Butcher provides service with care, surprisingly (8)
I believe the answer is:
massacre
'butcher' is the definition.
(I've seen this before)
'service with care surprisingly' is the wordplay.
'service' becomes 'mass' (kind of church service).
'with' means one lot of letters go next to another.
'surprisingly' indicates anagramming the letters (a surprising ordering of the letters).
'care' is an anagram of 'acre'.
'mass'+'acre'='MASSACRE'
'provides' acts as a link.
(Other definitions for massacre that I've seen before include "Butchery" , "Slaughter of large number of people" , "Carnage" , "Overwhelming defeat" , "Yours and mine" .)
