The twist in Animal Farm, perhaps, as told (7)
I believe the answer is:
pigtail
'the twist' is the definition.
(pigtail is a kind of twist)
'animal farm perhaps as told' is the wordplay.
I cannot quite see how this works, but
'animal' could be 'pig' (I've seen this in other clues) and 'pig' is present in the answer.
The remaining letters 'tail' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'in' acts as a link.
(Other definitions for pigtail that I've seen before include "Naturally curly" , "Queue of hair" , "Plaited hair style" , "Schoolgirl's plait" , "Plait of hair at back of head" .)
