Question old flame, an explosive type? (7)

Ross

I believe the answer is:

examine

'question' is the definition.
(I know this)

'old flame an explosive type?' is the wordplay.
'old flame' becomes 'ex' (an ex-lover).
'an' becomes 'a'.
'explosive type?' becomes 'mine' (mine is a type of explosive).
'ex'+'a'+'mine'='EXAMINE'

(Other definitions for examine that I've seen before include "Closely study" , "vet" , "Test or study carefully" , "Inspect , test" , "Inspect, peruse closely" .)

I've seen this clue in The Times.
