Nora’s terrible torching (5)

I believe the answer is:

arson

'torching' is the definition.
(I've seen this before)

'nora's terrible' is the wordplay.
'terrible' is an anagram indicator.
'noras' is an anagram of 'ARSON'.

(Other definitions for arson that I've seen before include "Incendiary crime" , "serious offence" , "major crime" , "A burning crime" , "Incendiarism" .)

I've seen this clue in the Evening Standard.
