Denise Norbury will conceal the Spaniard (5)
I believe the answer is:
senor
'the spaniard' is the definition.
('mister' in Spanish)
'denise norbury will conceal' is the wordplay.
'conceal' says the answer is hidden in the clue.
'SENOR' can be found hidden inside 'denise norbury will'.
(Other definitions for senor that I've seen before include "Spanish for Mr" , "A Spanish mister" , "Man in Havana ?" , "Norse (anag.)" , "Snore like Spanish man" .)
