Dramatist in posh close in resort (9)
I believe the answer is:
sophocles
'dramatist' is the definition.
(I've seen this before)
'posh close in resort' is the wordplay.
'in resort' indicates anagramming the letters.
'posh'+'close'='poshclose'
'poshclose' with letters rearranged gives 'SOPHOCLES'.
'in' is the link.
(Other definitions for sophocles that I've seen before include "Ancient Greek philosopher" , "Greek dramatist, author of Oedipus Rex" , "Greek dramatist (Antigone)" , "Classical versifier" , "One bringing charges" .)
