Head of facilities on the hunt? (7)
I believe the answer is:
looking
'the hunt?' is the definition.
(looking is a kind of hunt)
'head of facilities on' is the wordplay.
'head of' becomes 'king' (I can't justify this - if you can you should give a lot more credence to this answer).
'facilities' becomes 'loo' (I've seen this in other clues).
'on' is a charade indicator (letters next to each other).
'king' after 'loo' is 'LOOKING'.
Can you help me to learn more?
(Other definitions for looking that I've seen before include "Watching" , "Directing the eyes towards" , "Seeming to be; gazing" , "Observing" , "Appearing (like)" .)
