Dean Hunter is out of place below (10)
I believe the answer is:
Here is my best explanation:
'below' is the definition.
'dean hunter is out of place' is the subsidiary indication.
'is out of place' indicates an anagram.
'deanhunter' is an anagram of 'underneath'.
(Other definitions for underneath that I've seen before include "on the hidden side", "Lower", "Below" and "bottom".)
