In this film Bond faces off against what would be the first in a long line of burly blonde Aryan looking henchmen in the form of Donald "Red" Grant. A little less than 50 years after this film was made the world was given a blonde James Bond (in contrast to the usual dark haired Bonds) in Daniel Craig.
Moral Event Horizon: For most of the film, Grant appears to simply be a professional doing his work. Then he and Bond finally meet and we see what a twisted bastard he really is.
"My orders are to kill you and deliver the Lektor. How I do it's my business. It'll be slow and painful. The first shot won't kill you. Nor the second. Nor even the third. Not until you crawl over here and kiss my foot!"
Nausea Fuel: Fleming's extremely detailed description of what it feels like to be shot in the heart.
Tear Jerker: The chapter "Out of Danger," where Bond has to break the news of Kerim's death to his son and M.
Values Dissonance: Kerim's kidnapping, imprisoning, and attempting to brainwash a woman into loving him in his backstory is portrayed as a mere "youthful indiscretion" that the Service quickly straightened out of him, rather than the serious crime it would be extremely difficult to redeem oneself from that it would be seen as today. This can definitely hamper modern readers' sympathy for Kerim.
Bond and Tatiana telling Domestic Abuse jokes. Even as playful banter it's doubtful this would fly today outside of a Black Comedy.
