Famous Dickensian turn of events (5)
I believe the answer is:
twist
This clue is a double definition.
'famous dickensian' is the first definition.
(Charles Dickens character Oliver Twist)
'turn of events' is the second definition.
('twist' can be a synonym of 'turn of events')
(Other definitions for twist that I've seen before include "Character demanding more" , "Wind spirally" , "Request for another card" , "See Oliver" , "Twirl" .)
