit with a white shirt and black tie.
Dr John Watson

Key word or phrase to memorise: “Black or blue” 


What the quotation means: Watson tells the captain and the major that, regardless of the colour of their skin, he must discuss plans with his “comrades”, Mahomet Singh, Abdullah Khan, and Dost Akbar

Theme: Colonialism

  • Conan Doyle’s characters often reflect racist attitudes which present ideas about imperialism:

    • Before Watson’s reply, the major comments, “What have three black fellows to do with our agreement?”

  • Watson’s response suggests he is impartial:

    • His alliterative remark emphasises that he does not discriminate by skin colour or race

    • He describes the men as “comrades”, meaning friends, implying a lack of prejudice

Mary Morstan 

“I can hardly imagine anything more strange, more utterly inexplicable, than the situation in which I find myself”  - Mary Morstan, Chapter 2

Illustration of Mary Morstan.
Mary Morstan

Key word or phrase to memorise:  “more strange, more utterly inexplicable” 


What the quotation means: When Mary Morstan visits Holmes and Watson, she is distressed about the whereabouts of her missing father

Theme: Justice and crime

  • Conan Doyle’s female character is presented as desperate about her situation:

    • Her distress is shown with anaphora

    • This emphasises her confusion

  • Her virtuous character is typical of gothic damsel in distress characterisations:

    • She is the catalyst for the mystery and the victim of a crime

    • She is presented as in dire need of the detective’s help

“‘What a pretty box!’ she said, stooping over it. ‘This is Indian work, I suppose?’” - Mary Morstan, Chapter 11

Illustration of the character Mary Morstan.
Mary Morstan

Key word or phrase to memorise:   “Indian work” 


What the quotation means: Mary Morstan remarks on the beauty of the metal box that they believe contains the treasure, and she suggests that the box comes from India

Theme: Colonialism

  • Mary Morstan is presented as disinterested in wealth and power:

    • Her description of the box suggests she is not preoccupied with its value

    • She appears more interested in its cultural history 

  • The treasure is a symbol of imperialism:

    • Here, Mary comments on the origin of the box (it belonged to an Indian prince)

    • She later remarks that the box “alone must be of some value”

    • The novella equates the British Empire with wealth and power

“It would be of the greatest interest to me” - Mary Morstan, Chapter 11

Illustration of the character Mary Morstan.
Mary Morstan

Key word or phrase to memorise:  “greatest interest” 


What the quotation means: When Mary Morstan says that she would be interested in seeing the treasure, Watson narrates that she says this simply to be respectful of the great lengths taken to find it

Theme: Greed and obsession

  • One of the novella’s key ideas is the conflict over ownership of the Agra treasure:

    • The obsessive quest for the treasure illustrates the capacity for greed

  • Mary’s great interest in the treasure, Watson says, is not one of “eagerness”:

    • He explains that she understands the sacrifices involved in its discovery

    • Indeed, Watson says he is relieved to be free of the “golden barrier”

    • This suggests the treasure is seen as a problem for Mary and Watson

Thaddeus Sholto 

“If my own servant could not believe my innocence, how could I hope to make it good before twelve foolish tradesmen in a jury-box?” - Thaddeus Sholto, Chapter 4

Illustration of Sholto as a man with a moustache, wearing a detailed turban adorned with a jewel and a patterned garment.
Thaddeus Sholto

Key word or phrase to memorise: “twelve foolish tradesmen in a jury box”


hat the quotation means: Sholto explains he is certain he will be arrested for his father’s murder, and adds that when his servant believed him responsible, he knew he had no chance of justice from the general public

Theme: Justice and crime

  • Conan Doyle’s novella depicts the fragility of the justice system in Victorian England:

    • Sholto implies that, as a gentleman of great wealth, he would be harshly judged by a working-class jury 

  • Sholto is certain that the “quarrel” and the “blow” the servant overhears would be enough evidence with which to convict him

  • This has the effect of confirming the need for a talented detective to deliver justice

“But let us have no outsiders,—no police or officials. We can settle everything satisfactorily among ourselves, without any interference” - Thaddeus Sholto, Chapter 4

Illustration of Sholto as a man with a moustache, wearing a detailed turban adorned with a jewel and a patterned garment.
Thaddeus Sholto

Key word or phrase to memorise: “no outsiders”


What the quotation means: Sholto is suspicious of authority and the police, and would prefer to solve the crime without their involvement

Theme: Justice and crime

  • In Victorian England, violent crime was rife, and generally went undetected:

    • Sholto portrays a distrustful attitude towards the criminal justice system

    • This highlights the pervasive desire for a detective like Sherlock Holmes

    • Holmes himself makes disparaging comments about the police as well

  • His request for no external involvement conveys a fearful, suspicious state of mind:

    • Conan Doyle illustrates his anxiety in the broken voice

    • His need to clarify (“no police or officials”) suggests his mistrust

“There, now! Didn’t I tell you!”  - Thaddeus Sholto, Chapter 6

Illustration of Sholto as a man with a moustache, wearing a detailed turban adorned with a jewel and a patterned garment.
Thaddeus Sholto

Key word or phrase to memorise: “Didn’t I tell you!” 


What the quotation means: Thaddeus Sholto exclaims his frustration at being arrested despite his innocence, as he had expected he would be

Theme: Justice and crime

  • The novella can be considered a challenge to the authorities in Victorian England:

    • As a result of rampant crime, upper class society felt unsafe

    • This is one of the reasons the detective series became so popular

  • Conan Doyle’s characters especially mistrust the efficacy of the police:

    • Sholto’s earlier suspicions that he would be accused are proven correct

    • The distress he feels at his arrest is conveyed in his indignant tone

    • The exclamatory words imply both his vindication and his anxiety
