Unforeseen development for Oliver? (5)
I believe the answer is:
twist
This might be a double definition.
'unforeseen development' is the first definition.
'twist' can be an answer for 'development' (twist is a kind of development). I am not certain of the 'unforeseen' bit.
'oliver?' is the second definition.
(as in Oliver Twist)
'for' acts as a link.
Can you help me to learn more?
(Other definitions for twist that I've seen before include "Character demanding more" , "Wind round - distort" , "quirk?" , "Dance; defraud" , "Embellishment to plot" .)
