A propos: I have often wondered what became of those nymphets later? In this wrought-iron world of criss-cross cause and effect, could it be that the hidden throb I stole from them did not affect their future? (Lolita - Vladimir Nabokov) What does wrought-iron world? wrought ˈiron noun [ uncountable ] long thin pieces of iron formed into shapes to make gates, fences etc (Longman Dictionary of Contemporary English) In this context it seems to mean 'industrialized world', right? I'm not sure if I see the significance of this in the context of this sentence. In what way is wrought-iron world related to 'criss-cross cause and effect'? Thank you in advance.
