Complain as storyteller returning (4)
I believe the answer is:
rail
'complain' is the definition.
(I know that rail is a type of complain)
'storyteller returning' is the wordplay.
'storyteller' becomes 'liar' (telling stories can mean lying).
'returning' is a reversal indicator.
'liar' in reverse letter order is 'RAIL'.
'as' is the link.
(Other definitions for rail that I've seen before include "Barrier around lair" , "British --; picture --" , "transport system" , "Scold, berate" , "Bar of track or fence" .)
