The end of acts in play touring old city (8)
I believe the answer is:
curtains
'the end' is the definition.
('curtains' can mean someone's end or demise)
'acts in play touring old city' is the wordplay.
'play' indicates anagramming the letters.
'touring' is an insertion indicator (touring can mean going round).
'old city' becomes 'ur' (ancient city state).
'acts'+'in'='actsin'
'actsin' is an anagram of 'ctains'.
'ctains' enclosing 'ur' is 'CURTAINS'.
'of' acts as a link.
(Other definitions for curtains that I've seen before include "Hanging cloths" , "Death (slang)" , "for Windows" , "Window drapes in slangy ending" , "Hanging drapes" .)
