Crossword Genius

Destroy detective's cover (9)

Ross

I believe the answer is:

dismantle

'destroy' is the definition.
(dismantling is a kind of destroying)

'detective's cover' is the wordplay.
'detective's' becomes 'dis' (Detective Inspector).
'cover' becomes 'mantle' (mantling is a kind of covering**).
'dis'+'mantle'='DISMANTLE'

(Other definitions for dismantle that I've seen before include "Unrig" , "Undo" , "Strip down" , "Pull to pieces" , "To demolish" .)

I've seen this clue in The Telegraph.
