Barrister secretly concealing brief (5)

I believe the answer is:

terse

'brief' is the definition.
('terse' can be a synonym of 'brief')

'barrister secretly concealing' is the wordplay.
'concealing' indicates a hidden word.
'TERSE' is hidden in the letters of 'barrister secretly'.

(Other definitions for terse that I've seen before include "Brusque, concise" , "Trees (anag.)" , "Brusque and curt" , "Curtly brief" , "Briefly expressed" .)

I've seen this clue in The Telegraph.
