Kiss tutor working in Borders (9)
I believe the answer is:
outskirts
'borders' is the definition.
(I've seen this before)
'kiss tutor working' is the wordplay.
'working' indicates anagramming the letters.
'kiss'+'tutor'='kisstutor'
'kisstutor' is an anagram of 'OUTSKIRTS'.
'in' acts as a link.
(Other definitions for outskirts that I've seen before include "Suburbs" , "borders" , "Edges (of town)" , "surrounding area" , "area away from town centre" .)
