One interrogating angry ex, a pitman? (5-8)

I believe the answer is:

cross-examiner

'one interrogating' is the definition.
(I know that cross-examiners interrogate people)

'angry ex a pitman?' is the wordplay.
'angry' becomes 'cross' (cross can mean annoyed or angry).
'pitman?' becomes 'miner' (pitman is a kind of miner).
'cross'+'ex'+'a'+'miner'='CROSS-EXAMINER'

(Another definition for cross-examiner that I've seen is " One questioning a witness".)

I've seen this clue in The Times.
