Play a hit, newsletter misrepresented (3,7,4)
I believe the answer is:
the winters tale
'play' is the definition.
(I've seen this before)
'a hit newsletter misrepresented' is the wordplay.
'misrepresented' indicates an anagram.
'a'+'hit'+'newsletter'='ahitnewsletter'
'ahitnewsletter' is an anagram of 'THE WINTERS TALE'.
(Other definitions for the winters tale that I've seen before include "entertainment" , "The Bard's work" , "Play" .)
