A thrill for the protégé (6)
I believe the answer is:
Here is my best explanation:
This clue is a double definition.
'a thrill' is the first definition.
('charge' can be a synonym of 'thrill')
'the protege' is the second definition.
'for' is the link.
(Other definitions for charge that I've seen before include "Lord Cardigan's order to his brigade", "Sortie", "Entrust (with a task)", "Accusation (in court)", "In which an offender may be given", "Load - price", "Legal accusation", "Make a rush at", "15 - or required payment" and "responsibility".)
