The forced intro/ending with the descriptions of the scorpio and Africa felt out of place. These origins of the diamond smuggling operation were very disjointed from the rest of the story and would have been better left out. 

Oftentimes the action was very confusing and fumbled (esp when Bond is rescued) and again at the very end. Also seems

ridiculous that they would put Case in a different room than Bond in the first place due to the safety risk…

Some lines of the book were truly beautiful and memorable, “Marriage doesn’t add two people together, it subtracts one from the other” - iconic.
