"expression of extraordinary concentration upon his clear-cut, hawklike features"
zoomorphism
sharp, observant, predator
seeks the truth, wants to find criminals (like chasing after prey)
"state your case" said he, in brisk, business tones
seeks facts
ignores everything else - feelings, appearance of MM
"Is she?... I did not observe" (in response to JW "very attractive woman")
opposite reaction to JW
SH not focused on appearance
"You really are an automaton,- a calculating machine!" (JW)
like a machine - designed for purpose, one input needed to function, no emotions
"A client is to me a mere unit, a factor in a problem"
depersonalise, dehumanise the case
detach emotions
MM's feelings and looks are not important
"his clear-cut, hawk-like features" - JW
JW idolises SH
animal imagery - predator-prey
SH is portrayed as a hawk, a predator, dominate the animal kingdom, top of the food chain therefore most powerful and skillful
"you really are an automaton - a calculating machine!"
machine - made for a purpose
SH does not act human
Holmes is portrayed as meticulous, methodical, intrigued, yet also detached. He only cares about the case, detaching from emotions and therefore is unaffected by Mary's appearance
