""You know the doctor's ways, sir" replied Poole, "and how he shuts himself up. Well he's shut up again in the cabinet; and I don't like it, sir - I wish I may die if I like it. Mr. Utterson, sir, I'm afraid.""
repetition of "sir" reminds of the differing class statuses, the repetition is also used to convey Poole's panic
When Poole mentions how Jekyll shuts himself up, this contrasts how he was open before
The hyperbole of "I wish I may die if I like it" reveals the extent of Poole's horror
"mopped his brow with a red pockethandkerchief"
Red has connotations to danger
"strangling anguish; for his face was white and his voice... harsh and broken"
Imagery of terror and death
"[Poole] knocked in a guarded manner"
Being cautious
"Now sir... you come as gently as you can. I want you to hear and I don't want you to be heard... if by any chance he was to ask you in, don't go"
Rigid Victorian class sytem
Poole subverts this using imperatives
Natural order of Victorian society is being upturned
"him, or it; whatever it is that lives in the cabinet, has been crying night and day for some sort of medicine and cannot get it to his mind"
Poole uses the ambiguous language of "him or it" to describe what is hiding in the cabinet (it's Hyde), he is unsure if whatever is inside is human or not, he suggests this by ammending "him" to "it"
"he was at the far end of the room digging among the crates. He looked up when I came in, gave a kind of cry and whipped upstairs"
Digging is zoomorphic verb, zoomorphism is common when describing Hyde, suggests he is a scavenger, returning to prehistoric man
Whipped suggests animalistic traits, common with Hyde, going up with animalistic speeds
a kind of cry suggests it is not human, a creature relating to Hyde
"the hair stood upon my head like quills"
Zoomorphic simile - fear from seeing Hyde, common trope
Hyde's animalistic nature is infectious
"why did he cry out like a rat"
Simile - compares Hyde to vermin
""My master... is a tall fine build of a man and this was more of a dwarf""
Dwarf is embodiment of Victorian anxieties about evolution, it represents physical degeneration
""Well when that masked thing like a monkey jumped from among the chemicals and whipped into the cabinet, it went down my spine like ice""
Poole uses ambiguous language to describe Hyde, "thing" is ambiguous relating to Hyde's inhuman nature, being supernatural
The simile compares Hyde to a monkey relating to Darwinism in an animalistic way
