Sad after stories, goes to bed? (4,4)
I believe the answer is:
lies down
'goes to bed?' is the definition.
(lies on a bed)
'sad after stories' is the wordplay.
'sad' becomes 'down' (down can mean sad or unhappy).
'after' is a charade indicator (letters next to each other).
'stories' becomes 'lies' (to tell stories can mean to lie).
'down' after 'lies' is 'LIES DOWN'.
(Other definitions for lies down that I've seen before include "Relaxes" , "given evidence veracity levels are rising?" .)
