Arsonist gutted pretty country clubs (10)
I believe the answer is:
pyromaniac
'arsonist' is the definition.
(both can mean a fire starter)
'gutted pretty country clubs' is the wordplay.
'gutted' says to hollow out the word (remove centre letters) (to gut something is to remove its insides).
'country' becomes 'romania' (Romania is an example).
'clubs' becomes 'c' (abbreviation used in card games such as bridge).
'pretty' with its centre removed is 'py'.
'py'+'romania'+'c'='PYROMANIAC'
(Other definitions for pyromaniac that I've seen before include "Arsonist" , "Fire-raiser" .)
