'where' is the definition.
The definition suggests a singular noun which matches the answer.

'there's no longer a blasted tree?' is the wordplay.
'there's' means one lot of letters go next to another.
'no longer' becomes 'ex' (prefix meaning former or onetime).
'a blasted' is an anagram indicator.
'tree' anagrammed gives 'eter'.
'ex'+'eter' is 'EXETER'.
