Awful house with Rolls Royce inspector recalled (6)
I believe the answer is:
horrid
'awful' is the definition.
(I've seen this before)
'house with rolls royce inspector recalled' is the wordplay.
'house' becomes 'ho' (abbreviation for house).
'with' means one lot of letters go next to another.
'rolls royce' becomes 'rr' (short for Rolls Royce).
'inspector' becomes 'di' (abbreviation for Detective Inspector).
'recalled' says the letters should be written backwards (to recall can mean to bring something back).
'di' reversed gives 'id'.
'ho'+'rr'+'id'='HORRID'
(Other definitions for horrid that I've seen before include "Repulsive" , "Dreadful" , "Hideous" , "Repellent" , "Distasteful" .)
